DNSbázispár

DNSbázispár refers to the fundamental unit of the deoxyribonucleic acid (DNA) double helix. It consists of two nitrogenous bases, adenine (A) and thymine (T), or guanine (G) and cytosine (C), that are paired together by hydrogen bonds. In DNA, A always pairs with T, and G always pairs with C. This specific pairing, known as complementary base pairing, is crucial for the structure and function of DNA. The sequence of these base pairs along the DNA strand encodes genetic information. The sugar-phosphate backbone provides structural support, while the base pairs form the rungs of the DNA ladder, holding the two strands together. The order and number of these base pairs determine the unique genetic makeup of an organism. Understanding base pairing is essential for comprehending DNA replication, transcription, and the genetic code.
