Molecular Basis of Inheritance Class 12 Notes
Chapter 6 Molecular Basis of Inheritance
The sixth chapter of NCERT notes for Biology is "The Molecular Basis of Inheritance in Genetics". Following the NCERT notes for Biology can be very beneficial for students. This allows students to review an entire chapter in a short amount of time. It also helps clarify all concepts related to this chapter.
CBSE Class 12 Biology Chapter 6 is entirely based on the molecular basis of genetics heredity. Students already have an understanding of genetics because they have completed each chapter in the previous lesson. However, this is a new concept and may be difficult for many students to understand. This allows students to start practicing questions on Vidyakul. Learners can browse practical questions and gain detailed concepts quickly.

Points to Remember
Below we have provided some of the important points for Class 12 Biology Chapter 6. Therefore, students can refer to it.
The long polymers of nucleotides are known as nucleic acid.
While DNA stores genetic information, RNA mostly helps in the transfer and expression of information.
RNA evolved first and from it, the DNA was extracted.
The genes split in the case of eukaryotes.
DNA Fingerprinting is a technique to find out variations in individuals of a population at the DNA level.
Topics and Sub-topics
The NCERT notes for Class 12 Biology Chapter 6 deal with various important subtopics such as DNA, RNA, replication, transcription, and more. Thus, practicing the questions from each of these subtopics from Vidyakul will help the students stay ahead of their peers. Therefore, by referring to these materials, they will soon be able to ace the learning in no time.
Frequently Asked Questions
What are the uses of ‘Polynucleotide’?
Polynucleotides are used in biochemical experiments such as polymerase chain reaction (PCR) or DNA sequencing.
What is a ‘DNA Helix’?
A double helix is the description of the structure of a DNA molecule. A DNA molecule consists of two strands that wind around each other like a twisted ladder.
What is ‘Gene expression regulation?
Regulation of gene expression, or gene regulation, includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products (protein or RNA).
