OF trasc PDF Teas fill All the triplets shift by one base in a deletion mutation, which changes all the codons that follow. Consider the following segment of mRNA produced by the normal order of DNA nucleotides and the corresponding amino acid chain: PDF dave UNOFFIC Ing TRANSCR Mostly cloudy mRNA segment: ACA UCA CGG GUA Amino acid chain: Thr-Ser-Arg-Val If a deletion mutation removes the A at the beginning of that mRNA segment, what will be the new triplet/codon grouping and the new amino acid chain? O CAUCA CGG GUA; Ser-Arg-Val O CAU CAC GGG UA; Thr-Ser-Arg-Val O CAUCA CGG GUA; Thr-Ser-Arg-Val O CAU CAC GGG UA; His-His-Gly O ACA UCA CGG GUA; Ser-Arg-Val O Search PC a huniz recor PD maste omiss C

In each problem the DNA Triplet code is given.  Determine the mRNA codon using base pairing and write the mRNA CODON into the blank. Using the mRNA CODON you identify in each problem and using the amino acid chart on the next page, identify the corresponding 3-letter amino acid (abbreviation) to place in each amino acid blank.  5. GGT (DNA TRIPLET) = _______ (mRNA CODON) = _________ AMINO ACID6. ACA (DNA TRIPLET) = _______(mRNA CODON) = _________ AMINO ACID7. GGG (DNA TRIPLET) = _______ (mRNA CODON) = _________ AMINO ACID8. TCC (DNA TRIPLET) = _______(mRNA CODON) = _________ AMINO ACID 9. CAA (DNA TRIPLET) = _______ (mRNA CODON) = _________ AMINO ACID10. GCC (DNA TRIPLET) = _______ (mRNA CODON) = _________ AMINO ACID11. TAA (DNA TRIPLET) = _______ (mRNA CODON) = _________ AMINO ACID
