39 chromosomes involve at the cell poles as a result. They decreases from 2n (diploid) to n (haploid). They then go through meiosis II, results in 4 haploid daughter cells, with half several chromosomes as the parent cell.

G2 Checkpoint: What is it?

When DNA is broken, the G2 checkpoint prevents cells from initiating mitosis, giving the chance for healing and limiting the reproduction of damaged cells. Understanding the molecular origins of cancer requires a focus on the G2 checkpoint since it helps to the creation of genomic stability.

What is meiosis?

A single cell splits twice during the meiotic process, leaving four cells with half of its original genetic material. These cells—sperm in men and eggs in women—are our sex cells.

What is fertilization?

Fertilization is the combination of a haploid male gamete (spermatozoa) and a haploid female gamete (ovum) to create a diploid cell, the zygote.
