Answer:
True
Step-by-step explanation:
Tumour-suppressor proteins can be regarded protein that it's action
alleviate the potential for cancer as well as tumor formation, through modulation of cell growth by negative regulation of the cell cycle or through promotion of apoptosis. Mutation dysregulation of tumour-suppressor proteins could result to unregulated growth of cell as well as tumour development. In humans, tumor suppressor which is known as p53 is been encoded by TP53 gene. Some of the mutations that is seen in TP53 gene has mutant form of p53 as result, and there won't be room for longer function in slowing down cell cycle, and this will result in the cell becoming cancerous. Though some mutant forms of p53 has the ability to have increased resistance of cell to anticancer treatments. This is known as gain-of-function mutation.
Therefore, Tumor suppressor proteins can assist in slowing down the cell cycle under appropriate conditions
