What does “Genetic code” actually mean in Molecular Basis of Inheritance, and why does it matter for NEET?

a triplet, degenerate, non-overlapping and near-universal code with AUG as start and three stop codons.

In simple words: a triplet, degenerate, non-overlapping and near-universal code with AUG as start and three stop codons. Getting Genetic code clear matters because NEET questions on Molecular Basis of Inheritance usually test this idea directly, not just a formula you memorised.

Key point

Genetic code

Common mistake

thinking one codon can code for several amino acids.

Memory tip

64 codons for 20 amino acids -> many codons per amino acid, never the reverse.
