Question

1. if a segment of one strand of dna has the base sequence of a-t-g-c-a, what would be the sequence of the complementary strand.

Explanation:

Step1: Recall base - pairing rules

In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C).

Step2: Determine complementary bases

Given the sequence A - T - G - C - A:

• For A, the complementary base is T.
• For T, the complementary base is A.
• For G, the complementary base is C.
• For C, the complementary base is G.
• For A, the complementary base is T.

Answer:

T - A - C - G - T
