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...
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?
cytokinesis- organic process consisting of the division of the cytoplasm of a cell following karyokinesis bringing about the separation into two daughter cells karyokinesis- organic process consisting of the division of the nucleus of a cell during mitosis or meiosis ...
2.nature considered as the source of growth and change. 3.something that grows or develops. plagiotropism the tendency of some plants to diverge from the vertical in their growth. —plagiotropic,adj. polyeidism the passing of an organism through several different forms in the growth process. ...
Cytogenetic analysis revealed a compact karyotype, with 2n = 8♀/9♂, and half of the genome forms a pentavalent (Figure 1a) during male meiosis [24]. The chromosome 4 pair has been shaped by several large chromosomal events. First, one copy experienced a centric fusion to the regular X ...
(~5% of all stages; Fig.5d). In vivo, zygotes and various intermediates of meiosis with one, two and four nuclei were readily observable and these post-fertilization stages accounted for 35% of all parasites (Fig.5e). As these stages mature, they grow and their size significantly exceeds...
Crossing over, the process of the exchange of homologous regions between two copies of the genome at one of the stages of meiosis, ensures the random redistribution of genomic errors between gametes. An important property of this process is the significantly different from zero probability of ...
The 3D organization of chromatin modulates biological processes such as transcription, DNA replication, cell division and meiosis, which are crucial for cell differentiation and animal development. In this Review, we discuss recent progress in our understanding of the general principles of chromatin ...
