Acancer drug is being tested, and it is found that although the cancer cells can divide, the nuclear envelope cannot re-form. it is determined that a protein substance is sequestered so that it cannot be polymerized into the necessary structure. what is the most likely protein target of the drug?

a. β-tubulin
b. α-tubulin
c. lamin
d. keratin
e. actin

C. Lamin

Explanation:

Lamin is one of the most important proteins that form the nuclear envelope. These fibrous proteins are mostly present in the inner nuclear membrane and have a structural function in the cell.

If this protein is targeted, the nuclear envelope will not be able to reform, which would lead to the death of the cell.

answer: the answer is b
