Select the statement which best summarizes the initiation of translation.
| The large ribosomal subunit binds to the mRNA first and the small subunit binds last | 
| The small ribosomal subunit binds to the mRNA first and the large subunit binds last | 
| Both subunits of the ribosome bind to the mRNA simultaneously | 
| There is no large ribosomal subunit, only a small subunit | 
Answer - The option (2) is correct.
The small ribosomal subunit bind to mRNA first and the large subunit bind last.
Explanation - Because small subunit consist of specific sequence which complementary to mRNA sequence. These specific sequence help in tightly binding of small subunit and mRNA .
