Which of the following is not produced when RNA is hydrolyzed?

Amino acid

The correct answer is option 3. Amino acid.

RNA (ribonucleic acid) is composed of repeating units called nucleotides. Each nucleotide includes: a pentose sugar (ribose in RNA), a nitrogenous base (adenine, guanine, cytosine, or uracil) and phosphate group.

When RNA is hydrolyzed, the following occurs:

The hydrolysis process breaks the phosphodiester bonds between nucleotides in the RNA strand, resulting in individual nucleotides. Each nucleotide is then hydrolyzed into its component parts:

Pentose Sugar: Ribose is released as the sugar component.

Nitrogenous Bases: Adenine, guanine, cytosine, and uracil are released as the base components.

Phosphoric Acid: The phosphate group of each nucleotide is hydrolyzed into phosphoric acid.

Amino acids are not produced from RNA hydrolysis. Here  is why:

Amino Acids are the building blocks of proteins, not nucleotides. Proteins are made up of amino acids linked together by peptide bonds. To obtain amino acids, you would need to hydrolyze proteins, not nucleic acids.

Summary

Pentose Sugar: Ribose, a component of RNA, is released.

Nitrogen Bases: Adenine, guanine, cytosine, and uracil are released.

Phosphoric Acid: Phosphate groups are hydrolyzed to form phosphoric acid.

Amino Acids: Produced from the hydrolysis of proteins, not nucleic acids.

So, when RNA is hydrolyzed, amino acids are not produced.
