What is a frequency distribution? Explain how the graph is made for a quantitative trait that is continuous.
Explain the difference between a continuous trait and a discontinuous trait. Give two examples of each. Are quantitative traits likely to be continuous or discontinuous? Explain why
What is a normal distribution? Discuss this curve with regard to quantitative traits within a population. What is the relationship between the standard deviation and the normal distribution?
Most new mutations are detrimental, yet rare beneficial mutations can be adaptive. With regard to the fate of new mutations, discuss whether you think it is more important for natural selection to select against detrimental alleles or to select in favor of beneficial ones. Which do you think is more significant in human populations?
transcribe the following dna code from the nucleus to the mrna molecule
TAC - GGA - CAG - GCG - CCG - CAA - CGC -TAT - ACT
What evolutionary factors can cause allele frequencies to change and possibly lead to a genetic polymorphism? Discuss the relative importance of each type of process.
describe the nature strength and formation of the following types of chemical bonds and give example of the compound in which they each of them occur
(a) covalent bond
(b) Hydrogen bonds
(c) ionic bonds
you could describe the mechanism of drugs such as the statins, which inhibit the function of the enzyme HMG-CoA reductase and so reduce the synthesis of cholesterol in the body. You could report the manner in which the inhibitors interact with their enzyme target, if they are allosteric or competitive and what the result of that inhibition is to the cell. (Try to pick an alternative example to statins).
you could describe the metabolic process of the bacteria that is used during cheese making, indicating the type of respiration that is happening during the process and the chemical reactions necessary for the formation of lactic acid.
You come across a patient who is suffering from severe fever and flu. The person comes from a vicinity affected by COVID-19. Blood sample is taken from the patient and analyzed for a complete blood picture. The result shows an elevated level of neutrophiles in the blood. Based on this result only, is this patient suffering from COVID-19 or not? Support your answer with reasons.
