1.part of the process of gamete formation in sexual reproduction consisting of chromosome conjugation and two cell divisions after which the chromosome number is reduced by half. Comparemitosis. 2.expressive understatement, esp. litotes. [1580–90; < Greekmeíōsisa lessening =meiō-,variant s. ...
4.2.3 Outline the process of meiosis, including pairing of homologous chromosomes and crossing over, followed by two divisions, which results in four haploid cells. Meiosis involves two divisions. Meiotic cells have an interphase stage before the start of meiosis I which is similar to mitosis. It...
Meiosis involves two nuclear divisions: the first, reductional division is preceded by a long interphase and characterized by a complex and lengthy prophase I, during which the two homologous chromosomes (one from each parent) pair and synapse, the synaptonemal complex (SC; see below) is formed...
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 of division,two intermediate daughter cells are produced....
DNA sugar radicals may lead to the formation of altered sugars which may consequently lead to strand breaks at the sugar-phosphate backbone of DNA [33]. Free radicals are also involved in the formation of DNA-protein crosslinks, in which one DNA radical and one protein radical are involved [...
Meiosis is the two-step series of specialized cell divisions that makes sexual reproduction possible. Meiosis produces haploid cells, which contain just one member of every chromosome pair characteristic of an organism. In all animals, specialized cells in the reproductive organs, called germ cells, ...
Meiosis can be contrasted with mitosis, which is a process of cell division, whereby nuclei divide into two after the cell duplicates its chromosomes. Mitosis involves one cell division resulting in two identical diploid cells. The purpose of mitosis is to enable cells to contribute to the growth...
maturation division, a method of cell division by which the number of chromosomes is reduced by half, each diploid cell (containing two sets of chromosomes) giving rise, after two rapidly successive divisions, to four haploid cells (containing one chromosomal set each). The diploid number of chr...
The differences between them are summarized in Table 1. Table 1: Main differences between meiosis and mitosis MeiosisMitosis Produces haploid cells (n) Produces diploid cells (2n) Includes two nuclear divisions Includes one nuclear division The product is a gamete cell The product is a somatic ...
It is a type of cell division that results in the formation of gametes, such as sperm and eggs, which are essential for sexual reproduction. Meiosis involves two consecutive divisions, known as meiosis I and meiosis II, and is characterized by a unique set of events that ensure genetic ...
