1.RNA is usually single stranded, while DNA is usually double stranded.
2.RNA contains uracil, while DNA contains thymine.
3,RNA is usually double stranded, while DNA is usually single stranded.
4.RNA contains thymine, while DNA contains uracil.
5.RNA doesn’t contain cytosine, while DNA doesn’t contain adenine.

Answer 1

Difference between DNA and RNA
DNA....
1 Double stranded structure.
2 Nitrogen base is thymine.
3 Pentose sugar deoxyribose sugar.

RNA.......

Answer 2

Answer:

the correct answer would be 1) RNA is usually single stranded, while DNA is usually double stranded. 2) RNA contains uracil, while DNA contains thymine.

Explanation: Rna has uracil while dna does not and rna is not double stranded like dna.
