The interphase is the part of the eukaryotic cell cycle that is most transcriptionally active. Gene regulation during this phase involves changes in the chromatin. a) What is chromatin? b) How can the chromatin structure change?
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:
The interphase is the part of the eukaryotic cell cycle that is most transcriptionally active. Gene regulation during this phase involves changes in the chromatin.
a) What is chromatin?
b) How can the chromatin structure change?
DNA is the genetic material that transfers the information from one generation to the other. It is made up of chains of nucleotide polymer held together by hydrogen bonds. The two chains are antiparallel to one another and pairing occurs between thymine by two H-bonds with adenine and guanine by three H-bonds with cytosine.
