Genetic information, stored in the chromosomes and transmitted to daughter cells through DNA replication, is expressed through transcription to RNA and translation into proteins (polypeptide chains). The pathway of protein synthesis is called translation because the “language” of the nucleotide sequence on the mRNA is translated into the “language” of an amino acid sequence. The process of translation requires a genetic code, through which the information contained in the nucleic acid sequence is expressed to produce a specific sequence of amino acids. Any alteration in the nucleic acid sequence may result in an incorrect amino acid being inserted into the polypeptide chain, potentially causing disease or even death of the organism.

why don\'t most other types of bacteria produce ulcers ( like helicobacter pylori bacteria) Solution helicobacter is a chronic inhabitant usually persists for lifelong(unless treated) in gastric mucosa. Helicobacter can capable of staying for longer in host so it can able to modulate the localized host tissue by producing cytokinines. these cytokinines are plays important role in ulcer pathogenesis. bacterial virulence factors cytotoxin-associated gene pathogenecity island encoded protein CagA and cytotoxin Vac A are could be responsible of ulcer pathogenesis. unlike other bacteria helicobacter can able to produce cytotoxins which can cause immune mediated tissue damage leads to ulcer formation.

You will construct a manual for your company that defines the Risk Management Policy for all future projects. For this, you can adopt the perspective of either a: - Option 1: o For Profit Company that develops new products, and each product might be considered a project. For this you will adopt the perspective of a Project Management Office (PMO) and you are developing the manual that is used by all Project Managers (PM) who will be conducted a risk assessment for all future projects. - Option 2: o City or town that has many projects in development or underway, such as park operations, traffic operations, public works, etc… For this you will adopt the perspective of a risk manager for a production facility or city/town, and you are drafting policy for risk assessments of worker safety Whether you select Option 1 or Option 2, you will draft the manual using the tools and materials that we have reviewed in Weeks 1 through 4 of this class. The manual should be in a form such that a reasonably educated and informed individual is able to pick the manual up, and have enough guidance for implementing the policy. If you think about some of the documents we have reviewed thus far, they are a mix of policy, guidance and specific methodologies. Your manual should follow the same general form: - What is the general purpose of the manual - What is the interaction between policy and implementation - What specific method are employed to assess the risk so that it can be managed It is expected that - you will select two or more (but certainly not all) of the methods from the ISO and USCG documents as the official method used to assess risk within your organization. - Offer guidance as to when some specific method should be employed. Notice that this format follows the USCG Risk-based Decision Making (RBDM) wherein they offer substantive guidance as to which method should be used for which situation. This is compared to the ISO document which offers generalities as to risk management policy, but offer limited guidance as to when to use specific methods. Therefore, the project is NOT expected to be 27 pages of text (for example), but it IS expected to be more than 5. Maybe 10? It all depends on what is necessary to get the job done. - It is up to you, the student, to determine what is required based on your understanding of the material thus far, and to draft a manual that is robust enough that you would feel comfortable submitting to your supervisor if that supervisor asked for a risk management manual to be drafted. The basic question is: what do you think this manual would look like? - What is you organizational process for answering the 5 questions for any new project that is being considered - There should be enough procedure and guidance information that the user is able to open the document and leverage it towards a robust risk assessment that can be applied to the 90% situation - Submit this as a ‘professional’ manual that you might find in the risk ma.

You observe a cell switch from performing cellular respiration to performing lactic acid fermentation. Why would a cell make this switch? because there isn\'t enough glucose available because there is too much carbon dioxide in the cell because the cell needs lactic acid to obtain the extra ATP from fermentation because there isn\'t enough oxygen for cellular respiration Solution because there isn\'t enough oxygen for cellular respiration Explanation: In the absence of oxygen as the terminal electron acceptor the reduced coenzymes - NADH accumulate. Cell needs NAD+ to keep the glycolysis running. So the cell switches to lactic acid fermentation to regenerate NAD+..

What could be the rational for IRC exempting income from bonds issued by States and other municipalities from being taxable? Solution Municipal Bonds- These are issued by local and state Government for financing a project. These bonds provide less but fixed return. Rational behind exempting the income from municipal bonds from being taxable- Municipal bonds are issued to finance for the Government projects. These provide very less return to the public and provide no addional income except the interest, that is the reason most of the municipal bonds\' interest is tax exempt from all federal income taxes..

