RNA and DNA are similar because: a. both contain the sugar deoxyribose b. they are both composed of nucleotides c. both contain the nucleotide Uracil d. they are both always double-stranded helices

Respuesta :

b, both are made of nucleotides.

Explanation:

A- deoxyribose sugar is found in DNA, while ribose sugar is found in RNA.

C- Uracil is used in place of thymine. uracil is found in RNA, thymine is in DNA.

D- RNA is made up of a single strand, while DNA is made up of double helix.
DNA and RNA are similar because they are both composed of nucleotides
