NEET BIOLOGY

Detailed explanation-1: -Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators.

Detailed explanation-2: -Cancer is the result of unchecked cell division caused by a breakdown of the mechanisms that regulate the cell cycle. The loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Faulty instructions lead to a protein that does not function as it should.

Detailed explanation-3: -Disruption of normal regulation of the cell cycle can lead to diseases such as cancer. When the cell cycle proceeds without control, cells can divide without order and accumulate genetic errors that can lead to a cancerous tumor .

Detailed explanation-4: -Cancers, however, occur due to an alteration of a normal biological process-cell division. Cells that progress through the cell cycle unchecked may eventually form malignant tumors, where masses of cells grow and divide uncontrollably, then develop the ability to spread and migrate throughout the body.

Detailed explanation-5: -Overall, the cell cycle has many regulatory steps that are crucial to maintaining homeostasis inside of the cells during the replication of DNA and the division of cells. Mutation inside specific genes can lead to the loss of balance inside the cells, thus resulting in cancer growth.
