Meiosis is a specialized type of cell division in which two rounds of chromosome segregation follow a single round of DNA replication. In diploid organisms, meiosis generates gametes with a haploid number of chromosomes. Both general cell-cycle regulators and meiosis-specific proteins bring about this...

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.
This reduction in genetic content is accomplished during a specialized cell division called meiosis, in which two rounds of chromosome segregation follow a single round of DNA replication. In preparation for the first meiotic division, homologous chromosomes pair and synapse, creating a context that ...
This lottery, is, as we know, a very expensive one, as a number of proteins have to be synthesized to conduct recombinational repair of an induced DSB. In fact, in the light of new findings on meiosis it seems that an additional cost has to be calculated, that of producing a big set...

Meiosis involves one round of DNA replication followed by two meiotic divisions, MI and MII [6], [9], [10], [11], [12]. Oocytes initiating meiosis contain two homologous copies of each chromosome, one inherited from each parent, each of which replicates to form two sister chromatids ...
作者: Xiwen Cai, Steven S. Xu 摘要: Meiosis includes two successive divisions of the nucleus with one round of DNA replication and leads to the formation of gametes with half of the chromosomes of the mother cell during sexual reproduction. It provides a cytological basis for gametogenesis and...
Each daughter cell nucleus contains only a haploid number of chromosomes. The formation of gametes haploid cells occurs in two rounds: Meiosis I and II, with DNA replication for one time only (at the S phase of interphase).How do you know if a chromosome is homologous? Our Expert shares ...
