Genetic Codon features
- Each codon specifies only 1 amino acid.
- Degenerate/ redundant
- Most amino acids are coded by multiple codons.
- Exceptions: methionine and tryptophan encoded by only 1 codon (AUG and UGG, respectively).
- Commaless, nonoverlapping
- Read from a fixed starting point as a continuous sequence of bases.
- Exceptions: some viruses.
- Genetic code is conserved throughout evolution.
- Exception in humans: mitochondria.
Which one statement is true about the genetic code?
- The genetic code table lists tRNA sequences.
B. Every protein starts with a Pro amino acid.
C. Each amino acid is encoded by exactly one codon.
- Only three codons have no matching anticodons.
- The genetic code table lists anticodon sequences.
Which of the following is not a property of gentic Code
A Non overlapping
B Almost Universal
C Four Stop Codons
