Question

You have studied mitosis in onion root tip cells. It has $14$ chromosomes in each cell. Can you tell how many chromosomes will the cell have at $G_{1}$ phase, after S phase, and after M phase? Also, what will be the DNA content of the cells at $G_{1}$ , after S and at $G_{2}$ , if the content after M phase is $2$ C?

Solution

At G1 it will have 14 chromosomes
At S also it will have 14 chromosomes
G2 also has 14 chromosomes
After M phase 7 chromosomes
