How does the eukaryotic ribosomal small subunit recognize the start codon on the mRNA?
A) It binds an Met- tRNA to the first AUG codon it encounters.
B) It binds an Met- tRNA to the first AUG codon after the Kozak sequence.
C) It performs an ATP hydrolysis within the small subunit once it encounters a Met- tRNA already bound to the AUG.
D) It undergoes a conformational charge that recruits other proteins when it hydrogens bonds to the correct tri- nucleotide sequence.
E) It wraps the mRNA strand to bring initiation enhancer proteins into the vicinity of the start codon.
