You have identified various tRNAs from a variety of hypothetical orgainisms. Given the anticodon of the tRNA, determine if each tRNA individually could conform to the nearly universal genetic code. Assume that the tRNA in question can only be charged with one amino acid and it is the same amino acid everytime. If the tRNA is not intended to be charged with an amino acid, it can never be charged with an amino acid.

Anticodon: 3\' G C U 5\'

Could this tRNA conform to the nearly universal genetic code?

Anticodon: 3\' A U I 5\'

Could this tRNA conform to the nearly universal genetic code?

Solution

Answer.

1). Yes, anticodon, 3\' G C U 5\' of tRNA conform to the nearly universal genetic code.

2). Anticodon, 3\' A U I 5\' of tRNA do not conform to the nearly universal genetic code

Inosine (I), third base in the codon can pair with A, C or U . this base is called Wobble base or fluctuating base.
