Meiosis as a Process of Division of DNA Into Gametes

I am researching the structure of DNA, but can not understand how meiosis allows DNA to be divided into gametes.

Solution Preview

Meiosis is a type of cell division that leads to the formation of haploid gametes from diploid cells. During this process, the number of chromosomes present in the gametes gets reduced to half of its original number that is present in normal somatic cells. During meiosis, the homologous chromosomes present in diploid cells get separated. In case of human beings, the sperm and ova contains 23 haploid chromosomes, whereas the somatic cells contain 46 diploid chromosomes. This difference plays a vital role during the process of fertilization. The diploid somatic cell with 46 chromosomes in humans produces haploid sperm or ova with 23 chromosomes during gametogenesis. Fertilization leads to the formation of zygote with 23+23 haploid sets, which results in 46 chromosomes. Mitosis and cell differentiation leads to the formation of a new individual with 46 chromosomes in all the somatic (body) cells.

During interphase, the gametocyte grows and matures until the necessary hormone level is reached to stimulate gamete production. Then DNA replication occurs giving rise to joined chromatids which are prepared to start with the process of meiosis. During Interphase I, the cell will complete the process of replication of genetic material (DNA). The process of Meiosis is ...
