Molecular biology is a branch of biology that focuses on the study of the structure and function of biological macromolecules, including nucleic acids and proteins, and the molecular mechanisms by which they control the processes of living organisms.
DNA: This is the geneticmaterial that carries the hereditary information in all living organisms. It is composed of two strands that form a double helix structure.
RNA: This molecule plays a crucial role in the synthesis of proteins and is involved in various other cellular processes.
Proteins: These are large, complex molecules that perform a wide variety of functions in the body, including catalyzing metabolic reactions, replicating DNA, responding to stimuli, and transporting molecules from one location to another.
Gene Expression: This refers to the process by which the information encoded in a gene is used to direct the assembly of a protein molecule. It involves transcription of the DNA into RNA and translation of the RNA into a specific sequence of amino acids to form a protein.
Genetic Engineering: This is the manipulation of an organism's geneticmaterial to modify its characteristics. It has applications in fields such as medicine, agriculture, and biotechnology.
