Question

Which of the following criterion cannot be fulfilled by protein?

(a) Formation of polypeptide chains

(b) Generation of its replica

(c) Formation of alpha helix and beta sheets

(d) Non covalent bonds are present between amino acids

The question was asked in semester exam.

My question is taken from Properties of Genetic Material (DNA versus RNA) in division Molecular Basis of Inheritance of Biology – Class 12

Answer 1

Right option is (b) Generation of its replica

For explanation: Proteins form polypeptide chains by the peptide bond formation between amino acids. Their different folding statures results in the formation of non-covalent bonds as well as the different forms of proteins. Despite these capabilities, proteins lack the ability to generate their replica.
