Chapter 7, Problem 41P
Summary Introduction

a.

To determine:

The number of genes required to define the structure of the hemoglobin protein.

Introduction:

Hemoglobin is a protein present in the red blood cells, which carries oxygen to the body tissues. It forms a reversible and unstable bond with the oxygen atom. Adult hemoglobin consists of a multimeric protein with four polypeptides. Two of the peptides consist of two units of alpha globin, with two units of beta globin.

Summary Introduction

b.

To determine:

The different types of hemoglobin protein that would be found in a person’s red blood cell and their proportion if a person is heterozygous for wild-type alleles and the allele that would yield amino acid substitution for both α-globin and β-globin.

Introduction:

Hemoglobin is a globular protein with a quarternary structure. Hemoglobin contains four globular chains. Each of the globular chains is wrapped around the heme group. Each heme group has iron in it, which gives hemoglobin the ability to bind oxygen atom to it. There are various isoforms of globin. The common isoforms are alpha, beta, gamma, and delta.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
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.
