Answer: (C)

Verified step by step guidance

1. Understand the process of translation: Translation is the process by which ribosomes synthesize proteins using mRNA as a template. It involves decoding the mRNA sequence into a polypeptide chain.
2. Identify the key steps in translation: During translation, the ribosome facilitates the binding of transfer RNA (tRNA) to messenger RNA (mRNA), and peptide bonds are formed between amino acids to create a protein.
3. Recognize the role of mRNA in translation: mRNA provides the sequence of codons that determine the order of amino acids in the protein. The ribosome moves along the mRNA to read these codons.
4. Differentiate between transcription and translation: Transcription is the process of synthesizing mRNA from a DNA template, which occurs in the nucleus. Translation, on the other hand, occurs in the cytoplasm and involves the synthesis of proteins from mRNA.
5. Identify the process that does not occur during translation: Since mRNA synthesis is part of transcription, not translation, the synthesis of mRNA does not occur during translation.
