Question

Draw a feedback loop depicting the role of oncogenes and tumor suppressor genes in cancer.

Answer 1

Answer:

Explanation:

A positive feedback loop takes places when when oncogenes are there because of mutation in the proto-oncogenes.

In this condition, the cells start multiplying uncontrollably.

Nothing can practically stop their growth.

Tumor suppressor genes in cancer make a negative feedback due to apoptosis in cells that can lead to a cancerous condition.

Therefore, Oncogenes happen due to the turning on of proto-oncogenes whereas tumor suppressor genes may cause cancer while they are turned off.
