Mitosis is how cells divide! Learn what happens in all the phases of mitosis: prophase, metaphase, anaphase, and telophase.
Molecular structure of DNA. Nucleotide. Nitrogenous base, phosphate.
Outcomes:
How homologous chromosomes separate into two sets. Prophase I, metaphase I, anaphase I, and telophase I.
Meiosis is a process that creates sex cells (gametes) with half the number of chromosomes of the parent cell. Meiosis has two stages: meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material (crossing over). In meiosis II, sister chromatids separate, creating four haploid cells.
