Ribozymes: Enzymes Made of Nucleic Acids — NEET Biology
✅ Asked in NEET 2024Almost all enzymes are proteins. There are some nucleic acids that behave like enzymes. These are called ribozymes. One can depict an enzyme by a line diagram. An enzyme like any protein has a primary structure, i.e., amino acid sequence of the protein. An enzyme like any protein has the secondary and the tertiary structure. When you look at a tertiary structure
NTA tests whether students know that enzymes aren't always proteins—some nucleic acids like RNA also function as enzymes (ribozymes). Students commonly assume ALL enzymes are proteins, missing this important exception. Ribozymes catalyze reactions like peptide bond formation in ribosomes and self-splicing in some RNA molecules. Remember: ribozymes have the same enzyme properties (specificity, catalytic activity, unchanged after reaction) but are made of RNA/DNA, not protein. This concept appears repeatedly because it challenges the protein-centric view and tests deeper understanding of enzyme nature beyond typical textbook definitions.
