Why do so many tumor viruses encode proteins that localize t

Why do so many tumor viruses encode proteins that localize to the mitochondria?

a. To route ATP production to support the virus life cycle.

b. To inhibit the immune system from killing virus infected cells.

c. To stimulate ATP production to promote metastasis.

d. To block or override death signals so infected cells could survive.

Solution

Option B is correct. Because mitochondria is very important for innate immune system and apoptosis of virus infected cells. That is why many tumors viruses encode proteins that localise to the mitochondria.
