====== Molecular characterization ====== [[Molecular]] characterization refers to the [[analysis]] and [[description]] of the molecular components, [[structure]]s, and properties of a biological system or organism. This can include the identification and analysis of [[DNA]], [[RNA]], [[protein]]s, and other [[macromolecule]]s that make up cells and tissues. Molecular characterization is an important tool in many areas of [[biology]], including [[genetics]], [[genomics]], [[proteomics]], and [[biochemistry]]. It is used to understand the molecular basis of [[disease]], to develop new drugs and therapies, and to study the function and interactions of biomolecules in living systems. Techniques used for molecular characterization include [[DNA sequencing]], [[mass spectrometry]], X-ray crystallography, nuclear magnetic resonance (NMR) spectroscopy, and various imaging techniques such as [[confocal microscopy]] and [[electron microscopy]]. These methods allow scientists to study the structure and function of molecules in great detail, providing insights into how they work and how they can be targeted for therapeutic purposes.
