Chemotherapy against Cancer

 — How chemotherapy work in stopping cancer cells

•     In chemotherapy medicines there are nucleotides are use which has similar structure as the natural nucleotides A, G, C and T.
• —  The A, T, G and C are nucleotides are present in the cell (cytoplasm).
•  —  Within the cell there is a nucleus in which the   nucleotides and other essential substances which are necessary for DNA replication are presents.

—  Because uncontrolled growth of cell is cancer its mean during uncontrolled growth cell divide rapidly and the DNA replication process become fast in cancer cells.

•    Because replication process become fast and more nucleotides used for DNA replication.
•     In cancer treatment when chemotherapeutic drugs used the cancerous cells used those nucleotides which have similar structure to the real nucleotides of the cell but not real nucleotides.

— HOW THESE NUCLEOTIDS HELP TO STOP THE GROWTH OF CANCER CELLS?

• —        The answer of this question is that one time during DNA replication when DNA used these nucleotides of drug instead of real nucleotides of cell than DNA replication stop in the cells.

— HARMFUL EFFECTS OF USES OF CHEMOTHEROPUTICAL DRUGS.

• —     These drugs which are used against cancer have positive effects as well as have negative effect.
•  —  As it helps to controlled the growth of the cancer cell it also stop the the growth of the normal cell.
