Answer:

tRNA.

Explanation:

Two main types of nucleic acid present in the organism are DNA and RNA. DNA is present as genetic material in all the organisms except some viruses. RNA is present as genetic material in some viruses only.

The nucleic acid that has been purified contains uracil and bound to an amino acid. This nucleic acid is tRNA or transfer RNA as RNA contains uracil instead of thymine and only tRNA can bound covelently with amino acid. tRNA contains anticodon specific for mRNA on its structure that forms a specific amino acid.

Thus, the correct answer is option (4).
