Option C
Due to excess cell division,cancer is caused.
It has to be identified at the initial stages ti prevent the spreading of it or to be cured early.
Mitosis occurs in Vegetative/Somatic cells.
Mitosis occurs in five phases. They are :-
•Prophase
•Metaphase
•Anaphase
•Telophase and
•Cytokinesis
Answer:
✔The answer is option (b) cancer.✔
Explaination:
Cell division or mitosis is normal process in a living cell, but sudden and abnormal mitosis in an organ will frequently result in Cancer.
✪ Causes of cancer:
When the process of mitosis becomes out of control (Abnormal Mitosis), It results in cancer. Mitosis is closely controlled by the genes inside every cell. Sometimes this control can go wrong. If that happens in just a single cell, it can replicate itself to make new cells that are also out of control. Cancers cells will form lumps or tumor that damage the surrounding tissues.
➪ Example :
The two genes called E6 and E7 of the 'Human Papilloma Virus', produce some of proteins. These protein displace the regulatory protein molecules that regulate cell division. This results in loss of cell division control and creats an uterine facial tumor.
★Hence, Cancer is not a disease. It occurs for abnormal mitosis.★
⍟ Abnormal Mitosis:
When a chromosome is abnormal , it can cause health problems in the body. Abnormal chromosomes most often happen as a result of an error during cell division. Chromosome abnormalities often happen due to the errors during dividing of sex cells or others cells.
