Respuesta :

DNA and RNA base pairing is slightly different since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine. Uracil differs from thymine in that it lacks a methyl group on its ring.

Answer:

The correct answer is DNA uses deoxyribose and thymine whereas RNA uses ribose and uracil.

Explanation:

Both DNA and RNA are the nucleotide which acts as the genetic material in organisms. DNA is the genetic material present in almost all organism except few viruses where RNA is the genetic material.

Although both are nucleic acid they both show a few differences in their structure like:

1. Sugar- in DNA is deoxyribose (lacks OH at 2') while in RNA is ribose.

2. Nitrogenous bases- DNA has adenine, guanine, cytosine and thymine whereas RNA has all except thymine where uracil is used.

Thus, DNA uses deoxyribose and thymine whereas RNA uses ribose and uracil is the correct answer.
