Explanation: Cell division by mitosisoccurs in all human body cells except the gonads (sex cells). During mitosis, the DNA is exactly copied and a new daughter cell created with the same number of chromosomes as the parent cell, ie 46. Why does meiosis occur in humans? Meiosis only occurs...

Mitosis does occur in adult cardiac myocytes.Reports that a study has challenged the long standing belief that adult ventricular myocytes are terminally differentiated cells and therefore incapable of division, by revealing that mitotic division occurs in healthy and diseased hearts. Details of studies ...
Does meiosis occur in all cells at least once? (a) Are cells haploid or diploid during telophase? (b) Does this occur in meiosis? One replication of chromosomes followed by two subsequent divisions occurs: a. in meiosis. b. in mitosis c. in both meiosis and mitosis. d. in cytokinesis....
During the cell cycle, when does mitosis occur? When and where does meiosis occur? Where in the body does mitosis occur? How about meiosis? When, where, and why does mitosis occur in multicellular organisms? What are the stages of mitosis?
In What Type of Cells Does Mitosis Occur? Most of the cell division taking place in living organisms happens in somatic (non-reproductive) cells through mitosis. For instance, the human body sheds and replaces up to 40,000 skin cells per day, according to theAmerican Academy of Dermatology....
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...
ACCORDING to the Lyon hypothesis the somatic cells of female mammals are functional mosaics with the X chromosome of maternal origin active in some cells and the paternal X active in the remainder1. Lyon also postulated that inactivation of X chromosomes

A normal cell replicates and divides into two cells which in turn divide into four daughter cells and so on by DNA replication in mitosis. As the cell grows old, it dies because of the programmed cell death known as apoptosis. The dead cells are then replaced with new cells. However when...
