Question

the diagram shows a single strand of dna. ? gacggcttaagatgc what is the complementary dna sequence for the strand? ctgccgaattctacg gacggcttaagatgc agtaatccggagcat tcattagg cctcgta

Explanation:

Step1: Recall base - pairing rules

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

Step2: Find complementary bases

For the given DNA strand GACGGCTTAAGATGC, the complementary bases are:
G→C, A→T, C→G, G→C, G→C, C→G, T→A, T→A, A→T, A→T, G→C, A→T, T→A, G→C.
The complementary sequence is CTGCCGAATCTACG.

Answer:

CTGCCGAATCTACG
