Question:
When a ribosome first attaches to an mRNA molecule, one tRNA binds to the ribosome at the start codon at the?
A) A site.
B) P site.
C) E site.
General Characteristics of the Genetic Code:
- The genetic code is universal. The same amino acid is represented by the same three-base codon in almost all living organisms.
- Codons are represented by three consecutive bases in the transcript.
- The genetic code is degenerate, meaning that one amino acid may be coded by more than one codon.
- The genetic code is precise. Each codon specifies only one amino acid or stop codon.
- Polypeptide chain initiation is coded by the AUG codon.
- Polypeptide chain termination is coded by the UAA, UAG, and UGA codons.
