What are the three stages of translation process?

The translation process is crucial for protein synthesis, occurring in three distinct stages: initiation, elongation, and termination.

During initiation, ribosomal subunits, along with initiation factors and the messenger RNA (mRNA), come together to form a complete ribosome that is ready to start protein synthesis. This stage ensures that the ribosome is properly assembled at the start codon of the mRNA, setting the stage for translating the genetic code into a polypeptide sequence.

In the elongation stage, amino acids are added one by one to the growing polypeptide chain. This involves the ribosome moving along the mRNA, matching each codon with the corresponding transfer RNA (tRNA) that carries an amino acid. The amino acids added to the chain are linked by peptide bonds, which results in the synthesis of a protein that reflects the sequence encoded by the mRNA.

Termination occurs when the ribosome reaches a stop codon on the mRNA. No corresponding tRNA matches these stop codons, which signals the end of translation. Release factors then bind to the ribosome, promoting the disassembly of the translation complex and releasing the newly synthesized protein.

Each stage of translation is vital for accurately interpreting the genetic information carried by the mRNA