We learn of the the black dwarf, the final stage in a death of a low mass star. What happens to a black dwarf after it cools to nearly zero Kelvin over trillions of years? Is there any other stage, or does it just remain as an Earth sized burned out ember for eternity? Solution It needs to be understood here that black dwarfs are essentially theoretical. The age of the universe is around 14 billion years which happens to be too short a time for a white dwarf to emit all of its heat out. However, theoretically when this would happen, the white dwarf would reach a stage when its temperature would be down to a level that the radiation coming out of it would become same as the background cosmic radiation and will become invisible to us. That is, it will continue to cool down until it reaches the temperature of its surrounding, a cold mass with nothing to emit or absorb, and would remain so..

Q i.Why is it, in general the fracture toughness of ductile materials greater than materials with high hardness? Q ii. Explain why BCC metals exhibit a Ductile - Brittle Transition Temperature while FCC metals do not. Solution 1)Ductility is more commonly defined as the ability of a material to deform easily upon the application of a tensile force, or as the ability of a material to withstand plastic deformation without rupture. Ductility may also be thought of in terms of bendability and crushability. Ductile materials show large deformation before fracture. The lack of ductility is often termed brittleness. Usually, if two materials have the same strength and hardness, the one that has the higher ductility is more desirable. The ductility of many metals can change if conditions are altered. An increase in temperature will increase ductility. A decrease in temperature will cause a decrease in ductility and a change from ductile to brittle behavior. As the hardness of a material increases the ductility propertry decreases and brittlness increses therefore toughness dcreases. 2) The ductile-brittle transition is exhibited in bcc metals, such as low carbon steel, which become brittle at low temperature or at very high strain rates. Fcc metals, however, generally remain ductile at low temperatures. In metals, plastic deformation at room temperature occurs by dislocation motion. The stress required to move a dislocation depends on the atomic bonding, crystal structure, and obstacles such as solute atoms, grain boundaries, precipitate particles and other dislocations. If the stress required to move the dislocation is too high, the metal will fail instead by the propagation of cracks and the failure will be brittle. Thus, either plastic flow (ductile failure) or crack propagation (brittle failure) will occur, depending on which process requires the smaller applied stress. In fcc metals, the flow stress, i.e. the force required to move dislocations, is not strongly temperature dependent. Therefore, dislocation movement remains high even at low temperatures and the material remains relatively ductile. In contrast to fcc metal crystals, the yield stress or critical resolved shear stress of bcc single crystals is markedly temperature dependent, in particular at low temperatures. The temperature sensitivity of the yield stress of bcc crystals has been attributed to the presence of interstitial impurities on the one hand, and to a temperature dependent Peierls-Nabarro force on the other. However, the crack propagation stress is relatively independent of temperature. Thus the mode of failure changes from plastic flow at high temperature to brittle fracture at low temperature..

Problem 1. Think about an individual that you are investigating from engineering analysis perspective. A few years back, when he first visited DC, the price for a 7-day unlimited pass MetroRail ticket was $10. Without knowing the spurt in rail ticket price, he moved to DC very recently without purchasing a vehicle and planned to take Metro to museums and restaurants and for commuting trips, too. Then, he found out the price for Metro tickets tripled. Use your engineering knowledge to forecast or predict which of the following travel plan decisions would change for this person? 1. The total number of trips made in DC; 2. The mode of transportation he uses for travel; 3. Any other perspective of trips he makes. Can you also identify the possible rationale behind all these changes? Problem 2. Name three simplifying assumptions that are used in the mode choice and route choice steps. Pick one of them, and then explain how you could change the procedure to relax this assumption and make the process more realistic. Solution.

Junior collects baseball cards. He owns one Felix Hernandez card that sells in most shops for $15. He is interested in buying a different Felix card that also sells for $15. According to behavioral economics: A. Junior should value the two cards equally and be willing to trade one for the other. B. the availability heuristic will cause Junior to value more highly the card he doesn\'t have. C. the endowment effect would suggest that Junior would not be willing to trade the card he has for the card he doesn\'t have. D. prospect theory says he will buy the second card as both have the potential to appreciate in value. Solution The rational behavior would suggest that the individual should value both the cards equally and be willing to trade one for the other in order to obatin felix card, he does not have. The value of both the card should be same in order for the individual to attain optimal level of utility, otherwsie he will be worse off at sub-optimal level. Assume, his felix hernandes card worth more than what is being sold in the market, then by exchanging the card he will be worse off buy the difference in amount. If on ther otherhand, the card he hold worth less in the market, and if he wish to exchange then it would be not possible for him to do so, as the other party wont accept it. Again, in this circumstances he would still be worse off. Hence, the card should be equally worth and parties in contract should be willing to exchange. The correct answer is A..
