Chromatids And Meiosis Research Paper

Chromatin, chromatids, and chromosomes have different transformations in terms of mitosis and meiosis. Chromatin in Meiosis and Mitosis are shown differently in Interphase. In Mitosis, the chromatin is made up of DNA and proteins. The DNA coils around the protein and that structure is called a nucleosome. Each chromatid in Mitosis is made up of many strings of the DNA and proteins (nucleosomes) to form a half X. The chromosome is made up of two of the chromatids (DNA and proteins-nucleosomes) to form one X. Chromatin in Meiosis are made up of chromatids. Before meiosis I begins, each chromosome is duplicated or copied. Each half of a duplicated chromosome is the chromatid. In body cells, most chromosomes are found in pairs that have the same size and structure. These homologous chromosomes carry the same genes, but a pair of them may have different versions of the genes they carry. One chromosome pair is made up of sex chromosomes, which control the development of sexual characteristics. They are called X and Y characteristics in humans. Cells with a pair of every chromosome are called diploid cells. Sex cells are needed to keep chromosome number duplication from happening. Gametes are sex cells that contain half the usual number of …show more content…
During Meiosis, chromosomes are copied once, and the nucleus divides twice, hence Meiosis I and II. Also, during Mitosis, the chromosomes are copied once as well, but the nucleus divides only once. The cells that are produced by the process of Meiosis contain only half of the genetic material of the parent cell: one chromosome from each homologous pair and one sex chromosome. The cells produced by the process of Mitosis contain exactly the same genetic material as the parent: a full set of homologous chromosomes and one pair of sex
