WebChromosomes. Introduction. When a cell divides, one of its main jobs is to make sure that each of the two new cells gets a full, perfect copy of genetic material. DNA and genomes. Chromatin. Chromosomes. Chromosomes and cell division. WebM phase (Mitosis): Mitosis is the stage during which the visible events of cell division occur and the replicated chromosomes segregate to separate daughter cells. Mitosis is the type of cell division that makes a multicellular organism from a fertilized egg, replaces old cells, regenerates organs, and is a means of asexual reproduction for many organisms.

Once meiosis starts, the purpose is to produce a haploid gamete. So there is no further need of replication or growth. ... the cell's homologous chromosomes line up extremely close to one another. Then, the DNA strand within each chromosome ... WebIn meiosis, the chromosome or chromosomes duplicate (during interphase) and homologous chromosomes exchange genetic information (chromosomal crossover) during the first division, called meiosis I.
