Mitosis is a process that occurs during thecell cycle.The role of mitosis in the cell cycle is to replicate the genetic material in an existing cell—known as the “parent cell”—and distribute that genetic material to two new cells, known as “daughter cells.”In order to pass its genet...
it seems clear that the resolution of fundamental problems associated with plant growth and development will require an understanding of the processes of expansion, division, and differentiation at the cellular level. Nevertheless, it is
Regeneration often involves the formation of a blastema, an outgrowth or regenerative bud formed at the plane of injury where missing tissues are produced. The mechanisms that trigger blastema formation are therefore fundamental for regeneration. Here, w
Ageing research has focused on lifespan-extending pathways in model organisms. This has led to the identification of several pathways that impinge on the ageing process, fortifying a multifactorial hypothesis to explain the underlying causes of organismal ageing.

In the ascus, two haploid nuclei generally fuse to make a diploid which undergoes meiosis to form four haploid nuclei; these then divide by mitosis resulting in eight nuclei, which form the basis for most ascospore development. The number of ascospores is characteristic for both the genus and ...
However, at the beginning of cell division (prophase), the nucleolus begins to dissociate, and then nucleoli reappear at the end of mitosis (telophase) [28]. The maximum number of nucleoli per nucleus depends on the maximum number of NORs present in a genome, which is 10 in human cells ...
Somatic cells—that is, the cells in your body that aren’t sex cells—do this via a process called mitosis. New sex cells, or gametes, are produced via a different process, called meiosis. Today, we’re going to talk about both of these. How are they different? How are they similar...
Somatic metazoan cells divide via the process of mitosis with high fidelity to generate two daughter cells that contain the correct complement of chromosomes. The ubiquitous molecular motor cytoplasmic dynein 1 (referred to henceforth as “dynein”) mediates several important mitotic processes1,2,3,4...
