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:
What happens during metaphase 2?
Cell cycle may be defined as the process of several events by which a cell can duplicates its genomic content and can be divided into two or more daughter cells. Two main phases of cell cycle are M phase (mitosis phase) and interphase. During interphase, cell prepares itself for division by its growth and DNA duplication.
The interphase is divided into three phases. G1 (gap 1) phase which marks the period between DNA synthesis and end of mitotic phase. S ( synthesis) phase in which DNA synthesis occur. G2 (gap 2) phase that lies between the S phase and M phase.
