उत्तर
| Basis of Difference | Translation | Translocation |
|---|---|---|
| Meaning | Translation is the overall process of decoding mRNA to synthesise a polypeptide. | Translocation is a step in translation in which the ribosome moves along the mRNA by one codon. |
| Scope | Translation includes initiation, elongation and termination of polypeptide synthesis. | Translocation is one event that occurs repeatedly during elongation. |
| Main movement | During translation, tRNAs enter and leave the ribosome as codons are decoded. | During translocation, the ribosome shifts relative to the mRNA and the tRNA carrying the growing chain moves from the A site to the P site. |
| Outcome | Translation produces a polypeptide with an amino-acid sequence specified by mRNA. | Translocation exposes the next codon at the A site so elongation can continue. |
