A wild-type chromosome has the following segments: A B C middot D E F G H I An individual is heterozygous for the following chromosome mutation: A B C middot D H I How would the mutated and wild-type chromosomes pair in prophase I of meiosis? D E F G H of the wild-type chromosome will form a deletion loop. E F G of the wild-type chromosome will form a deletion loop. D E F G H of the wild-type chromosome will form an Inversion loop. E F G of the wild- type chromosome will form an inversion loop. Red-green color blindness is a human x-linked recessive disorder. A young man with a 47, XXY karyotype (Klinefelter syndrome) is color Wind. His 46, XY brother also is color blind. Both parents have normal color vision. Where did the no disjunction that gave rise to the young man with Klinefelter syndrome take place? Assume that no crossing over took place In prophase I of meiosis. Mother - meiosis I Mother - meiosis II Father - meiosis I Father - meiosis II Both parents Functional epidermal lies bull nose (JEB) Is a severe skin disorder that results in blisters over the entire body. The disorder is caused by autosomal recessive mutations at any one of three loci that help to encode lamina 5, a major component In the dermal-epidermal basement membrane. Leena Pulicine and colleagues described a male newborn who was born with JEB and died at 2 months of age (L. Pulkkinen et al. 1997. American Journal of Human Genetics 61:611-619); the child had healthy unrelated parents. Chromosome analysis revealed that the infant had 46 normal-appearing chromosomes. Analysis of DNA showed that his mother was heterozygous for a JEB-causing allele at the LAMB3 locus, which is on chromosome 1. The father had two normal alleles at this locus. DNA fingerprinting demonstrated that the male assumed to be the father had, In fact, conceived the child. Assuming that no new mutations occurred in this family, what might best explain the presence of an autosomal recessive disease in the child when the mother is heterozygous and the father Is homozygous normal? The infant inherited both copies of chromosome 1 from the mother, which is an example of unit parental disomic. The infant is monatomic for chromosome 1, which he received from his mother but did not receive a chromosome 1 from his father. Epitasis masked the disease phenotype in the father, but complementation of the parental alleles gave rise to a child with functional epidermal lies bull nose. The infant has tiresome 1, where he inherited two recessive alleles from his mother. A translocation between chromosome 1 and chromosome 22 generated a recessive phenotype. Plasmid DNA, like bacterial DNA: is circular. is single stranded. comes in homologous pairs. All of the above. None of the above. Solution 10. Answer is B. EFG of the wild type will form a deletion loop. Because EFG in one chromosome has no matching pair in other chromosome. So EFG loop will be formed and it will be removed. 13. Answer is A. Plasmid DNA like bacte.

A laser range finder was used to sense the obstacles. What parameter will the microcontroller record? If an obstacle is 5m away, what will be the recorded value? Solution The main function of the microcontroller is to record the time measurement from the time-measuring unit, average the time measurements and calculate the distance. After the distance is calculated, the data is transmitted to a PC. The microcontroller sends the signals to start the counter for the time measurement unit and to send the laser light pulse. Also, the microcontroller is used to initiate and set the parameters of the time measurement unit (speed, mode, resolution, etc.) After the time measurement unit calculates the time, the microcontroller reads and stores the time information. At least fifty time measurements are taken from each distance to be measured. The more samples taken the most accurate the results are, but the more time needed to obtain the distance measurement. Once the microcontroller has obtained the values for the time and computes their average, it calculates the distance value and transmits it to a PC using USART interface. Each distance calculation should take less than 20ms. This time depends on the number of time measurements taken and the duty factor of the pulse laser diode Laser Diode Driver This section outlines the function of the laser driver. The main function of this driver is to provide fast, high current pulses to drive the PLD. The PLD is operated in a short pulse mode in order to achieve high peak powers with fast rise and fall times The amount of current generated by the driver must be limited not to exceed the maximum forward current of the PLD. In order to maximize the optical power of the PLD, a collimating lens is used to minimize the divergence of the laser beam. Receiving Channel Hardware A small fraction of the light beam emitted by the PLD is received by an optical receiver and focus on the APD which photo-electrically convert the pulse of light received. The small pulse of current generated by the APD is converted into a TTL voltage level signal using a two-stage transimpedance amplifier. This voltage signal serves as the STOP signal for the time counter. To measure the time of flight of the emitted pulsed of light, an ultra-fast counter as a TDC is used. TDCs are used to measure the time intervals between two events with a resolution of less than one nanosecond. The accuracy of a pulsed TOF laser radar depends critically on the performance of its time measurement unit. Therefore, a high resolution and a high speed TDC is needed to improve the system performance.. High Voltage Power Supply To reach the proper gain and responsivity of the APD, a high voltage is used to reverse bias the APD. This high voltage is generated and stabilized using a high voltage DC-DC converter which provides up to 400V output from a 5V input. The high voltage DC-DC converter must provide a low voltage noise and low voltage ripple. Increasing the v.

