Question

select the three statements that correctly describe the differences between dna and rna. rna nucleotides contains uracil instead of thymine as in dna. dna consists of two strands of nucleotides while rna has one. dna nucleotide comprises deoxyribose sugar while rna consists of ribose sugar. rna consists of phosphate group while dna has nitrogenous group. dna nucleotides contain an adenine - uracil base pairing rna is more complex than dna because it has more types.

Explanation:

DNA has thymine, double - strand and deoxyribose; RNA has uracil, single - strand and ribose. Both have phosphate and nitrogenous groups. Adenine - uracil pairing is in RNA not DNA, and DNA is not less complex than RNA due to types.

Answer:

• RNA nucleotides contains uracil instead of thymine as in DNA.
• DNA consists of two strands of nucleotides while RNA has one.
• DNA nucleotide comprises deoxyribose sugar while RNA consists of ribose sugar.
