Next, the separated compoundswere converted into mercury salts.
WebThe DNA molecule consists of 4 nitrogen bases, namely adenine (A), thymine (T), cytosine (C) and Guanine (G), which ultimately form the structure of a nucleotide. The A and G are purines, and the C and T are pyrimidines. The two strands of DNA run in opposite directions. These strands are held together by the hydrogen bond that is present ...
Die Chargaff-Regeln wurden von 1952 bis 1968 von Erwin Chargaff aufgestellt. Sie umfassen die Parität (gleiche Anzahl) von Nukleinbasen auf beiden DNA-Strängen zwischen Purinen und Pyrimidinen und die Parität zwischen Adenin und Thymin bzw. Guanin und Cytosin.
