Molecular Biology

Molecular biology is the branch of biology that focuses on the study of the structure and function of biological macromolecules at the molecular level. It encompasses the study of DNA, RNA, proteins, and their interactions within cells.

Key Concepts in Molecular Biology

1. DNA Structure and Function: Understand the double helix structure of DNA, the role of DNA in encoding genetic information, and the processes of DNA replication, transcription, and translation.
2. RNA and Protein Synthesis: Explore the different types of RNA (messenger RNA, transfer RNA, ribosomal RNA) and the process of protein synthesis through transcription and translation.
3. Genetic Mutations: Learn about different types of genetic mutations, their effects on protein synthesis, and their implications in inherited genetic disorders.
4. Gene Regulation: Examine the mechanisms by which gene expression is regulated, including transcriptional and post-transcriptional control of gene activity.
5. Recombinant DNA Technology: Explore the techniques and applications of genetic engineering, including gene cloning, PCR (polymerase chain reaction), and gene editing using CRISPR-Cas9.
6. Biotechnological Applications: Understand how molecular biology techniques are used in fields such as medicine, agriculture, and environmental science.
