If the DNA sequence is CCAATTGA, what is the compliment?

Dvinal [7]

GGTTAACT is the complement of DNA sequence CCAATTGA.

<h3>What is a complement sequence of DNA?</h3>

A sequence of bases in a nucleic acid called a complementary sequence can be used to match base pairs to create a double-stranded structure. For instance, G-T-A-C is the complementary sequence to C-A-T-G, where each letter represents a different DNA nucleotide.

Every DNA sequence has a counterpart sequence running in parallel since DNA has two strands. Adenine (A) is always coupled with Thymine (T) in the complementary sequence, while Cytosine (C) is always paired with Guanine (G).

Natural complementary DNA plays a crucial role in the production of new DNA copies and has emerged as a key experimental tool. The two strands of DNA are unraveled from one another during replication. Each strand is replicated twice, one by a DNA polymerase molecule that runs the length of each strand.
