The fastest rate of mitosis happens in the zygote, embryo and infant stage for humans and animals because mitosis is essential for embryological development. Mitosis is also required at a higher rate to grow and repair tissue. Some examples include human lymph nodes and bone marrow.

[5] [6] After growth from the zygote to the adult, cell division by mitosis allows for continual construction and repair of the organism. [7] The human body experiences about 10 quadrillion cell divisions in a lifetime. [8] The primary concern of cell division is the maintenance of the original cell's genome.
The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.
A few types of organisms, such as many fungi and the ciliate Paramecium aurelia, [11] have more than two "sexes", called mating types. Most animals (including humans) and plants reproduce sexually. Sexually reproducing organisms have different sets of genes for every trait (called alleles). Offspring inherit one allele for each trait from each ...

Endogenous mitogens function to control cell division is a normal and necessary part of the life cycle of multicellular organisms. For example, in zebrafish , an endogenous mitogen Nrg1 is produced in response to indications of heart damage.
Say you have a 4-year-old Labrador named Comet — with the new equation, Comet's real "dog age" would be slightly older than 53. The reason for the difference is actually pretty simple.
