Answer 1

Base pairing is specific, allowing the DNA sequence of one strand to be used to synthesize RNA. Base pairs are stabilized by hydrogen bonds, contributing to the stability of the DNA double helix. The specificity and stability are essential for DNA replication and function.

Step-by-step explanation:

Base pairing is specific, and thus the sequence from one strand of DNA can be used to synthesize RNA during the process of transcription. The base pairs are stacked inside the DNA double helix, with adenine pairing with thymine forming two hydrogen bonds, and cytosine pairing with guanine forming three hydrogen bonds. This stacking and bonding stabilize the DNA helix, facilitating its replication and the storage of genetic information. Base pairs are linked by hydrogen bonds, with adenine and thymine forming two, and cytosine and guanine forming three. The specificity of base pairing and its importance in biology is summarized by Chargaff's rules and the Watson and Crick model of DNA structure. Additionally, nucleotides are linked together by phosphodiester bonds forming the backbone of DNA strands.
