The process responsible for decoding mRNA to produce proteins is translation. During translation, the mRNA molecule, which has been synthesized from DNA through transcription, is read by ribosomes in the cytoplasm. The ribosomes facilitate the assembly of amino acids into a polypeptide chain based on the sequence of codons in the mRNA. Each codon corresponds to a specific amino acid, and the transfer RNA (tRNA) plays a critical role in bringing the appropriate amino acids to the ribosome for incorporation into the growing protein chain.

In contrast, transcription is the process of creating the mRNA from a DNA template, which occurs in the nucleus and does not involve decoding for protein production. Glycolysis and fermentation are metabolic processes related to energy production in cells, but they do not directly involve the decoding of mRNA or the synthesis of proteins.
