20 lip 2020 · Although DNA is the genetic material in most organisms, in some viruses, RNA is the genetic material. According to studies, RNA was the first genetic material. But, since RNA is unstable, DNA evolved from RNA with chemical modifications, and it is more stable and carry more genetic information.
3 cze 2020 · Three key experiments helped resolve the question of whether DNA or protein served as the genetic material. Griffith's transformation experiment showed that heat-killed bacteria could transform live bacteria, indicating a heritable factor.
The discovery of the DNA double helix structure by Watson and Crick in 1953 provided the mechanism for how DNA can store and replicate genetic information. This document discusses the early discoveries and experiments that established DNA as the genetic material.
The document discusses the search for the genetic material, including key experiments by Griffith, Avery, Hershey and Chase, and others that demonstrated DNA as the genetic material. It also describes the composition and structure of DNA, including nucleotides, Watson and Crick's double helix model, and different forms of DNA and RNA.
DNA uses four bases in its structure: adenine (A), cytosine (C), guanine (G), and thymine (T). The order of the bases in a DNA molecule—the genetic code—determines the amino acid sequence of a protein.
