Question

An one page "elevator pitch" about Cell cycle

Answer 1

CELL CYCLE.

The cell cycle is a series of steps that take place in a cell that causes it to divide into two daughter cells.A cell spends most of its time in interphase (inactive phase) and during this time it grows ,replicates its chromosomes and prepares for cell division. The cell then leaves when interphase it undergoes mitosis and completes its division.

Phases of the Cell Cycle:-

1. Gap 1 phase ,G1
2. Synthesis phase ,S
3. Gap 2 phase, G2
4. Mitosis phase M

• During G1 phase the cells increas in size,produce RNA and synthesize protein.
• S phase is the phase of the cell cycle in which DNA is replicated which occur between G1 phase and G2 phase.
• Rapid cell growth and protein synthesis occurs at G2 phase during which the cell prepares itself for mitosis.
• During the M phase the cell divides its copied DNA and cytoplasm to make two new cells.It involves two division related processes like mitosis and cytokinesis.The phases of M phase includes:- Prophase:-In the nucleus,chromosomes condense and becomes vissible. Metaphase:-The copied chromosomes align in middle of the spindle. Anaphase:-Chromosomes seperate into two genetically identical groups. Telophase:-Nuclear membranes form around each of the sets of chromosomes. Cytokinesis:-The cell spilts into two daughter cells,with each same number of chromosomes as the parent.
