Molecular Biology

Molecular biology is a branch of biology that focuses on the study of the structure and function of biological macromolecules at the molecular level. It involves the study of DNA, RNA, proteins, and other biomolecules to understand the processes that occur within living organisms.

Key Concepts in Molecular Biology

1. DNA Structure and Function: DNA is the genetic material that carries hereditary information in living organisms. It is composed of nucleotides and forms a double helix structure. The function of DNA is to store and transmit genetic information.
2. RNA and Protein Synthesis: RNA is involved in the synthesis of proteins through a process called transcription and translation. These processes take place in the cell's nucleus and cytoplasm, respectively.
3. Genetic Mutations: Mutations in DNA can lead to changes in the genetic code, which can affect the structure and function of proteins, and ultimately impact the phenotype of an organism.
4. Gene Expression: Gene expression refers to the process by which information from a gene is used to synthesize a functional gene product, such as a protein.
5. Recombinant DNA Technology: This involves the manipulation of DNA to produce new combinations of genetic material, leading to the development of genetically modified organisms and biotechnology applications.
