The role of cohesin is toa. make chromosomes more compact.b. allow for the replication of chromosomes.c. hold sister chromatids together.d. promote the separation of sister chromatids.
Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
The role of cohesin is to
a. make chromosomes more compact.
b. allow for the replication of chromosomes.
c. hold sister chromatids together.
d. promote the separation of sister chromatids.
Condensin and cohesin are two most important multiprotein complexes that help the chromosomes to segregate and align. These complexes are used for the chromosome compaction and to organize them into pairs. They both carry out structural maintenance of chromosomes proteins (SMC).
