Molecular biology is a field of science that examines the structure, function, and interactions of biological molecules like DNA, RNA, and proteins within a cell, focusing on how these molecules carry out essential life processes and transmit genetic information, essentially exploring the molecular basis of life at its core. [1, 2, 3, 4, 5, 6]
Key points about molecular biology: [1, 3, 7]
• Central Dogma: The fundamental principle that genetic information flows from DNA to RNA (transcription) and then to proteins (translation). [1, 3, 7]
• Focus on Macromolecules: Primarily studies the structure and function of nucleic acids (DNA and RNA) and proteins. [3, 5, 8]
• Cellular Processes: Investigates how these molecules interact within a cell to regulate processes like cell division, development, and response to environmental stimuli. [1, 3, 5]
• Techniques: Utilizes advanced laboratory methods like DNA sequencing, PCR (polymerase chain reaction), gel electrophoresis, and protein purification to study molecules. [3, 4, 9, 10]
Applications of Molecular Biology: [1, 3, 11]
• Genetics research: Understanding genetic diseases, gene expression patterns, and inheritance [1, 3, 11]
• Medical diagnostics: Developing molecular tests for diseases like cancer and infectious diseases [11, 12]
• Drug development: Designing targeted therapies based on molecular mechanisms [11, 12]
• Biotechnology: Genetic engineering, gene therapy, and production of therapeutic proteins [3, 12, 13]
