How to Calculate Protein Synthesis
What is Protein Synthesis?
Protein synthesis converts genetic information (DNA → mRNA → protein). Transcription produces mRNA from DNA; translation converts mRNA codons into amino acid sequences.
Step-by-Step Guide
- 1Transcription: RNA polymerase reads DNA 3→5, synthesises mRNA 5→3
- 2Each codon (3 bases) codes for one amino acid
- 3Protein length ≈ gene coding length / 3 amino acids
Worked Examples
Input
Gene of 900 bp coding sequence
Result
300 amino acid protein
900÷3=300 codons
