The process of translation of mRNA to proteins begins as soon as:

1.	The tRNA is activated and the larger subunit of ribosome encounters mRNA
2.	The smaller subunit of ribosome encounters mRNA
3.	The larger subunit of ribosome encounters mRNA
4.	Both the subunits join together to bind with mRNA

How many different proteins does the ribosome consist of?

1.	20	2.	80
3.	60	4.	40
