the genetic code is a triplet code where 61 out of 64 codons represent 20 amino acids . Because there are significantly more codons than there are amino acids, most amino acids are specified by more than one codon; this characteristic is formally known as the degeneracy of the genetic code . This is a fundamental concept in molecular biology, and mastering such details is critical because NCERT textbooks serve as the definitive primary source for approximately 95% of NEET Biology questions .
