1.In which phase of the cell cycle are DNA mutations most likely to occur? A.S Phase B.G1 Phase C.G2 Phase D.Prophase 2.Which of the following contains all of the components of a nucleotide? A.Sugar, phosphate, base B.Sugar, amino acid, base C.Amino acid, phosphate, base D.Sugar, phosphate, amino acid
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:
