Concept
X-ray crystallography is a powerful technique used to determine the atomic and molecular structure of a crystal by measuring the angles and intensities of X-ray beams diffracted by the crystal lattice. This method has been pivotal in understanding the structures of complex molecules, including proteins and DNA, enabling advancements in fields like chemistry, biology, and materials science.
Concept
Cryo-electron microscopy (cryo-EM) is a powerful imaging technique that allows scientists to visualize the structures of biomolecules at near-atomic resolution without the need for crystallization. It involves rapidly freezing samples to preserve their natural state, enabling the study of dynamic processes and complex molecular assemblies in unprecedented detail.
Fluorescence in situ hybridization (FISH) is a powerful molecular cytogenetic technique used to identify and localize the presence or absence of specific DNA sequences on chromosomes. It employs fluorescent probes that bind to only those parts of the chromosome with a high degree of sequence complementarity, allowing for the visualization of genetic abnormalities and chromosomal rearrangements in various research and clinical applications.
Concept
Gel electrophoresis is a laboratory technique used to separate DNA, RNA, or proteins based on their size and charge by applying an electric field to a gel matrix. This method is essential for genetic analysis, molecular cloning, and forensic science as it allows visualization and quantification of nucleic acids and proteins.
Concept
Molecular modeling is a computational technique used to represent and simulate the structures, dynamics, and interactions of molecules, aiding in the understanding and prediction of molecular behavior. It is crucial in fields such as drug design, materials science, and biochemistry, providing insights that guide experimental research and development.
Concept
Bioinformatics is an interdisciplinary field that combines biology, computer science, and information technology to analyze and interpret biological data, particularly large datasets such as genomic sequences.
