Which of the following defines the role of eIF2?
A) eIF2 binds Met-tRNAm and delivers it to the 40S ribosomal subunit.
B) eIF2 mediates the formation of the 80S initiation complex.
C) eIF2 binds MET-tRNAi and delivers it to the 40S ribosomal subunit.
D) eIF2 is the cap binding protein.
E) eIF2 binds Met-tRNAi and delivers it to the 60S ribosomal subunit.

Question

Quizplus · Accepted Answer

eIF2 plays a critical role during initiation of protein synthesis, where it binds Met-tRNAi and delivers it to the 40S ribosomal subunit, facilitating initiation of translation. This binding initiates a series of events that ultimately lead to the formation of the 80S initiation complex. Therefore, option C, which states that eIF2 binds MET-tRNAi and delivers it to the 40S ribosomal subunit, is the correct answer.
