Final answer:
The true statement about translation is option (b): it takes place in the cytoplasm of a cell, where ribosomes synthesize proteins.
Step-by-step explanation:
Among the choices given, the true statement about translation is that it takes place in the cytoplasm of a cell. Translation is the process by which ribosomes synthesize proteins using the genetic information carried by messenger RNA (mRNA). Once transcription has occurred in the nucleus, resulting in the creation of mRNA, this mRNA is transported to the cytoplasm. Here, in the cytoplasm, the ribosomes read the sequence of codons on the mRNA to assemble amino acids in the correct sequence to form a protein. Therefore, option (b) 'It takes place in the cytoplasm of a cell' is correct.
