Q. In a cell cycle the RNA synthesis needed in protein synthesis, occurs in

Cell Cycle and Cell Division

Solution:

The stage between two successive cell divisions is known as Interphase. In interphase, chromosomes are not condensed and are distributed throughout the nucleus. It is the largest period in the cell cycle and is divided into three phases - G1S and G2. During G1-phase (or post -mitotic phase), the cell grows and synthesis of RNA, ribosomes, enzymes and proteins necessary for DNA synthesis occurs. During S-phase or synthetic phase the replication of DNA occurs.For replication of DNA, histone proteins are required so they are also synthesized during this phase. It takes about 30%-50% of the total cell cycle. The nucleotides get assembled together and DNA molecules are synthesized. During G22phase (or pre-mitoticphase), nucleolar RNA, ribosomal RNA,messenger RNA are all synthesised.
