G-C pairing

G-C pairing refers to how guanine (G) and cytosine (C), two of the building blocks of DNA, stick together. They form a stable bond through three hydrogen bonds, which are weak attractions that hold the molecules in place. This pairing helps maintain the DNA structure, ensuring genetic information is accurately stored and replicated. The specific G-C pairing is crucial because it contributes to DNA’s stability and influences how genes are expressed and copied during cell processes.
