Composed in the highly successful Methods in Molecular Biology(tm) series format, each chapter contains a brief introduction, step-by-step methods, a list of necessary materials, and a Notes section which shares tips on troubleshooting and avoiding known pitfalls. Comprehensive and cutting-edge, ...
The final step of meiotic division involves the decondensation of chromosomes and the reformation of the nuclear envelope around the chromosomes present at each pole of the cell. This newly formed nucleus now contains half the chromosome number as the original parent cell, becoming a haploid sex ...
Meiosis – A Source of Distinction Why do you share some but not all characters of each parent? What are the rules of this sharing game? At one level, the answers lie in meiosis. Meiosis does two things - 1) Meiosis takes a cell with two copies of every chromosome (diploid) and makes...
Meiosis is the generation of germ cells (eggs and sperm). In meiosis, DNA replication is followed by two division cycles: meiosis I, which segregates homologous chromosomes and meiosis II, which segregates sister chromatids. Thus, four daughter cells are generated that each contains one homologue...
in which the chromosomes will begin to decondense. In some organisms, the nuclear membrane will begin to reform, but this is not always the case. The final step of telophase is the actual division of the two cells into their respective daughter cells, each of which contains one set of chr...
Such an arrangement allows the attachment of each kinetochore to the microtubules of the spindle pole on the opposite side. This arrangement is the first step that sets for the separation of the chromosomes during the following anaphase. At this stage, the bivalents are randomly arranged, ...
A cell's life is composed of various stages with a distinct set of actions. This phenomenon is titled as the cell cycle. The cell cycle is composed of the stages G1, S, G2, and M. Each cell stage prior to the last stage M, which involves cell division, is a preparation step in...
Mitosis and meiosis are both processes of eukaryotic cell division, with the same names used to describe different stages. What are the significant cellular and chromosomal events that occur during each stage of mitosis? What stage and steps in meiosis are so important to the genetic variation wit...
