Metacentric chromosomes have a centromere located: A. near the middle of the chromosome (chromosome has two arms of approx. equal length) B. towards one end (chromosome has one long arm and one short arm) C. near one end of the chromosome (chromosome has one long arm and a knob at the other end)
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:
