question 14

Essay

One of the NASA land rovers returns from its mission with a variety of samples.From one,a unique bacterial species has been isolated and cultured.Your job is to investigate whether or not the genetic code is overlapping or nonoverlapping.Another researcher has discovered that rather than a codon of three nucleotides,this organism uses groups of four nucleotides.Show how you would verify the presence of overlapping versus nonoverlapping frames when you thought the codon was read in groups of three nucleotides and in groups of four nucleotides.How would your data have been different without the knowledge of codons as groups of four nucleotides?
