Gene Vellow Pigment ,in some plants White By-product ENZYME Rabbits that have the active form of this gene produce white-colored fat. Rabbits who have the defective form of this gene produce yellow- colored fat. However, there is an environmental complication of this trait. (See the following questions.) 1. If a rabbit that has the active form of the gene is fed plants with the pigment, what color is its fat? 2. If a rabbit with the defective gene is fed plants with the pigment, what çolor is its fat?

2. Below, recognition sites of two of these enzymes, Pstl and Nsil, are given 5'... CTGC AG. 3... GACGTC...5 3 Pstl recognition and cleavage site 5... ATGCAT 3'... TACGTA ... 5' 3' ... Nsil recognition and cleavage site a. Does cleavage by Pstl result in a 5' or 3' overhang? What is the sequence of this overhang? b. Does cleavage by Nsil result in a 5' or 3' overhang? What is the sequence of this overhang? c. Suppose you have a cloning vector that contains a Pstl recognition site and you also have foreign DNA that was cut with Nsil. Can this DNA be ligated into the Pstl site of the vector, and if so, explain its reason and draw the new ligation site. d. Can the new ligated DNA segment sequence be cut from the vector with Pstl or Nsil ? What potential problems do you see?
Scale color in dragons is determined by two genes. The W gene is epistatic to the G gene. The W allele is dominant and allows the production of pigment, while w is recessive and blocks pigment formation, resulting in white dragons. When pigment formation is possible, the dominant G allele results in green dragon scales, while the recessive g allele results in black dragon scales. The pigment formation pathway is shown below W (Enzyme 1) G (Enzyme 2) White precursor Black intermediate pigment Green pigment а. What color scales would you expect in each of the following dragons? WwGg Wwgg WWGG wwgg b. If you cross two dragons with WwGg genotype, what is the expected phenotypic ratios of the progeny? c. What kind of epistasis do we observe?

1. Suppose there was a mutation in the inducer of the lac operon, such that the inducer was unable to function. How would the lac operon be affected? Please explain your reasoning in 1-3 sentences.
1. In a plant species, flower-colour is determined by the biochemical pathway shown below: E A D Colourless blue yellow purple red Genes A, B, C, D, and E are independently assorting. The dominant alleles A, B, C and D encode enzymes that catalyse the corresponding reactions indicated above. The recessive alleles a, b, c and d are non-functional and do not produce active enzymes. The dominant E allele totally inhibits the action of gene C, while the recessive allele e has no effect. a) Determine the F1 and F2 phenotypes from a cross between AAbbCCDDEE and AABBCCDDee plants. b) What proportion of the offspring of an AaBBCCDdEe x AaBBCcDdEe cross is expected to have coloured flowers?
traffic deaths in 10 years. Does daylight savings time increase the number of traffic deaths? (Many countries are in the process of getting rid of the time change - even though the Senate did vote to stop the time change the legislation seems to have stalled (as usual!)). 6) Epistasis is a phenomenon in which one gene controls the expression of another. In one case, a dihybrid cross should yield a 9:3:4 ratio. You collect the following data on mice: black coat: 218 Is there any reason to doubt the ratio of 9 black: 3 brown : 4 white? brown coat: 76 white coat: 89
Explain why Tyrosinase (TYR) plays a crucial role in the melanin biosynthesis pathway The gene encodes an enzyme called tyrosinase, which is responsible for oxidizing tyrosine.
