WebFor example, when A and C were mixed with polynucleotide phosphorylase, the resulting RNA molecules contained eight different triplet codons: AAA, AAC, ACC, ACA, CAA, CCA, … WebThe copy from DNA to RNA is simple: following the complementary base pairing rule. In DNA, there are four nitrogenous base options: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). Each base can only bond with one other, A with T and C with G. This is called the DNA complementary base pairing rule.

WebBecause the only triplet in poly-U mRNA is UUU, Nirenberg concluded that UUU might code for phenylalanine. Using the same approach, he was able to show that poly-C mRNA was translated into polypeptides made exclusively of the amino acid proline, suggesting that the triplet CCC might code for proline. WebIn molecular biology, a reading frame is a way of dividing the sequence of nucleotides in a nucleic acid ( DNA or RNA) molecule into a set of consecutive, non-overlapping triplets. Where these triplets equate to amino acids or stop signals during translation, they …
