Cell Junctions
Cell junctions Cell junctions are cellular structures, made up of multiprotein complexes. Cell junctions play a crucial role in maintaining the structural integrity and functioning coordination of tissue in multicellular organisms. In humans cell junction serve as a building block of a biological connectivity, facilitating communication and cooperation between neighbouring cells. Cell junctions also helps…

Biosensors
Biosensors Biosensor is a device, probe or electrode consisting of an immobilized enzyme (biocatalyst). It is an analytical device which converts a biological response into an electrical signal. Professor Leland C. Clark is the father of biosensor. He published first example of enzyme electrochemical biosensor by entrapping glucose oxidase in dialysis membrane over a Clark-type…

Cell Division: Mitosis and Meiosis
Cell division Cell division is the fundamental biological process essential for growth, development and maintenance of living organisms. Cell division ensures the accurate distribution of genetic material from parent to daughter cells. During the process of cell division, cells rapidly replicate and divide, playing important role in maintaining the stability and functionality of tissues and…

Preparation and standardization of various molar and normal solutions
Preparation and standardization of various molar and normal solutions The process of determining the exact concentration (molarity) of a solution is known as standardization. Titration is a type of analytical procedure that is frequently used in standardization. A titration involves reacting an exact volume of one substance with a known amount of another substance. 1.Oxalic…
