_____ codon combinations code for amino acids.

Explanation:
Triplet codons specify amino acids, and there are 64 possible codons from four nucleotides. Three of these act as stop signals, ending translation. That leaves 61 codons that code for amino acids. The genetic code is degenerate, so multiple codons can encode the same amino acid, which is why 61 codons map to 20 different amino acids.
