AP Biology / Unit 6: Gene Expression and Regulation
6.4 Translation
Notes
Ribosomes read mRNA codons (3 bases) and tRNAs bring matching amino acids using anticodons.
- Starts at AUG (methionine); ends at a stop codon.
- The genetic code is nearly universal and redundant.
Practice
How many bases make a codon?
Triplets.
The anticodon for codon 5′-AUG-3′ is:
Complementary and antiparallel.
A universal genetic code is evidence for:
All life uses the same code.
