The enzyme secreted by the stomach that digests milk protein in infants is: MCQ with Answer and Explanation

Explanation:
Translation is the synthesis of a polypeptide chain at the ribosome, where the genetic code in mRNA is read by tRNA anticodons to assemble amino acids in the correct order. Transcription produces mRNA from DNA, replication duplicates DNA, transduction is gene transfer by viruses. Translation involves initiation, elongation, and termination factors.

Explanation:
Insulin is a peptide hormone produced by the beta cells of the Islets of Langerhans in the pancreas. It is initially synthesized as a single, inactive polypeptide precursor called proinsulin. During processing, a connecting peptide (C-peptide) is removed, leaving two polypeptide chains: the A chain (21 amino acids) and the B chain (30 amino acids). These two chains are held together by two interchain disulfide bridges (covalent bonds between sulfur atoms of cysteine residues), and there is also one intrachain disulfide bridge within the A chain.

Explanation:
