1. The nontemplate strand of a segment of double- helical DNA contains the sequence: (5')CGCTATAGCGTTTAG (3') (a) What is the MRNA base sequence that can be transcribed from this double helical DNA assuming you already have a ready RNA polymerase present and everything else needed for RNA transcription? Label the sequence ends and list what is required for RNA Pol to work. (b) What amino acid sequence could be coded by the mRNA in (a)'s answer assuming the AUG start codon is just upstream of the mRNA (not shown in the sequence provided)? Use table in Figure 27-7 of the Lehninger 7 th ed "Dictionary of amino acid code words in mRNAs" and write the peptide according to standard convention with abbreviations for the amino acids. (c) If the wrong strand was transcribed and then translated from the section of double stranded DNA shown above, what would the resulting amino acid sequence be? What would the MRNA sequence be? Explain your answer and label all strands. 系: 2222 阳 高的 the twentieth century First letter of codon (5' end) Second letter of codon U A UUU Phe UCU Ser u UUC Phe UCC Ser UAC Tyr UGC Cys UUA Leu UAU Tyr UGU Cys UUG Leu CUU Leu CAU His CGU Arg c| CÚC Leu CUA Leu CUG Leu CCA Pro CCG Pro ACU Thr ACC Thr ACA Thr ACG Thr AUU lle AUC lle AUA lle AUG Met AAG Lys GCU Ala GAU Asp GCC Ala GAC Asp GCA Ala GAA Glu GAG Glu GUU Val GUC Val GUA Val GUG Val GCG Ala
