Answer:

The answer is Letter B. nonuniversal mitochondrial

Explanation:

The human mitochondrial genome encodes only 22 tRNAs. This limited array of tRNAs can read the 64 possible triplet codons through extreme wobble in base pairing at the third codon position and the use of a nonuniversal mitochondrial genetic code.

Answer: The correct answer is : b. mitochondrial nonuniversal

Explanation: Non-universal genetic codes are frequently found in animal mitochondrial decoding systems. To establish the non-universal genetic code, five mitochondrial tRNAs from a squid are isolated and analyzed. One of the characteristics of mitochondrial decoding systems is the variation in the genetic code.
