Which of the following describe how DNA and RNA are similar? Check all that apply.DNA and RNA both contain deoxyribose sugars.DNA and RNA both have adenine pairing with thymine.DNA and RNA both store and pass genetic information.DNA and RNA both participate in the expression of genes.DNA and RNA both contain adenine, guanine, and cytosine.DNA and RNA both have hydrogen bonds that link nucleotides.
Answer
A
DNA and RNA both contain deoxyribose sugars.
B
DNA and RNA both have adenine pairing with thymine.
C
DNA and RNA both store and pass genetic information.
D
DNA and RNA both participate in the expression of genes.
E
DNA and RNA both contain adenine, guanine, and cytosine.
F
DNA and RNA both have hydrogen bonds that link nucleotides.
Explanation
DNA and RNA both carry genetic information, and both are involved in gene expression, so C and D are correct. Both also contain adenine, guanine, and cytosine, making E correct. They differ in their sugars, and RNA uses uracil instead of thymine. Nucleotides are joined by covalent bonds; hydrogen bonds pair bases rather than link nucleotides.
