Some of the
main topics for Biology chapter Molecular Basis of Inheritance (Class
12) along with their details are:
1. DNA structure and replication:
This topic provides an understanding of the structure of DNA, including the
double helix model, nucleotides, and base pairing. It also covers the process
of DNA replication, including the enzymes involved and the semi-conservative
nature of DNA replication.
2. Transcription: This section
explains the process of transcription, including the role of RNA polymerase,
the different types of RNA molecules formed, and the process of mRNA
processing.
3. Genetic code and translation:
This topic covers the genetic code, including the codon sequence and the role
of tRNA molecules, ribosomes, and translation factors in the process of
translation.
4. Regulation of gene expression:
This section explains the different mechanisms for gene regulation, including
transcriptional, post-transcriptional, translational, and post-translational
regulation.
5. DNA damage, repair, and
recombination: This topic covers DNA damage, including the different types of
damage and the mechanisms of DNA repair, including base excision repair,
nucleotide excision repair, and double-strand break repair.
6. RNA interference: This section
covers the process of RNA interference, including the role of small interfering
RNA (siRNA) and microRNA (miRNA) in gene regulation.
7. Human genome project: This topic
provides an overview of the Human Genome Project, including the objectives,
techniques used, and the importance of the project in understanding the human
genome.
8. DNA fingerprinting and its
applications: This section explains the process of DNA fingerprinting,
including the different techniques used, and the various applications of DNA
fingerprinting in forensic investigation, paternity testing, and population
genetics.
Overall, these topics provide an
in-depth understanding of the molecular basis of genetic inheritance and the
mechanisms underlying the expression and regulation of genes. The chapter also
covers the applications of this knowledge in fields such as medicine,
biotechnology, and forensic science.
