Translation Cheat Sheet

Key Definitions

• Translation: The process of synthesizing proteins from mRNA templates. ✅

• mRNA (messenger RNA): Carries genetic information from DNA to the ribosome. ✅

• Ribosome: Cellular machinery that facilitates protein synthesis. ✅

Important Concepts

Stages of Translation

• Initiation: Ribosome assembles around the start codon on mRNA. ✅

• Elongation: tRNA brings amino acids to ribosome; peptide bonds form. ✅

• Termination: Ribosome reaches a stop codon; polypeptide chain is released. ✅

Key Players

• tRNA (transfer RNA): Transfers specific amino acids to the ribosome. ✅

• Amino Acids: Building blocks of proteins; 20 standard types. ✅

Key Formulas

• Amino Acid Sequence: mRNA codons → tRNA anticodons → Amino acids

• Peptide Bond Formation: Amino acid1 + Amino acid2 → Dipeptide + H2O ✅

Common Mistakes to Avoid

Common Mistake: Confusing the roles of mRNA and tRNA during translation.

Memory Tricks

Tip: "AUG" — Amino acids, Universal start codon, Growing polypeptide chain.