Which one is NOT typical of a ceramic material? low melting point high hardness high stiffness ionic bonding Solution ans : A Ceramic materials have high melting point Ceramics usually have a combination of stronger bonds called ionic (occurs between a metal and nonmetal and involves the attraction of opposite charges when electrons are transferred from the metal to the nonmetal); and covalent (occurs between two nonmetals and involves sharing of atoms). The strength of an ionic bond depends on the size of the charge on each ion and on the radius of each ion. These types of bonds result in high elastic modulus and hardness, high melting points, low thermal expansion, and good chemical resistance. On the other hand, ceramics are also hard and often brittle (unless the material is toughened by reinforcements or other means), which leads to fracture..

4. Define communication security, information security, network security, physical security with example. Solution Communication Security The protection resulting from all measures designed to deny unauthorized persons information of value that might be derived from the possession and study of telecommunications, or to mislead unauthorized persons in their interpretation of the results of such possession and study. Also called COMSEC. Communications security includes: cryptosecurity, transmission security, emission security, and physical security of communications security materials and information. a. cryptosecurity--The component of communications security that results from the provision of technically sound cryptosystems and their proper use. b. transmission security--The component of communications security that results from all measures designed to protect transmissions from interception and exploitation by means other than cryptanalysis. c. emission security--The component of communications security that results from all measures taken to deny unauthorized persons information of value that might be derived from intercept and analysis of compromising emanations from crypto-equipment and telecommunications systems. d. physical security--The component of communications security that results from all physical measures necessary to safeguard classified equipment, material, and documents from access thereto or observation thereof by unauthorized persons. Physical Security Physical security is the protection of personnel, hardware, software, networks and data from physical actions and events that could cause serious loss or damage to an enterprise, agency or institution. This includes protection from fire, flood, natural disasters, burglary, theft, vandalism and terrorism. Physical security has three important components: access control, surveillance and testing. Obstacles should be placed in the way of potential attackers and physical sites should be hardened against accidents, attacks or environmental disasters. Such hardening measures include fencing, locks, access control cards, biometric access control systems and fire suppression systems. Second, physical locations should be monitored using surveillance cameras and notification systems, such as intrusion detection sensors, heat sensors and smoke detectors. Third, disaster recovery policies and procedures should be tested on a regular basis to ensure safety and to reduce the time it takes to recover from disruptive man-made or natural disasters. Information Security Information security (infosec) is a set of strategies for managing the processes, tools and policies necessary to prevent, detect, document and counter threats to digital and non-digital information. Infosec responsibilities include establishing a set of business processes that will protect information assets regardless of how the information is formatted or whether it is in transit, is being processed or is at rest in storage.

What is the general location of the three different types of amino acids in the typical soluble protein? In the typical nonsoluble membrane protein? Solution Aminoacids, the monomeric units that link together to form proteins, have a standard structure. The carbon atom of each amino acid is bonded to four various compound groups and ergo is asymmetric. The side chain have R group. Aminoacids could be classified into a few distinct categories based primarily on their solubility in water, which can be influenced by the polarity of their area chains. Proteins with polar side groups tend to be on the surface of proteins; by connecting with water, they make proteins soluble in aqueous solutions. In comparison, amino acids with nonpolar side groups avoid water and aggregate to make the water insoluble core of proteins. The polarity of amino acid side chains thus is one of the forces responsible for shaping the final three-dimensional structure of proteins. Hydrophilic or water-soluble, amino acids have ionized or polar area chains. Hydrophobic amino acids have aliphatic side organizations, which are insoluble or only slightly soluble in water..

The vast majority of commenters envision a strong role for the FASB in the endorsement of IFRS and that they expect the FASB to be able to exert influence on the standard-setting process of the IASB through this endorsement role. How Does Convergence Fit into the FASB’s Mission? Solution Answer: This considerations is unique to the US. Such a mechanism can serve as an important ‘sovereignty circuit-breaker’ to ensure that international rules do not automatically form a part of national law. Such arrangements are used by the majority of IFRS jurisdictions and are respected by the IASB. We also understand that US respondents wish to see a strong role for the FASB. From the IASB perspective, it is clear that the US’s contributions to the future Accounting Standards Forum and to the standard-setting process of the IASB would have greater weight if the US were to employ an endorsement approach to the use of IFRS..

