A cell in G1of interphase has 12 chromosomes. How many DNA molecules will be found per cell when this original cell progresses to the following stages? G2 of interphase? Prophase of mitosis? After cytokinesis following mitosis?

1. G2 of interphase

-12 chromosomes and 24 DNA molecules per cell.

2. Prophase of mitosis

-12 chromosomes and 24 DNA molecules.

3. After Cytokinesis following mitosis

-12 chromosomes and 12 DNA molecules per cell.

Explanation:

Meiosis is a unique type of division seen in cells which chromosome number is decreased to half with the formation of haploid cells. It can be called a reduction division and is majorly found in organisms that sexual reproduce.

1. G2 of interphase

G2 of interphase takes place after S phase, when the DNA molecules undergo replication to produce a chromosome of two DNA molecules. Hence, a cell in G2 possesses 12 chromosomes and 24 DNA molecules.

2. Prophase of mitosis

The chromosomes condense and observed to be seen, the centrosomes separates, and microtubule fibers is produced from the centrosomes. This cell will contain 12 chromosomes and 24 DNA molecules.

3. After cytokinesis following mitosis?

At this stage the daughter cells will proceed to G1. Each cell will possess 12 chromosomes and 12 DNA molecules.
