Key features of the **genetic code** include all of the following EXCEPT:
ATriplet, non-overlapping, comma-less
BDegenerate (one amino acid → multiple codons)
CLargely universal across organisms
DRead in 3'→5' direction
Answer & Solution
Correct answer: D. Read in 3'→5' direction
Codons are read 5'→3' (the same direction as mRNA synthesis). The other three statements are correct properties of the standard code. (Mitochondrial codes are minor exceptions to universality.)
