The sequence of DNA that signals RNA polymerase where to bind and start making RNA is called the promoter Transcription : Transcription The instructions for making proteins are found in the order of the four nitrogenous bases : The instructions for making proteins are found in the order of the four nitrogenous bases This code is read three letters, or nucleotides, at a time Each codon (group of three), specifies a certain amino acid that makes up a protein. In the genetic code, some amino acids are specified by more than one codon Instructions (continued) : Instructions (continued) One codon is a start signal for translation. Three codons signal the end of translation Compare/contrast DNA codons vs. RNA codons : Compare/contrast DNA codons vs. RNA codons DNA uses Thymine RNA uses Uracil as the “anti-codon” DNA codon chart : DNA codon chart RNA codons : RNA codons RNA and Protein Synthesis (Extras) : RNA and Protein Synthesis (Extras) RNA to Protein Synthesis demo DNA to RNA and Protein Synthesis Have fun taking Math and Science AIMS You do not have the permission to view this presentation.
