PURINES AND PYRIMIDINES - University of Utah

WebJan 24, 2024 · In DNA, there are two types of nucleotide bases i.e., Purines (Adenine and Guanine) and Pyrimidines (Cytosine, Uracil and Thymine). Apart from inheriting genetic information, DNA also synthesizes protein. You can check NCERT Solutions for Class 12 Biology Chapter 6 for a better understanding of the concept. WebEach nucleotide in DNA contains one of four possible nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T). Adenine and guanine are purines, meaning that their structures contain two fused carbon-nitrogen rings. Cytosine and thymine, in contrast, are pyrimidines and have a single carbon-nitrogen ring.

Web(There are two uncommon amino acids—selenocysteineand pyrrolysine—found in a limited number of proteins and encoded by the stop codons—TGA and TAG respectively.) The mismatch between the number of codons and amino acids allows several codons to code for a single amino acid - such codons normally differ only at the third codon base position. WebMar 27, 2024 · Each nucleic acid contains four of five possible nitrogen-containing base s: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U).
