Final answer:
Translation termination is true to conclude with the dissociation of ribosomal subunits and mRNA; it is initiated by a stop codon which leads to the release of the polypeptide and the ribosomal components separation.
Step-by-step explanation:
The statement that translation termination concludes with the dissociation of the two ribosomal subunits and mRNA from each other is indeed true. Translation termination is a critical process that occurs when the ribosome encounters a stop codon (UAA, UAG, or UGA). At this point, release factors recognize these codons, and a complex series of reactions lead to the finished polypeptide chain being released. Following the release of the new protein, the ribosomal subunits dissociate from the mRNA and from each other, making them available for future translation initiation complexes. Over time, the mRNA itself is degraded, allowing its constituent nucleotides to be recycled and used anew in transcription reactions.
