Question

A certain by-product of industrial chemical processes is suspected of causing cancer and birth defects in animals and humans. This molecule enters cells and binds to receptor proteins, which then enter the nucleus and attaches to the DNA to alter the pattern of gene expression. Based on this observation, the chemical by-product can be said to closely mimic the actions of what substance

Answer 1

Answer: Carcinogen

Step-by-step explanation:

Carcinogens are substances that are capable of inducing cancer (uncontrolled cell division) by altering the base composition of the cell DNA.

They often resembles the structure of the bases present in the receptor proteins so as to aid easy binding.

Thus, the substance mimics the action of a CARCINOGEN
