Question

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

Explanation:

Ultraviolet rays are a type of mutagen. They can cause damage to DNA, which in turn can disrupt the normal progression of the cell - cycle as the cell may need to halt the cycle to repair the damaged DNA or may enter an abnormal cell - cycle if the damage is not properly repaired. Water is a normal component of cells and is not a disruptor. Proteins are involved in normal cell - cycle regulation rather than disruption. DNA is the genetic material that the cell - cycle is centered around, not a disruptor of it.

Answer:

B. Ultraviolet rays
