Chapter 12, Problem 10P
Summary Introduction

To explain: The Ura3 based selection identifies cells with defects in components required for import into the mitochondrial matrix.

Concept introduction: Ura 3 gene is involved in pyrimidine biosynthesis. Ura 3 gene produces an enzyme called Orotidine 5'-phosphate decarboxylase. Orotidine 5'-phosphate decarboxylase catalyses the decarboxylation step of orotidine monophosphate (OMP) to give uridine monophosphate(UMP) during pyrimidine biosynthesis. Uracil biosynthesis occurs in the cytosol.

Summary Introduction

To explain: The reason why the normal cells with modified Ura3 gene doesn’t grow in the absence of uracil.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb?  Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
Design a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity. Include the experiment, a control, and an interpretation in your answer.
The Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows: aabb: yellow AABB, AABb, AaBb, and AaBB: red AAbb and Aabb: orange aaBB: yellow aaBb: ? Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why?   Question 21 options:   orange because A is epistatic to B   yellow because A is epistatic to B   red because B is epistatic to A   orange because B is epistatic to A   red because A is epistatic to B   yellow because B is epistatic to A
