Duplex DNA, simply put, is a double-stranded molecule of DNA.
Understanding Duplex DNA
The structure and function of duplex DNA are crucial to understanding genetics and molecular biology. Here's a more detailed explanation:
- Double-Stranded Structure: As the name suggests, duplex DNA consists of two strands intertwined to form the iconic double helix.
- Hydrogen Bonding: These two strands are held together by hydrogen bonds. These bonds form between specific nucleotide bases. According to the provided reference, the nucleotide pairings are Adenine (A) with Thymine (T), and Cytosine (C) with Guanine (G).
- Genetic Information: The sequence of nucleotides along these two strands encodes the genetic information. In other words, the order of A, T, C, and G determines the instructions for building and maintaining an organism.
- Stability: The double-stranded structure and the specific base pairing rules (A-T and C-G) contribute to the stability of the DNA molecule.
