Question

you have studied mitosis in onion root tip cells it has 14 chromosomes in each cells.How many chromosomes will the cell have at G2 phase

Answer 1

Answer:

At the G2 phase of the cell cycle in onion root tip cells, the number of chromosomes remains unaltered. Each cell will still have 14 chromosomes.

Explanation:

The cell cycle has two phases- Interphase and M phase( Mitosis phase). The interphase has the G1, S and G2 phase where the cell prepares itself before division.

Although the DNA content is found to increase( gets doubled) during this phase due to the DNA replication taking place in the S( synthetic phase), there is no division and hence the number of chromosomes remains constant.
