Protein Synthesis
1. Transcription
- Enzyme binds to DNA + unzips
- RNA polymerase creates mRNA by base pairing with DNA strand
- occurs in nucleus
- go from DNA → mRNA
DNA → A-T DNA → TAC CCT *u replaces T in RNA
RNA → A-U mRNA → AUG CCA
DNA+RNA→C-G start codon codon
2. Translation
- mRNA binds to ribosome
- tRNA brings anti-codon
- ribosome moves to next codon
- Amino acids are linked by reptide bonds
- repeats until reaches stop codon, then polypeptide is released
Amino Acid Met Pro
tRNA → UAC CCU
mRNA → AUG GGA
DNA → mRNA → tRNA → Amino Acid → protein codon anticodon
