Answer :
Answer: C) Complementary
Explanation: Two strands of DNA that bind to each other are known as complementary strands. They're complementary because the nitrogenous bases of their respective nucleotides are able to bind with each other using hydrogen bonds to form the double helix structure of DNA. Adenine binds with thymine, and cytosine binds with guanine. The complementary nucleotide pairs of two DNA strands allow them to bind together to form the double helix structure.
A codon is a trio of nucleotides that codes for a specific amino acid or signals a stop to protein synthesizing. A codon doesn't describe the relationship between two DNA strands.
A chromosome is a biological structure composed of tightly condensed DNA strands.
Transcription refers to a process were a complementary mRNA strand is made based on a protein-coding DNA sequence.
