Which statement describes the correct order of events in prokaryotic translation initiation?

#Unit 3. Fundamental Processes

  1. IF1 and IF2 bind the 50S subunit, IF3-fMet-tRNA + mRNA bind the 50S subunit and IF2 leaves to form a 50S initiation complex, the 30S subunit binds and IF1 and IF3 leave to form the 70S initiation complex.

  2. IF1 and IF2 bind the 30S subunit, IF3-fMet-tRNA + mRNA bind the 30S subunit and IF2 leaves to form a 30S initiation complex, the 50S subunit binds and IF1 and IF3 leave to form the 70S initiation complex.

  3. IF1 and IF3 bind the 30S subunit, IF2-fMet-tRNA + mRNA bind the 30S subunit and IF3 leaves to form a 30S initiation complex, the 50S subunit binds and IF1 and IF2 leave to form the 70S initiation complex.

  4. IF1 and IF3 bind the 30S subunit, IF2-fMet-tRNA + mRNA bind the 30S subunit and IF3 leaves to form a 30S initiation complex, the 50S subunit binds and IF1 and IF2 leave to form the 70S initiation complex.
