Question
Chapter 26.2, Problem 1COMQ
Summary Introduction
Introduction:
Genes are the functional unit of hereditary, which are made up of DNA (deoxyribonucleic acid). The term gene was first coined and discovered by scientists William Bateson and Wilhelm Johannsen, respectively. The study of genes is known as genetics.

Why is it easier to manipulate embryonic stem cells to differentiate into various tissues than it is to manipulate a typical adult cell?
a.
As cells develop, signaling pathways can cause some genes to be turned off during development.
b.
Adult cells have different DNA content than do embryonic stem cells.
c.
Emybronic stem cells pose less of a threat for organ rejection as do an individual s own adult cells.
d.
It is no easier to manipulate emybronic stem cells to differentiate into various tissues than it is to manipulate a typical adult cell.
