Sheet1 Page 1 - sequence of 3 nucleotides = 1 codon - 1 codon codes for one amino acid - more than enough for the 20 amino acids - 1 to 6 different codons for same amino acid - also have start codon and 3 stop codons - so code for a protein will have x + 2 codons - tables transcribe portion of DNA to protein production site (ribosomes) DNAComp StrandmRNAtRNA G CCG ATcode forUA (GAC is anticodon) CGamino acidGC Steps in Protein Production - called translation - process of extending the being-built protein is called elongation 8. After a codon is read and its amino acid is fitted into the proper sequence, the mRNA moves to bring its codon onto the ribo s 9. After protein is completed, it breaks away - called termination Further INFO on genetic material Terms -- may be intermeshed with exons Steps in Transcription 1.RNA polymerase finds appropriate promoter and opens up just that part of the DNA 2.mRNA is transcribed between promoter and terminator 3.introns are cut out leaving just the functional part of the gene (the extrons)
