onsider the following statements about polytene chromosomes. Which are true? More than one answer is correct. Options: Polytene chromosomes and normal chromosomes contain the same amount of DNA, but the former are much larger because they contain large quantities histones. Polytene chromosomes are circular. Puffs on polytene chromosome puffs are sites of active protein synthesis. Polytene chromosomes are found in interphase. Puffs on polytene chromosome puffs are sites of active RNA synthesis.
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:
