 Complementarity (molecular biology)

In molecular biology, complementarity refers to the specific pairing relationship between nucleotides in DNA and RNA, and between the bases in these nucleic acids. This concept is crucial for understanding how genetic information is stored, replicated, and expressed. 1. **DNA Base Pairing**: In DNA, the bases adenine (A) and thymine (T) pair together, while cytosine (C) and guanine (G) pair together.
