Question

Melanie is asked to list the complementary base pairings of a DNA sample in her lab. What is the MOST appropriate response she can give? Group of answer choices ST, RJ, CO, DI, SE RFLP and PCR chromosomes and genes AT, CG, CG, AT, CG

Answer 1

AT, CG, CG, AT, CG

Step-by-step explanation:

Deoxyribonucleic acid, known as DNA, is a double-stranded molecule that constitutes the genetic information of a cell. DNA is a nucleic acid made up of monomeric units called NUCLEOTIDE. In other words, DNA is a long chain of nucleotides. The nucleotides are four bases namely; Adenine (A), Thymine (T), Cytosine (C) and Guanine (G).

In the DNA molecule, one strand made up of nucleotides is paired to another strand containing complementary nucleotides. This means that the nucleotide bases of one strand of a DNA molecule is complementary to the bases of the other strand.

In this question, Melanie is asked to list the complementary base pairings of a DNA sample in her lab. Her best response will be the following: A-T, C-G, C-G, A-T, C-G. Note that, Adenine pairs with Thymine while Guanine pairs with Cytosine.
