A cell will usually undergo apoptosis if the cell experiences dna damage that could lead to a tumor. Predict what may happen if a gene that controls apoptosis is damaged

P⁵³ gene called as tumor suppressor gene is responsible for apoptosis.

Explanation:

The protein which encodes the gene belongs to a family of protein that have 3 members P⁵³,P⁶³ and P⁷³.

P⁵³ is known as tumor suppressor protein that is responsible for apoptosis of cells.

This protein is encoded by TP53 gene.This is important and play a crucial role in cell cycle an thus functions as tumor suppressor which involved in preventing  cancer.Thus it is called called as "Guardian angel gene".

It not only function as anti cancer but also participate a crucial role in apoptosis,genomic stability and inhibition of angiogenesis.

It can also activate certain proteins that are which helps in DNA repair process.

If damage is beyond repair the cell will normally send itself into apoptosis, ensuring that it will not pass on its damaged DNA.
