Verified step by step guidance1
Identify the base pairing rules in DNA: Adenine (A) pairs with Thymine (T) via 2 hydrogen bonds, and Cytosine (C) pairs with Guanine (G) via 3 hydrogen bonds.
Write down the given DNA strand sequence: 5'-ATCG-3'.
Determine the complementary strand sequence by pairing each base with its complement: A pairs with T, T pairs with A, C pairs with G, and G pairs with C.
Count the number of hydrogen bonds for each base pair in the sequence: for each A-T pair, count 2 bonds; for each C-G pair, count 3 bonds.
Sum the total hydrogen bonds from all base pairs to find the total number of hydrogen bonds formed between the two strands.
