D) It is a helix with three types of grooves: major, intermediate, and minor.

Question

Quizplus · Accepted Answer

B-DNA is a helix with two types of grooves: major and minor. The major groove is wider and provides more access to the base pairs within the DNA, while the minor groove is narrower and provides less access. This allows for proteins and other molecules to interact with specific base pairs and regulate gene expression.
