Durng translation, polypeptide/protein synthesis continues until what happens?

A) all tRNA's are empty (uncharged)

B) no further amino acids are needed by the cell

C) the polypeptide is long enough

D) the ribosome encounters a stop codon

E) the ribosome runs off the end of the mRNA

The correct answer is option D.

Explanation:

The process of translation, that is, synthesis of proteins takes place until the occurrence of the termination process. The termination takes place when the ribosome encounters a stop codon. These are UAG, UAA, and UGA. As there are no molecules of tRNA, which can identify these codons, the ribosome determines that the process of protein synthesis is complete. The formed protein then get discharged and the complex of translation move away from each other.
