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.

7. Anticodon: 3' U G G 5'

Could this tRNA conform to the nearly universal genetic code?

Select one:

Yes

No

8. Anticodon: 3' U A I 5'

Could this tRNA conform to the nearly universal genetic code?

Select one:

Yes

No

Explanation / Answer

Answers:

Question 7: Yes

Explanation: Anticodons are the three-base segments present in transfer RNA (tRNA). A set of rules by which information encoded within genetic material (DNA or mRNA sequences) is translated into proteins is called genetic code. Genetic code consist of A,T,G,C and U nitrogenous bases. The given tRNA with anticodon UGG, can conform to the nearly universal genetic code and it can code for the aminoacid Tryptophan.

Question 8: No

Explanation: The genetic code is universal and its is the common language for almost all organisms to translate nucleotide sequences of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) to amino acid sequences of proteins. The given anticodon UAI on tRNA cannot be considered as universal genetic code, because it has an unusual base "I"along ith U and A.
