A mutant strain of E. coli is found that produces both beta-galactosidase and permease at high levels whether lactose is present or not. (a) What are two possible genotypes for this mutant? Another mutant is isolated that produces no beta-galactosidase at any time but produces permease if lactose is present in the medium. A merodiploid strain is formed from these two mutants. in the absence of lactose, neither beta-galactosidase nor permease is made. When lactose is added, the merodiploid strain makes both beta-galactosidase and permease. (b) What is the genotype of the merodiploid strain? Solution A mutant of E. coli is found that produces both beta - galactosidase and permease at high levels in the presence or absence of lactose a) The two possible genotypes for this mutant is given as-: F+ Z+ Y+ Now another mutant is isolated that produces no beta-galactosidase at any time but produces permease if lactose is present in the medium. The genotype for this mutant is given as-: F- Z- Y- Given a merodiploid strain is formed from these two mutants. Merodiploid is partially diploid bacterium having its own chromosome and a fragment that is introduced either by conjugation, transformation or transduction. It is given by-: F+ Z+ Y+ x F- Z- Y- =F\' Z+ - Y- b) The genotype for the merodiploid strain is F\' Z+ - Y- For Merodiploid strain in the absence of lactose, neither beta-galactosidase nor permease is formed but in the presence of lactose both beta-galactosidase and permease is produce. As mutant 1 have the ability to make beta-galactosidase in the absence or presence of lactose but the mutant 2 is unable to make beta-galactosidase at any time so in the new mutant the gene for beta galactosidase is expressed only in the presence of lactose. Also the permease producing gene of 2 mutant is dominant that is the reason the merodiploid strain produces permease in the presence of lactose but not in the absence of lactose..

An unknown individual launches a series of attacks against the Web sites of Prime Sales Corporation. The attacks significantly slow the sites, leading to $100 million in damage in terms of lost work time, lost revenue, site repair costs, and other expenses. The attacker does not intend to profit from the onslaught and in fact does not realize any financial benefit from the effects. How is this attack most likely orchestrated? Who is most likely to engage in this act—that is, whose habits and limitations are clearly suited to such conduct—and why? Solution Most probably the website is slowed by a DDOS (Distributed Denial of Service) attack. In this attack the hacker sends multiple fake requests from different servers with the intention of slowing down the service to legitimate users. The most likely suspect is an anonymous hacking group. These groups are formed by professional hackers who come together for a common cause. The most likely reason might to gain attention or the group considers something the company is doing as against their beliefs..

You\'ve completed an interrupted mating experiment in E. coli, the leu gene enters before the aln gene. For this experiment, you crossed an Hfr that is leu^+ gln^+ with an F- that is leu^- gln^-. Exconjugant cultures are plated on minimal medium supplemented with leonine but not glutamine, and 250 total colonies were observed. Each of those colonies was then plated on minimal medium containing no leonine or glutamine; only 200 of the cultures grew under these conditions. What are the genotypes of the two different cultures? So, what likely happened at the cellular/molecular level to allow some cells to grow without glutamine supplementation, but not all? Make sure you explain/support your answer. (lessthanorequalto 4 sentences) Solution a) leu and gln gene\'s are the genotypes of the two different cultures. b) because of this minimal medium supplemented and Hfr , F for combination of any two moleucles or ions the opposite signs of its bonding makes stable for a molecule. so, this molecules will allow.this makes cellular/moleculer level to allow some cells to grow without glutamine supplementation..

Write a C program to enter a first name, middle name and last name in separate variables. After entering each name at the keyboard, call a function named convert that will capitalize the first letter of the name and set the rest of the name to lowercase (for example, jOhN becomesJohn). The convert function will be called three times-- once for the first name, once for the middle name, and once for the last name. Combine the properly capitalized names into one string and output the string (make sure you have a space between each part of the name). Count the number of characters in the total name (including spaces between names) and output that total also. Include descriptive comments in your source code. Solution #include #include #include void Convert(char string[]) { int i; int len = strlen(string); //compute length of string string[0] = toupper(string[0]); // capitalize first character of the string for (i=1;i.

Why do the soft technologies open more opportunities for women? To what extent have these technologies impacted the perceptions of men’s and women’s roles in the economy, within marriage, and in society as a whole? Solution Now a days Woman is playing a very important role in every field of the economy.Either Agriculture or education or any part of the manufacturing area. I am also agree from this statement, beacuse after marriage so many responsibilities increase its libilities through these soft techniqe she can hendle her all task very easily. Technology is a vital element for any community. It plays a significant role in food security, agriculture and small scale production. Women use technical skills and knowledge in their daily activities; they continually innovate and adapt technologies in response to things they face in their everyday lives. However, their role and technical skills are often overlooked and undervalued. There are four main reasons why women are less visible in the application of technology than men:.

