This section focuses on numerical, quantitative, and data-based problems related to the structure of DNA and RNA. It is designed for Class 11–12 students, NEET aspirants, and undergraduate learners to strengthen their ability to apply molecular structure concepts using calculations and logical reasoning.

In this section, you will practice:

• Numerical problems based on nucleotide composition and base pairing

• Calculations involving percentage of bases using Chargaff’s rules

• Determination of hydrogen bonds and base pair numbers

• Problems related to DNA length, number of base pairs, and turns of helix

• Data-based questions on RNA length and codon calculations

• Interpretation of tables and graphs related to nucleic acid structure

• NCERT-aligned numerical questions and exam-oriented practice sets

The content is structured to improve step-by-step calculation skills, enhance data interpretation, and help students confidently handle numerical and logic-based questions in school examinations, NEET, and undergraduate assessments.

Develop speed, accuracy, and confidence in solving numerical applications related to the structure of DNA and RNA through systematic practice.
