Question: 1the atgc ratios of e coli and mycobacterium tuberculosis differ...
1)The (A+T)/(G+C) ratios of E. Coli and Mycobacterium tuberculosis differ significantly. In which of the following classes of genes, those that encode (a) tRNAs, (b) rRNAs or ( c) mRNAs would there most likely be a large difference in the (A+T)/(G+C) ratios between these two species? Explain your reasoning.
2) Describe the main differences between bacterial and eukaryotic transcripts.
3)When researchers used a synthetic polynucleotide with the sequence CGU repeated many times (CGUCGUCGUCGU…) in an in vitro translation system, they obtained the following polypeptides: polyarginine, polyvaline and polyserine. Explain why this result indicates that the genetic code consists of trinucleotide codons.
