Task: Class Definition Understanding (ontology: Sciences/Biology)

Which of the following definitions best describes 'cytoplasmic translational termination'?

A. The process resulting in the release of a polypeptide chain from the ribosome in a mitochondrion, usually in response to a termination codon (note that mitochondria use variants of the universal genetic code that differ between different taxa).
B. The series of molecular signals in which an intracellular signal is conveyed to trigger the apoptotic death of a neuron. The pathway is induced in response to a stimulus indicating endoplasmic reticulum (ER) stress, and ends when the execution phase of apoptosis is triggered. ER stress usually results from the accumulation of unfolded or misfolded proteins in the ER lumen.
C. Catalysis of the transfer of an alpha-L-fucosyl residue from GDP- beta-L-fucose to the serine hydroxy group of a protein acceptor.
D. The process resulting in the release of a polypeptide chain from the ribosome in the cytoplasm, usually in response to a termination codon.

Answer: The process resulting in the release of a polypeptide chain from the ribosome in the cytoplasm, usually in response to a termination codon.
