Chapter 11, Problem 25P
Summary Introduction

To determine:

The type of cell division that is represented in the figure and the relationship between the parts of figure.

Introduction:

Meiosis, also known as the reductional division, is the second type of cell division that takes place in eukaryotes. The cell division is marked by a decrease in the chromosome number to half. This type of cell division allows the recombination of the genes on the chromosome to produce a zygote. The two diploid cells undergo division to produce four haploid daughter cells.

Summary Introduction

To determine:

The difference between cohesion of centromeres and cohesion of arms.

Introduction:

The chromosomes are condensed structures that are formed during the early phases of cell division from the loose network of chromatin thread and then regain their original structure after being divided into daughter cells.

Summary Introduction

To determine:

The mechanism that keeps the chromosomes together during metaphase.

Introduction:

The human consists of 23 pairs of chromosomes, condensed form of chromatids which divide during cell division into daughter cells. The human has 22 autosomes and one pair of sex chromosomes. The sex chromosomes determine the sex in an individual based on the type of sex chromosomes that are present in the fusing gametes.

Summary Introduction

To determine:

The role of shugoshin and the enzyme it inhibits.

Introduction:

The chromosome from chromatids are formed through the process of supercoiling. The chromatin fibres are condensed into thick structures called the chromosomes. This chromosome in bacteria is circular whereas in eukaryotes it is linear.

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.
