What is the purpose of chromatin condensation?
Chromatin condensation is one of the vital processes occurring during spermatogenesis, in which most of sperm DNA histones are replaced by protamines to obtain a higher compaction and protection.
What happens when a chromosome condenses?
Chromosome condensation is the dramatic reorganisation of the long thin chromatin strands into compact short chromosomes that occurs in mitosis and meiosis.
Why do chromosomes condense during prophase?
Chromosomes condense during prophase because it makes them easier to separate into the two daughter cells.
Why is there a need of condensation of chromosome during prophase stage?
Chromosome condensation is one of the major chromatin-remodeling events that occur during cell division. The changes in chromatin compaction and higher-order structure organization are essential requisites for ensuring a faithful transmission of the replicated genome to daughter cells.
What is mean by chromatin condensation?
n. the first stage of mitosis or meiosis in cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes. [1880–85]
What is a condensed chromosome?
A highly compacted molecule of DNA and associated proteins resulting in a cytologically distinct structure.
Do chromosomes condense in meiosis?
Meiosis II is a mitotic division of each of the haploid cells produced in meiosis I. During prophase II, the chromosomes condense, and a new set of spindle fibers forms. … At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.
