Which of the Following Represents Base Pairing

Question

Which of the following represents base pairing?
A) CCGTTACTG
B) Sugar-phosphate, sugar-phosphate, sugar-phosphate
C) Ribose-deoxyribose, ribose-deoxyribose, ribose-deoxyribose
D) A-T, T-A, C-G, A-U

Accepted Answer

Base pairing refers to the hydrogen bonding between nucleotide bases in DNA and RNA. The base pairs in DNA are A-T (adenine-thymine) and C-G (cytosine-guanine). The base pairs in RNA are A-U (adenine-uracil) and C-G (cytosine-guanine). Choice D lists the correct base pairs for DNA (A-T and C-G) and also includes the incorrect base pair for RNA (A-U).
