In corn, the following allele pairs are on chromosome 9: colored (C) vs. white (c) aleurone color; starchy (Wx) vs. waxy (wx) endosperm; and full (Sh) vs. shrunken (sh) endosperm. F₁ plants heterozygous for all three alleles were test crossed; the resulting progeny had the following phenotypic ratios:

colored, waxy, shrunken 116

colored, starchy, full 601

colored, starchy, shrunken 2538

white, starchy, shrunken 4

white, starchy, full 113

white, waxy, full 2708

white, waxy, shrunken 626

colored, waxy, full _____2

6708

Determine the order of and distances between the three genes.  Also determine the coefficient of

coincidence (C) and the interference (I).

The undigested antibodies and pepsin digested antibodies were tested for haemagglutination. In the haemagglutination assay, the titre for undigested antibodies is 8 and pepsin digested antibodies is 4. why pepsin digested abs has lower titre compared to undigested abs. State 2 reason.

There are two ways to study receptor responsiveness in cultured cell lines: use a cell line that naturally expresses the receptor of interest; and transfect a cell line with a gene for the receptor you are interested in in order to ensure large numbers of this receptor. Taking into consideration what you know about G protein-coupled receptors and about measurement in pharmacology, briefly discuss what the possible advantage(s) and disadvantage(s) might be of each of these approaches.

Addison's disease develops when the adrenal cortex doesn't secrete enough mineralocorticoids and glucocorticoids. President John F. Kennedy was diagnosed with the disease when he was a young man. Before he started treatment with hormone replacement therapy, he was hypoglycemic and lost weight. Which missing hormone was responsible for his weight loss? How might Addison's disease have affected his blood pressure?

What is the name of the tissue lining the organs in the peritoneal cavity?

1. We know that an F+ cell can donate its F plasmid to a recipient cell to create a new F+ cell.

But what about an Hfr? Can an Hfr transfer its DNA as well? (yes/no) Please explain your answer. Why did you answer yes or no?

2. Let’s just assume,, that an Hfr cell could transfer DNA. What would the recipient cell look like? What would it be called? F+? F-? Hfr+? Something else altogether? Please explain your answer.

A group of scientists wants to determine if fin length variation is genetically or environmentally controlled. They think the presence of predator pressure may be an environmental determinant of fin length. The scientists take eggs from short-tailed parents and raise them in both low and high predator pressure environments. They also take eggs from long-tailed parents raise them in both low and high predator pressure environments. The scientists then evaluate the tail length of the fish hatched from the eggs at adulthood. Select the correct dependent variable for this experiment.

A.Level of predation pressure.

B.Tail length at adulthood.

C.Tail length of the parents of the eggs.

D.The eggs.

5. You have a dialysis bag containing 15-mL protein solution in 0.20 M NaCl. a. Would it be more efficient to dialyse this solution against i)one 2 L volume of buffer until equilibrium is reached, or to ii)dialyze the solution against one L buffer until equilibrium is reached, the remove the bag and dialyze against another one L of buffer til equilibrium is reached. Assume there is no volume change in the dialysis bag with dialysis. (1 pt) {type answer here } b. What is the concentration of NaCl left in the dialysis bag after condition i? What is the concentration of NaCl left in the dialysis bag after condition ii? (2 pts)
