英语翻译原文:Process of MeiosisUnlike the single-cell division of mitosis,meiosis involves two cellular divisions:meiosis I and meiosis II.Each stage of meiosis runs through the same five stages as discussed in mitosis.During the first round
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...
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...
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...
Analysis of meiosis prophase I process in SPDYA-binding-deficient SUN1 mutant mice reveals that the SUN1-SPDYA interaction is required for the telomere-LINC complex connection and the assembly of a ring-shaped telomere supramolecular architecture at the nuclear envelope, which is critical for ...
of the “brown anther” type is blocked at a late stage of meiosis, and the stamens of the “petaloid” type produce no pollen. In carrot breeding, the “petaloid” type of male sterility is used more often. In 2018, Tan et al. found a wild petaloid male sterile carrot line (Wuye-...
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...
Owing to the lack of a precise ‘replication’ process for parental nucleosomes and to the loss of many DNA-binding factors and chromatin-associated components during mitosis and meiosis, the inheritance of single nucleosome marks poses specific challenges28. Mathematical modelling and biological evidenc...
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 ...
