Does mitosis occur in somatic cells? Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of...
Human sex cells precisely comprise 23 chromosomes, hence gametes have half the diploid number of the human somatic cells. Two cells after fertilization fuse forming a zygote now with two sets of chromosomes. Then the zygote develops to grow through mitosis. This chromosome number of 46 in humans...
2014). However, SIM investigations cannot determine the absolute number of molecules. The specific number and localization of proteins are required to understand their function in the chromatin organization of interphase nuclei and during cell divisions. Moreover, these data are necessary to improve ...
Moreover, the minimum value in the Adult 1–3 and Senile groups is even less than that in Children, suggesting that the low-copy cells are produced from high-copy parental cells rather than retained through a series of cell divisions in a minor fraction of subjects who have avoided strong ...
