What critical event occurs during the S phase of the eukaryoticcell cycle?a. Cells make a decision of whether or not to divide.b. DNA replication produces pairs of sister chromatids.c. The chromosomes condense.d. The single nucleus is divided into two nuclei
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:
