Question

Which one of the following is linked in long chains to form proteins?

• A. Sugars
• B. Amino acids
• C. Nucleosides
• D. Nucleotides

Answer 1

The correct option is B

Amino acids

The correct option is (B):

Explanation of the correct option:

1. Proteins are the structural and functional organic compound of living organisms.
2. Proteins are made up of amino acids.
3. Amino acids are short-chain molecules, with central animated and carboxylated carbon atoms.
4. Peptide bonds connect multiple amino acids within a protein to form a long chain.

Explanation of the incorrect option:

Option A:

Sugars are linked in long chains to form monosaccharides and polysaccharides.

Option C:

The structural subunit of nucleic acids such as DNA and RNA is nucleosides.

Option D:

Nucleotides are the fundamental building blocks of nucleic acids.

Final answer: Amino acids are linked in long chains to form proteins.
