WebAug 6, 2024 · Chromosome duplication occurs prior to the division processes of mitosis and meiosis. DNA replication processes allow correct chromosome numbers to be preserved after the original cell divides. A duplicated chromosome is comprised of two identical chromosomes called sister chromatids that are connected at the centromere region.

WebMar 1, 2024 · The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

WebFirst, draw an arrow and label it with the name of the process that must occur before mitosis, then draw and label a cell in each stage of mitosis. Be sure you show the correct number of chromosomes at each stage as well as the correct number of cells at the end of the process. 2. What kind of cells are produced by mitosis? WebMeiosis employs many of the same mechanisms as mitosis. However, the starting nucleus is always diploid and the nuclei that result at the end of a meiotic cell division are haploid. To achieve this reduction in chromosome number, meiosis consists of one round of chromosome duplication and two rounds of nuclear division.
