question 33

Essay

One of the NASA rovers returns from its mission with a variety of samples.From one sample the rover has isolated and cultured a unique prokaryotic species that contains many novel amino acids,causing scientists to hypothesize that the genetic code may be different in this organism.Your job is to investigate whether or not the genetic code uses overlapping or non-overlapping codons.Another researcher has data suggesting that rather than codons of three nucleotides,this organism uses groups of four nucleotides.Show how you would verify the presence of overlapping versus non-overlapping codon frames and how you could tell if the codons use three or four nucleotides.Use the following test mRNA sequence in your experiment.
Test mRNA sequence: 5'-AUUGGCCAAUUUACGGUAAUGGCCAAUUUACGGU-3'
