Question

2 which of the following may disrupt the cell cycle? a water b ultraviolet rays c protein d dna

Explanation:

Ultraviolet rays are mutagens. They can damage DNA, which in turn can disrupt the normal progression of the cell - cycle as the cell has to pause or repair the damaged DNA. Water is a normal component of the cell environment and is not a disruptor. Proteins are essential for the cell - cycle but are not a disrupting factor in normal circumstances. DNA is the genetic material and is involved in the cell - cycle but is not a disruptor by itself.

Answer:

B. Ultraviolet rays
