Question

what strand of dna matches

Explanation:

Step1: Recall DNA base - pairing rules

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

Step2: Compare the given DNA strand

The given DNA strand is 5'-TGTAGCTGCCGT-3'. We need to find the complementary strand. The complementary strand will have bases according to the base - pairing rules.
The complementary bases for TGTAGCTGCCGT are ACATCGACGGCA.

Answer:

The strand that matches (complementary) to TGTAGCTGCCGT is ACATCGACGGCA.
