Chapter 9.2, Problem 3CC
Summary Introduction
To identify:
The stages of the cell cycle in which a chromosome consist of two identical chromatids
Introduction:
In cell cycle one cell will divide to form two new daughter cells. Cell cycle consistG1, S, G2, and M phase.
Chromosomes are present in the nucleus of the cell that contains genetic information in forms of gene. Human have 46 chromosomes (23 pairs of chromosomes). Each new cell consist the same number of chromosomes of its parent cell.
