Question

what are the main differences between rna and dna? select all that apply. rna contains sulfate groups instead of phosphate groups. the 5 - carbon sugar in rna is ribose instead of deoxyribose. rna has a nitrogenous base called uracil instead of thymine. rna is usually single - stranded, not double - stranded.

Explanation:

RNA has ribose - phosphate backbone, uses uracil as a nitrogenous base, and is usually single - stranded. DNA has deoxyribose - phosphate backbone, uses thymine, and is double - stranded. RNA does not have sulfate groups.

Answer:

B. The 5 - carbon sugar in RNA is ribose instead of deoxyribose.
C. RNA has a nitrogenous base called uracil instead of thymine.
D. RNA is usually single - stranded, not double - stranded.
