Class 12 Biology Chapter-6: Molecular Basis of Inheritance Notes
In the previous chapter-5 Principles of Inheritance and Variation, you have learnt the inheritance patterns and the genetic basis of such patterns. At the time of Mendel, the nature of those ‘factors’ regulating the pattern of inheritance was not clear. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are the two nucleic acids found in living systems. DNA acts as the genetic material in most organisms. RNA though it also acts as genetic material in some viruses, mostly functions as a messenger. RNA has additional roles as well. It functions as an adapter, structural, and in some cases as a catalytic molecule.

Class 12 Molecular Basis of Inheritance Notes
Students spend a lot of time on the internet to find the downloadable format of Class 12 Biology Chapter-6 Molecular Basis of Inheritance Notes. Here through this PDF, we have tried to bring the Best study material for NEET free of cost. Moreover, students can take the reference of these notes to score great in their Board examination.
At the time of Mendel, The nature of the ‘Factors’ regulating the pattern of inheritance was not clear.
Two types of nucleic acids are found in living systems-
i) Deoxyribonucleic acid (DNA) and
ii) Ribonucleic acid (RNA).
>DNA is the genetic material in most organisms.
>RNA also acts as genetic material, but it also functions as a messenger, as an adapter, structural and catalytic molecule.
The DNA
-It is a long polymer of deoxyribonucleotides.
-The length of DNA is usually defined as the number of nucleotides (or a pair of nucleotides referred to as base pairs)
-This is also the characteristic of an organism.
For example:
1) Bacteriophage ϕ×174 has 5386 nucleotides
2) Bacteriophage Lambda has 48502 base pairs.
3) Escherichia coli has 4.6×106 base pairs.
4) Haploid content of human DNA is 3.3×109 base pairs
