Briefly explain translation of mRNA and one common misconception about it.

## Translation of mRNA **Translation** is the process where ribosomes read mRNA sequences and synthesize proteins. It occurs in three stages: 1. **Initiation**: A ribosome binds to the mRNA at the start codon (AUG) 2. **Elongation**: tRNA molecules bring amino acids matching each mRNA codon (3-nucleotide sequence), and the ribosome links amino acids together in a growing chain 3. **Termination**: The ribosome reaches a stop codon and releases the completed protein ## Common Misconception **Misconception**: "One gene makes one protein" or "translation produces an immediately functional protein." **Reality**: The initial translation product is often just the beginning. Many proteins require **post-translational modifications** (folding, cutting, adding chemical groups) to become functional. Additionally, alternative splicing of mRNA means one gene can produce multiple different protein variants, and some genes code for functional RNA molecules rather than proteins at all.
