The backbone of dna and rna is composed of . dna is double stranded due to interactions between adenine, cytosine, guanine, and thymine, which are . uracil is a

back bone of DNA deoxyribose and for RNA ribose

Yes DNA is double stranded because of interactions with adenine thymine cytosine and guanine which are nucleotide bases

uracil is a nucleotide base

-The backbone of DNA and RNA is composed of sugar and phosphate groups. The sugar is the 3' end, and the phosphate is the 5' end of each nucleotide in the DNA. In DNA, sugar is called deoxyribose, which is a cyclic pentose (5-carbon sugar). In RNA, sugar is a ribose.

- The nitrogen bases interact with each other. The two strands are held together by hydrogen bonds between the complementary bases, adenine with thymine, and cytosine with guanine.

- Uracil is a nitrogen base found only in the arn and is a pyrimidine that replaces the thymine base.
