Question

cA cell in G1 of interphase has 12 chromosomes. How many chromosomes and DNA molecules will be found per cell when this original cell progresses to prophase II of meiosis

Answer 1

Answer:

Prophase II meiosis-chromosomes-6 and 12 DNA molecules per cell.

Explanation:

Meiosis is a unique type of division that occur in cells in which the chromosome number is decreased to half with the creation of haploid cells. It can be referred to as reduction division and it mostly occurs in organisms which go through sexual reproduction.

In prophase II , the nucleoli and nuclear membrane disappear.

The chromatids reduces in length to become short and thick .

The centromeres migrates to the polar regions and set the spindle fibres in place for the second meiotic division.

Therefore, at Prophase II of meiosis

The daughter cells are haploid. Its haploid cells should possess six chromosomes and 12 DNA molecules.
