Question

The genetic information is carried by long-chain molecules of

• A. Enzymes
• B. Proteins
• C. Nucleotides
• D. Peptides

Answer 1

The correct option is C

Nucleotides

The correct option is (C):

Explanation of the correct option:

1. Long-chain molecules of nucleic acid (DNA) made up of nucleotides carry genetic information.
2. Nucleic acids are function as the genetic material of organisms.
3. Nucleic acids, such as RNA and DNA, are composed of monomers known as nucleotides.

Explanation of the incorrect option:

Option A:

1. An enzyme is a biological catalyst that is itself a protein.
2. The rate of chemical reaction in the cell is accelerated by an enzyme.

Option B:

A protein is a naturally occurring, highly complex substance made up of amino acid residues which is linked together by peptide bonds.

Option D:

A small chain of amino acids from the peptides.

Final answer: The genetic information is carried by long-chain molecules of nucleic acid (DNA), which is made up of nucleotides.
