Question

I C C You have studied mitosis in onion root tip cells. It has 16 chromosomes in cach cell. Can you tett how many I chromosomes will C the cell have at G phase, after S phase, and after M phase? 1 Also, what will be the DNA content of the cells at G,, after s I and at G, if the i content after M phase is 2C? S​

Answer 1

Answer:

yes. it's the correct answer

Answer 2

Explanation:

It is given that the number of chromosomes present in each onion root tip cell is 16. Hence, the number of chromosomes in the cell will be 16 at G

1

phase, after S phase and after M phase. Also, if the DNA content after M phase is 2C. Hence, the DNA content at G

1

phase will be 2C. It will be 4C after S and G

2

phase.
