Question

a major difference between dna and rna is (1 point)
○ only dna contains sugar
● only rna contains guanine
○ only dna is double - stranded
○ only rna has deoxyribose

Explanation:

Both DNA and RNA contain sugar. DNA has deoxyribose and RNA has ribose. Both DNA and RNA contain guanine as one of their nitrogen - containing bases. DNA is typically double - stranded while RNA is usually single - stranded. DNA contains deoxyribose, not RNA.

Answer:

C. Only DNA is double - stranded
