Chapter 12, Problem 17P

Summary Introduction

a.

To determine:

The reason duuue to which X chromosome will convert into Barr body.

Introduction:

The process of DNA replication is the process by which the genetic material of the organism copies itself to be distributed among the daughter cells during cell division. The DNA replication takes place before the cell division and prepares the cell for mitosis and meiosis. This process is followed by transcription and translation.

Summary Introduction

b.

To determine:

The explanation for interference in the expression of Xist present on the same chromosome as Tsix.

Introduction:

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

Summary Introduction

c.

To determine:

The role of Tsix knowledge in inactivation of the X chromosome by heterochromatization.