Which of the following occurs with disruptive selection a. Natural selection favors phenotypes of one extreme, resulting in a population mean shift over several generations b. Natural selection favors phenotypes of both extremes, resulting in an increase in intermediate phenotypes over time c. Natural selection favors phenotype values near the population mean, resulting in no shift in mean trait value over time and a more narrow bell curve d. Natural selection selects against trait values that are close to the population mean, resulting in a bimodal distribution of trait values Solution Disruptive selection happens when conditions favor individuals at both extremes of a phenotypic range over individuals with intermediate phenotypes. one example is a population of black- bellied seedcracker finches in Cameroon whose members show two distinctly different beak sizes. small-billed birds feed generally on soft seeds, whereas large-billed birds specialize in cracking hard seeds. it seems that birds with intermediate-sized bills are comparatively inefficient at cracking both types of seeds and thus have lower relative fitness..

What are two specialized epidermal cells and what do they do for the plant? Solution The two specialized epidermal cells in the plant are 1. Guard cells 2. Trichome. Guard cells are kidney shaped cells with rich green chloroplasts.Guard cells occur in form of pairs. A pair of guard cells and pore are referred as stomate. Guard cells perform two different functions. At daytime, guard cells open small pores in the plant epidermal surface allowing carbon dioxide to diffuse from atmosphere into the chlorenchyma tissue required for the photosynthesis process. It also regulates oxygen exchange. At night-time guard cells close the pores in the epidermal cells preventing water loss from leaves. Guard cells can alter the size of stomata by changing its structure in response to water exchange. Trichomes are branched hairy projections of modified epidermal cells. Trichomes are multi cellular with spine shape or hook shaped. Trichomes are branched or unbranched, unicellular or multicellular. Trichomes function to prevent water loss through evapouration and retains moisture. It secretes a sticky substance that repels insects..

What are the basic differences and commonalties between Structured Analysis (process- oriented). Information Engineering (data-oriented), and Object-Oriented approaches for software development? Solution Structured Analysis is technique used in software development to analyse the designed system to its correctness. The analysis is made to see to what extent the designed system meets the requirement of the user. The structured analysis uses data flow diagrams to analyze the designed structure. It is believed that if the structure is good then the data will be good, but doesnot pay attention on data in detail. Data oriented analysis is used where data plays the utmost role. The diagrams that are used for analysing the data oriented design is ER diagrams. Data oriented design establishes the relations that are required for the development of the system on various data.The data analysis concentrates on incorporating additional features in process to ensure the data integrity. Object oriented analysis unlike of the above two concetrates on the objects, which are the instance of class that consists of both data and process or logic. The data oriented anaylsis cannot work on the structured process. similalry structures analysis cannot be performed on data oriented design.The process oriented and object oriented analysis are widely in use when compared to data oriented analysis..

The nucleus is something we are debating on Celia\'s thread too. Although not called a nucleus, but rather a nucleoid in the prokaryotic cell, how does the organization of genetic material differ in the prokaryotic cell? Solution Ans. The genetic material of both eukaryotes and prokaryotes are chemically the same- being constituted of A, C, T G nucleotides forming double stranded DNA helix. However, their organization (from naked DNA to chromosome) differ in following aspects- I. Eukaryotic DNA is always linear, whereas that of prokaryotes is circular. II. Eukaryotic DNA is associated with basic histone proteins that facilitates its supercoiling to 30nm fiber. Prokaryotes lack histone proteins. Instead prokaryotic DNA is associated with various nucleoid- associated proteins, histone-like proteins and transcription factors that facilitate its condensation into loosely-packed loops. III. Eukaryotic genome is housed in a double membrane- bound organelle called the nucleus. Prokaryotes lack membrane bound organelles including nucleus. The regions of prokaryotic cytoplasm where genomic DNA is present in condensed form is called nucleoid..

1. My anatomy: I am quite small as compared to many microorganisms. Members within my family are typically too small to be observed with an optical microscope. My chemical composition includes relatively few proteins and a lipid bilayer. 2. My growth and metabolism: I am an obligate parasite relying on a cellular host to reproduce. Independent of my host, I have no metabolism. 3. My genetic makeup: whether it is in the absence or in the presence of my host, the genetic information which I use to replicate myself is never in the form of DNA. As a free entity, my genetic information is encoded by a coding RNA (positive). However, I can also generate non-coding RNA during my life cycle within the cell. 4. I am fairly restricted in the hosts in which I am pathogenic, being limited to primates such as humans. 5. The symptoms associated with the disease that I cause include feeling tired, fever, weakness, headache, and a sore throat. In more severe cases, hosts will bleed from their mouths and their eyes as well as vomit blood. 6. My origins are thought to be in Africa from where I spread to the Americas through the slave trade. 7. I am not directly transmitted from primate to primate. I require a vector, which like a good acquaintance of mine the malaria causing pathogen, is the mosquito. 8. The first report of an epidemic in the Americas for which I am held responsible occurred in 1648 where I am held accountable for destroying the Yucatan Mayans. Solution The disease described here is yellow fever, which is caused by the yellow fever virus, arbovirus of genus flavivirus. The vector is mosquito Aedes aegypti..
