Wild-type strains of e. coli have a trna with a 5′-gua-3′ anticodon that recognizes the uac codon for tyrosine. we can represent this trna as gua-trnatyr. suppose you isolated a strain of e. coli in which a mutation changed the anticodon in this trna to 5′-cua-3′ (creating cua-trnatyr). answer the following questions about translation elongation in each strain. for each answer, type in "yes" or "no".will the wildtype trna recognize a normal uac codon in the a site? will the mutant trna recognize a normal uac codon in the a site? will the wildtype trna recognize a stop codon in the a site? will the mutant trna recognize a stop codon in the a site? will peptide bond formation occur with the wildtype trna bound in the a site? will peptide bond formation occur with the mutant trna bound in the a site? will the normal, wildtype protein be produced in the wildtype strain? will the normal, wildtype protein be produced in the mutant strain?

Which is an advantage of having memory cells when a pathogen is encountered for a second time. a) the memory cells are what proliferate into clones of cells in response to the binding of an antigen. b) memory cells are vital to the primary immune response in that they immediately recognize pathogens even at the first encounter. c) memory cells are essentially effector cells that are short lived and attack antigens even without having a receptor specific to that antigen. d) it ensures that more lymphocytes with a receptor specific to a particular antigen will be present than in a host that had never encountered that pathogen.
