CELL CYCLE AND CELL DIVISION

IMPORTANT KEYS

Interphase , cell division, mitosis, mitosis prophase, metaphase, anaphase, telephase,cell cycle

POINTS TO REMEMBER

1.cell cycle involves gynome duplication synthesis of other cell constituents and division into two daughter cell
2.human cell divides once in 24hrs in active medium.
3.Interphase and multiplication are the two successive phases.
4.Interphase consists of G1 s and G2 phases.
5.DNA synthesis takes place in S phase.
6.Some animal cells exhibit division occasionally and enter into quiescent stage (GO) of cell cycle (Eg:nerve cells)
7.Somatic cells divide by mitosis. Mitosis can be happen in both diploid and haploid organisms.
8.Two process of cell division : Karyokinesis and cytokinesis
9.chromosomes with two sister chromatids attached to center centromese is visible in metaphase stage
10.Separated chromosome moves to opposite poles in anaphase stage.
11.Mitosis helps in cell repairing and growth.
12.Mitosis results in the formation of 2 diploid daughter cells.
13.Mitosis happens in germ cells to produce haploid gamales from diploid germ cells.
14.Two successive divisions such as Metosis I and Metosis II results in the formation of 4 haploid daughter cells.
15.Homologous chromosome pairing synapsis happens at Zygotene of Metosis I.

BIO CHEMICAL CO- ORDINATION AND INTEGRATION

“ Learning biology of today & applying it in medicine makes you the best future Physicians”

Robert Frost quotes in his poem “But miles to go before I sleep, I have promises to keep “. The study of biology is also a long journey which needs comprehensive and analytical mind to succeed in the Neet Bio exam .
Key to study Neet Biology
1. Comprehensive Reading
2. Listening capability
3. Concentration
4. Memorising concepts
5. Practice the series of test
