We can define enzymes as biocatalysts. It is important in biological processes like digestion, metabolism, and the synthesis of cellular components. If enzymes stop their functions, then the body can not generate enough proteins, which is important for survival. The examples of enzymes are lactase and amylase.

You must use the NCERT for the CBSE Class 12 board exams. The NCERT textbook is enough for understanding the Biomolecules. All concepts, definitions, and reactions asked in the exams are directly covered in the textbook. We have provided NCERT Solutions for Class 12 Chemistry, Biomolecules, as well as for better practice.
However, for competitive exams like NEET and JEE, while NCERT remains an important resource, students should also solve additional questions from reference books like MTG NCERT at Your Fingertips, NCERT Exemplar, or practice modules by coaching institutes. These help build speed, accuracy, and deeper conceptual clarity

DNA and RNA both are the types of nucleic acids.
DNA (Deoxyribonucleic acid) store the genetic information.
RNA (Ribonucleic acid) helps in protein synthesis. It carry and translates the genetic codes.

We know that nucleic acids are biomolecules which is responsible for carrying the genetic information in living organisms. Nucleic acids have various properties, including physical, chemical and biological properties.
Physical Properties
Nucleic acids are macromolecular in nature because they have a high molecular weight. They are water-soluble but insoluble in alcohol. Also, nucleic acids can absorb ultraviolet light at 260 nm because they have nitrogenous bases.
Chemical Properties
- Acidic in nature
- Hydrolysis
- Base pairing
- Negative charging
Biological Properties
- Stores and transfers genetic information
- The genetic code of every organism i

Nucleic acids are biomolecules which is made of nucleotides. They store and transmit the genetic information. Nucleic acids are of two types: DNA (Deoxyribonucleic acid) and RNA (Ribonucleic acid). The following are the functions of nucleic acids.
1. They store and transfer the genetic information.
2. Nucleic acids help in protein synthesis

Number of mol of A reacted = 1*10? = 10?
Number of molecule of A = 10? * 6 *10²³
Quantum efficiency = (6 *10¹? ) / (1.2 *10¹? ) = 0.50
