A) there are 3 nonsense codons and 61 sense codons
B) there are 64 different types of tRNA
C) there are 64 amino acids to be coded
D) genetic code has a triplet nature
Correct Answer: D
Solution :
The group ofnucleotides that specifies one amino acid is a code word or codon. A double code is inadequate because it could specify only sixteen amino acids whereas a triplet code (a code of three letters) could specify 64 amino acids. Therefore, it is likely that there may be 64 triplet codes for 20 amino acids.
