The event that happens after the translation of mRNA begins at the start codon is elongation, mediated by elongation factors. The correct option is d.
What is translation?
The translation is the second step of protein synthesis in the cell. Translation occurs after the DNA is transcribed to the mRNA by the process of transcription.
In translation, there are three steps, including initiation, in which the mRNA starts the protein synthesis. Elongation, in which the protein continues to process. And termination, in which stop codons came and stop the process.
So, when the process begins, that is initiation. The nest step will be elongation, which is given in option d. The last step is termination.
Thus, the correct option is d.) elongation mediated by elongation factors.
