(Summary) Brooks Biological Principles Exam 3 Latest 2024 Solved 100%. Mitosis • the duplication and division of the nucleus • results in clones with no variation or adaptation • takes place in somatic cells (non-sex cells) • starts with one cell and creates 2 identical daughter cells • replicated chromosomes are evenly divided so that each daughter cell receives a complete set (46 chromosomes) • can occur by itself, but usually involves cytokinesis • not synonymous with ...
