Diagram a section of DNA being transcribed. Give the various names for the two strands of DNA.
Answer to relevant QuestionsIs it reasonable that codons for the same amino acid have one or two nucleotides in common? Why or why not? Suggest a reason why the proofreading step in protein synthesis takes place at the level of amino acid activation rather than that of codon–anticodon recognition. Would it be possible to calculate the cost of protein synthesis, including the cost of making mRNA and DNA? Why do scientists now believe that AUG is not always the start codon? What is blue/white screening? What is the key feature of a plasmid that is used for it?
