Question

if the template strand of a gene in your chromosome wereTACAAAGACAAAAATC, what would the sequence of amino acid s in thepoly peptide be? if a tRNA molecule had the anticodon UUC, what amino acidwould it be carrying? what type of a single base mutation will most likely result ina non-function polypeptide? when both extremes in a populations phonotype areselected against an enviroment, this is what type ofselection? WILL RATE 7--thanks so much!!! if the template strand of a gene in your chromosome wereTACAAAGACAAAAATC, what would the sequence of amino acid s in thepoly peptide be? if a tRNA molecule had the anticodon UUC, what amino acidwould it be carrying? what type of a single base mutation will most likely result ina non-function polypeptide? when both extremes in a populations phonotype areselected against an enviroment, this is what type ofselection?

Explanation / Answer

      When the template strandof a gene in a chromosome has a sequence of TACAAAGACAAAAATC; theRNA that       corresponds to this strandis AUGUUUCUGUUUUUAG.       T A C A A A G A C AA A A A T C       A U G U U U C U G U U U UU A G       The sequence of aminoacids for this m-RNA will be       AUG UUU CUG UUU UUAG       Met    Phe   Leu    Phe Leu
      If the t-RNA molecule has theanticodon UUC the codon that corresponds to this sequence isAAG.       This AAG codon correspondsto the amino acid Lysine.
      To start a protein synthesisthe initiating codon is AUG that codes for the amino acidMethionine.       Protein synthesis startsonly at this codon if this codon is not present at the start siteprotein synthesis is not initiated.       So, if a mutation in thefisrst base of AUG, that is if A is replaced by any othernucleotide except G, then that results in       a non-functionpolypeptide.
