Question

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' U C I 5'

Could this tRNA conform to the nearly universal genetic code?

Select one:

Yes

No

Answer 1

No,one amino acid is coded by many codons,but anticodon present on t-rna is UCI in which one position is variable which is of inosine and work for the many bases present on the m-rna but one charged t-rna is applicable only for one codon present on m-rna by which they codes for one amino acid and then this t-rna will uncharged and exit from the ribosomal tranlational complex and then next t-rna will reach here to elongate the polypeptide chain.
