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...
6. A SEX VESICLE AT MEIOSIS An examination of testes containing cells at meiosis shows that the autosomes in many of the cells are at pachytene. A most striking first impression of these cells is that the nucleus contains, in addition to the pachytene autosomes, a large oblong body which...
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 ...
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 ...
The process of sexual differentiation is central for reproduction of almost all metazoan and therefore for maintenance of practically all multicellular organisms. In sex development we can distinguish two different processes: First, sex determination is the developmental decision that directs the undifferent...
Programmed DSBs followed by repair during meiosis facilitate shuffling of genetic information between homologous non-sister chromatids. However, a majority of these DSBs remain unrepaired and result in the formation of non-crossovers (NCOs). Three pathways that suppress meiotic recombination have been id...
However, the laborious process of protein engineering limits large-scale application of ZFPs and TALEs. A major breakthrough came from the advent of the CRISPR/Cas9 system, in which the Cas9 endonuclease can be targeted to specific DNA sequences by guide RNAs (gRNAs) that are easily ...
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...
