Cell Cycle (IPMAT)
-
G1: Cell growth. The cell size increases, protein synthesis occurs and organelles starts to duplicate.
-
-
DNA (double helix shaped genetic material that carry the genetic information. It is made up of nucleotides.
Chromatin: DNA is packed into chromatin (supercoil) when the cell is not dividing. It looks wool thread.
Chromosome: When the cell is dividing chromatin becomes chromosome and histone proteins pack up the DNA.
Nucleosome: When DNA is packed with histone proteins, nucleosomes are formed before they become chromosome.
Nucleotides: Have bases : A,T,G,C and Deoxyribose sugar (5c) and Phosphate group (H3PO4) A=T ,G makes 3 Hydrogen bonds with C. Bases have nitrogen in them.
Nucleus protects the DNA and the code for the cell division is given by DNA so Nucleus and DNA presence is very important for cell division.
Cancer
Benign
Cells keep dividing and form tumors but these tumors do not move to the other organs, they remain stable.
Malignant
Cell division is invasive and tumors make blood vessels and join the blood stream and move to the other organs.
Control
Check points (growth factors also help check point proteins. If they get damaged then cell cycle keeps going uncontrollably.
G1: Occurs toward the end of G1. Checks if the necessary proteins are synthesized. If not the cell goes to G0 phase.

Cell division: It occurs when the cell surface area/volume ratio increases. The cell needs to divide in order to continue its functions.
