Concept explainers

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:

Question

When in the cell cycle does DNA replication occur?

M phase

G1 phase

S phase

G2 phase

G1 and G2 phase

Definition Definition Mechanism by which deoxyribonucleic acid (DNA) is capable of producing an exact copy of itself. DNA molecules utilize a semiconservative method for replication. DNA replication is the most essential part of biological inheritance and is crucial for cell division during growth and repair of damaged tissues.
