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

1. The small subunit of ribosome encounters mRNA
2. The larger subunit of ribosome encounters mRNA
3. Both the subunits join together to bind with mRNA

1. Genetic mapping
2. DNA fingerprinting
3. Both genetic mapping and DNA fingerprinting
4. Translation
