Q1. The proteins RhaA and RhaB are formed by the Rha Operon. Find out that there is a regulator protein Rha O that binds to the Rha operator sequence and activates transcription of the Rha operon. Rha O is encoded by a separate gene.
You find a mutant bacteria cell that is able to express a normal RhaA protein but no RhaB protein. You isolate mRNA from the bacteria and find that there are normal levels of both RhaA and ThaB mRNA. List two possible mutations that might cause this phenotype. Be as specific as possible about the location of mutation.
Q2. Sami has been hospitalized with acute gastritis. Her symptoms were epigastric pressure (just above the stomach), headache, nausea, and vomiting. She revealed that she had been suffering back pain and drank four shots of gin and took three aspirin to "kill the pain." What led physician to make this diagnosis, and what might have caused the sudden attack?
If you transform bacteria with the plasmid library made in part b above, divide the transformatnts into 20 aliquots and find one has the insert of interest, now how many clones do you need to screen.
What promotes exponential growth? What constrains population development.
How do these duplications arise and what do they propose in terms of mechanisms of transposition. Could you help to understand FEV1/FVC and how the expected percentage of this figure relates to respiratory problems.
Find out the genotypes of the two black females and the brown male using allele symbols B and b. One shows linear carbon chains, another has one -CH3 groups present on the third carbon atom, and third has two -CH3 groups present on the second carbon ..
Suppose that P is always completely dominant to any number of p's, and that the locus is close to the centromere. What is an expected ratio of purple:white in the progeny of the next crosses.
How, at what time the shoot tip touched the other plant's stem did the shoot switch from growing straight to growing in a spiral? Write down a hypothesis first.
How can altering ice nucleation protein production yield a bacterial strain useful to agriculture? Explain the logic and how this works.
Write down 1X4 matrices, P, G, and M that represent the nutritional values of each food. Then find 3P+2G+2M and tell what the entries represent.
Application of an insecticide to control mosquito populations in malaria infested areas quickly resulted in a dominant mutation, R, resulting in insecticide resistance.
What is an inspiratory capacity (IC) of a person with a tidal volume of 505 ml and an inspiratory reserve volume of 1950 ml? Is this person male or female.
Modern theory suggests that the early pre-life atmosphere on Earth was a reducing one. Why is it believed that oxygen was not present as life formed on Earth.
This Project report elaborates a critical review of important elements attached to Advanced Glycated End Products (AGEs). It is very crucial to understand the process called Millard reaction.
