DNAemäspareihin

DNAemäspareihin refers to the complementary base pairs that form the rungs of the DNA ladder. Deoxyribonucleic acid (DNA) is a double helix structure composed of two polynucleotide strands. These strands are held together by hydrogen bonds between specific nitrogenous bases. In DNA, there are four types of bases: adenine (A), guanine (G), cytosine (C), and thymine (T). The principle of complementary base pairing dictates that adenine always pairs with thymine, and guanine always pairs with cytosine. This pairing is often represented as A-T and G-C. The consistent pairing of these bases is crucial for the accurate replication and transcription of genetic information. The hydrogen bonds between the base pairs, while individually weak, collectively provide stability to the DNA molecule. This specificity in pairing ensures that when DNA replicates, each strand serves as a template for the synthesis of a new, complementary strand, maintaining the integrity of the genetic code across generations of cells.
