SUMMARY
Cell division processes, specifically mitosis, ensure that daughter cells inherit identical genetic material from the parent cell, maintaining the same order and number of genes on chromosomes. During meiosis, however, homologous chromosomes undergo approximately 40 cross-overs, leading to genetic variation. Chromosomal rearrangements, such as translocations, primarily occur in response to double strand breaks, which are more prevalent in regions with long CG sequences. Enzymes play a crucial role in mediating gene exchange during these crossovers.
