Necrosis- Definition, Types, Causes, Mechanism, Symptoms, Treatment
Introduction: Necrosis is defined as irreversible cell damage and eventual cell death caused by pathogenic processes. It is an uncontrolled cell death that causes enlargement of the cell organelles, plasma membrane rupture and ultimately cell lysis, and leakage of intracellular contents into surrounding tissue, resulting in tissue injury. It is the death of cells or

Animal Cell- Definition, Structure, Types, Functions
Introduction: An animal cell is a type of eukaryotic cell that is characteristic of animals. Eukaryotic cells are characterized by the presence of a true nucleus, which contains the cell’s genetic material in the form of DNA. Animal cells also have several other membrane-bound organelles, such as mitochondria, which are responsible for generating energy for

Fragile X syndrome (FXS)- Introduction, Frequency, Causes, Diagnosis, Treatment
Introduction: Fragile X syndrome (FXS) is a genetic disorder that causes a variety of developmental issues such as learning impairments and cognitive impairment. It is caused by a mutation in the FMR1 gene, which is responsible for producing a protein called fragile X mental retardation protein (FMRP). This protein plays a critical role in the

DNA Barcoding- Definition,Types, Procedure, History, Applications
DNA barcoding is a powerful technique revolutionizing biodiversity research and species identification. It involves analyzing short gene sequences, such as the mitochondrial cytochrome c oxidase subunit I (COI), to distinguish and classify organisms. By comparing these DNA barcodes to reference databases, researchers can accurately identify species, even those with morphological similarities or at different life stages.
The process begins with specimen collection, followed by DNA extrac
