The following points highlight the four major phases of the cell cycle. The phases are: 1. G1 (gap1) phase 2. S (synthesis) phase 3. G2 (gap 2) phase 4. M (mitosis) phase. Cell Cycle: Phase # 1. G1 Phase: The G1 phase is set in immediately after the cell division. It is characterised by a change in the chromosome from [...]
The following points highlight the five main classes of chemical compounds in chromatin. The classes are: 1. Nucleic acids 2. Basic proteins or histones (protamines in sperm nuclei of some fishes and birds) 3. Acidic proteins (Non-Histones) 4. Lipoproteins 5. Associated inorganic molecules. Chemical Compounds in Chromatin: Class # 1. Nucleic Acids: The nucleic acids are of two types: (i) [...]
