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 |
