Answer:

The correct answer is option a. "Double-stranded regions of RNA typically take on an B-form right-handed helix".

Explanation:

Most of the native double-stranded DNA is on an B-form right-handed helix, following the structure proposed by Watson and Crick with about 10–10.5 base pairs per turn. However, double-stranded RNA does not follow this structure, and most regions have an A-form structure. The A-form right-handed helix have slightly more base pairs per turn, which makes it 20-25% shorter than B-DNA.

Hi everyone

professor190 [17]

Amino acids are acids on one hand, and a base on the other hand.

An acid is a substance that produces hydrogen or hydroxonium ions as the only positively charged ion when it ionizes.

All amino acids have an amine group - $NH_2$ and a carboxylic group - $COOH$ .

The carboxylic group ionizes such that:

$COOH -- > COO^- + H^+$

The presence of the amine group enables amino acids to also act as a base.

Explain how a mutation is random process, but natural selection is not random?

Vinvika [58]
