how does the eukaryotic ribosomal small subunit recognize the start codon on the mrna?group of answer choicesit undergoes a conformational charge that recruits other proteins when it hydrogens bonds to the correct tri-nucleotide sequence.it binds an met-trna to the first aug codon after the kozak sequence.it wraps the mrna strand to bring initiation enhancer proteins into the vicinity of the start codon.it binds an met-trna to the first aug codon it encounters.it performs an atp hydrolysis within the small subunit once it encounters a met-trna already bound to the aug.
