Question

If one strand of DNA has the sequence 5'ATCG 3', what would be the sequence of the matching DNA strand

Answer 1

3' TAGC 5'

Step-by-step explanation:

A-T, C-G

Answer 2

Each strand is made up of a sequence of four nucleotides, A, C, G, and T. The order of the nucleotide sequence encodes genetic information. Since the nucleotides pair in a predictable way — A with T, and C with G — each strand of the DNA is always complementary to the other.
