Academic session 2026-27, Chapter 9 in the current curriculum.
Welcome to the NCERT Solutions for Class 12 Biology - Chapter Biotechnology Principles and Process. This page offers a step-by-step solution to the specific question from Exercise 1, Question 4: What would be the molar concentration of human DNA in a human cell? Consult your teacher.. With detailed answers and explanations for each chapter, students can strengthen their understanding and prepare confidently for exams. Ideal for CBSE and other board students, this resource will simplify your study experience.
The molar concentration of human DNA in a human diploid cell is as follows:
⇒ Total number of chromosomes × 6.023 × 1023
⇒ 46 × 6.023 × 1023
⇒ 2.77 ×1018 Moles
Hence, the molar concentration of DNA in each diploid cell in humans is 2.77 × 10 23 moles.
NCERT questions are designed to test your understanding of the concepts and theories discussed in the chapter. Here are some tips to help you answer NCERT questions effectively:

Calculation mistakes
How can we say every chromosome's weight is same moreover multiplication is not correct
Not understandable
The answer is not explained Molar concentration is molarity how can calculate the molarity without knowing the volume of cell?
How this possible actual ans is that 277.058NA OR 2.77058NA(Avogadro's)
2.77058Ãâ10^20
6.023 * 10^23 is Avogadro Number
Fair enough But we were supposed to find molar concentration and not no of moles.. we need to divide the number of moles by the volume of a typical cell
Wrong answer/ fake site
From where we took the value 6.023
