Question

The most common thing, between the webbed fingers and toes in humans and the development of cancer cells is

• A. Both are caused by excessive cell growth
• B. Both are caused by a loss of apoptosis
• C. Both are a result of exposure to carcinogenic compounds
• D. Both are caused by excessive fat-soluble vitamin levels
• E. Both are caused by infections from cancer-associated viruses

Answer 1

The correct option is B Both are caused by a loss of apoptosis

Apoptosis is programmed cell death. Webbed fingers and toes are abnormal conditions, caused by the absence of apoptosis at the 16${}^{th}$ week of gestation, that dissolve the tissues between fingers and toes. Apoptosis leads to removal of old cells and their replacement by new cells. The Lack of apoptosis causes uncontrolled cell proliferation and finally leads to cancer. So, the correct answer is option B.