The horizontal blocks below help summarize functional features associated with a proteins amino acid sequence with the N-terminal at left and the C-terminal at right. For the two proteins displayed SP indicates a signal peptide, and GFP is green fluorescent protein. The single letters at the C-terminus of the constructs are amino acid abbreviations. Based on your understanding of protein secretion in eukaryotic cells, at the right of each protein predict all locations in the plant cell where you would expect to see fluorescence by GFP after expression in plant cells and examination for fluorescence. Solution Answer: (a) Because of its small size, GFP can enter nuclear pores. So, GFP protein not fused to other polypeptides can be seen in both cytoplasm and nucleus in plant cells when monitored under fluorescence microscopy. (b) Addition of ER-retension sequence, SEKDEL to a recombinant protein results in the retention of the protein in the endoplasmic reticulum (ER). So, the above sequence containing the SEKDEL sequence can be predicted to be seen in the ER- derived vescicles/compartments and partial localization in protein storage vacuoles within the cell..

Problem 6.64 sace trig t onta Foe-t/T is exerted on the object. At t 0, an object of mass m is at rest at z = 0 on a horizontal, frictionless surface. Starting at t = 0, a horizontal force Solution The force acting on the particle is given as Foe-t/T We know that acceleration = Force / mass Hence, acceleration = a(t) = (Fo/m)e-t/T Further, for any motion, we know that dv /dt = a(t) Rearrganging the terms, we get: dv = a(t) dt or dv = (Fo/m)e-t/T dt We will have to integrate the above relation to get the velocity at any time t Part A: Hence, V = -(FoT/m)[e-t/T - 1] = (FoT/m)[1 - e-t/T] Part B: For the above relation of V, we need to find the value of V for t tending to infinity. For t tending to infinity, e-t/T will tend to zero. Hence, Velocity after a very long time = (FoT/m) NOTE: For questions involving force or acceleration dependent on time, we would need to employ dv/dt = a(t) to determine the relation for dV which can then be integrated to obtain V at any point. Plus, similar relation as ds/dt = v(t) can be used in case displacement is to be determined..

Measure the accounting for foreign currency and its translation. Scenario CM Corporation (CMC) was founded six years ago by Phil Connor and Eric Martin. The company designs, installs, and services security systems for high-tech companies. The founders, who describe themselves as \"entrepreneurial geeks,\" met in a computer lab when they were teenagers and found they had common interests in working on security systems for critical industries. CMC hired you as a junior accountant this year. Lately, Connor and Martin have been working with \"radio frequency identification\" (RFID) technology. They have developed a detailed system designed to track inventory items using RFID tags embedded invisibly in products. This technology has numerous inventory applications in multiple industries. One of the most basic applications is tracking manufacturing components; if tagged components \"go walking\" (if employees attempt to take them), companies can easily track and find them. Connor and Martin have sold their system to several high-tech companies in the area. These companies have a number of government contracts that require extensive security systems to protect sensitive data from infiltration by terrorists and others. To date, CMC\'s cash flow from sales and services has adequately funded its operations. CMC expects much growth potential for its products. As a result, they are considering going public and expanding internationally in the near future. Instructions Connor and Martin are contemplating international business in their industry and feel that global expansion is a great transition for the company. They feel they understand IFRS much better in addition to having a greater technical grasp of GAAP. They have decided to go public and also expand internationally within the next two to three years. With making such bold moves, they are also seriously considering a switch to IFRS as their accounting standards for financial statements. Connor and Martin have requested your assistance in creating a PowerPoint presentation that summarizes information on the impact of foreign currency should the firm expand internationally. Presentation Mechanics should be as follows: Prepare a 5-8 slide PowerPoint presentation, including slide notes. Summarize the impact foreign currency will have on a firm expanding internationally. Explain the advantages and disadvantages to foreign currency translation of financial statements. Explain different reasons for the firm to continue with accounting under US GAAP or switching to IFRS standards. Solution Impact Of Foreign Currency on a firm expanding internationally 1) Be on top of the exchange rate It goes without saying that following exchange rates is extremely important. International business requires having a very good sense of how your local currency is affected by other currencies and how that, in turn, has an impact on your exports, imports, suppliers, clients, etc. 2) Research past rates There is no need to do d.
