A phylogenetic tree (also phylogeny or evolutionary tree) is a branching diagram or a tree that illustrates the evolutionary relationships between various biological species or other entities based on similarities and differences in their physical or genetic characteristics. All life on Earth belongs to a singular phylogenetic tree, indicating a shared ancestry. In a rooted … Read more
Ever wondered how scientists unravel the family ties between different species or genes? It often starts with building something called a phylogenetic tree. Think of it like sketching out a massive family tree, but for life itself. These trees are powerful diagrams that map out evolutionary relationships, showing us who shared a common ancestor and when … Read more
What is Diaphragm of a Microscope? History of Diaphragm Definition of Diaphragm of a Microscope The diaphragm of a microscope is a component that controls the amount of light that passes through the specimen being observed. It is typically located between the light source and the stage, and consists of a series of adjustable blades … Read more
UV-Vis Spectroscopy, short for Ultraviolet-Visible Spectroscopy, is an analytical technique widely used in the fields of chemistry, physics, biochemistry, and molecular biology. It’s based on the absorption or transmission of UV and visible light by substances. At its core, UV-Vis Spectroscopy involves shining ultraviolet or visible light through a sample and measuring how much of … Read more
UV Spectroscopy is a scientific method that’s like a detective tool for scientists. It helps them understand what’s happening in a molecule when it interacts with light, specifically ultraviolet light. This type of light is invisible to our eyes but plays a crucial role in the world of molecules. Imagine a molecule as a tiny, … Read more
What is Objective Lens? Purpose of Objective Lenses Objective lenses serve several key purposes in optical instruments, playing a critical role in magnification, image formation, and resolution. The primary purposes of objective lenses include: Specification of Objective Lens The specification of an objective lens encompasses several key parameters that define its performance and suitability for … Read more
A microscope condenser is an integral optical component in the realm of microscopy, designed to focus and direct light onto the specimen being examined. This specialized lens system is strategically positioned beneath the microscope stage, a placement crucial for optimal illumination. The primary function of the condenser is to gather light from the microscope’s light … Read more
What is Ion Exchange Chromatography? Definition of Ion Exchange Chromatography Ion exchange chromatography is a separation technique that separates ions and polar molecules based on their affinity to ion exchangers. It involves the reversible exchange of ions between the target ions in the sample solution and ions attached to an ion exchanger. Working Principle of … Read more
