What is Mendelian Inheritance/Mendel’s Laws of Inheritance? Genetics Terminology of Mendelian inheritance These terms clarify how genes operate, how traits are inherited, and the relationship between genetic information and observable characteristics. Download the Cheat sheet pdf Mendel’s Experiment Gregor Mendel’s experiments between 1856 and 1863 laid the foundation for our understanding of genetic inheritance. Using … Read more
What are Prions? Definition of Prion A prion is an infectious, misfolded protein that causes neurodegenerative diseases by inducing abnormal folding of normal cellular proteins, leading to the accumulation of these misfolded proteins in the brain. Unlike other infectious agents, prions lack nucleic acids and propagate their abnormal structure through direct protein-protein interactions. Characteristics of … Read more
Animal cell are considered to be the fundamental living species belonging to the kingdom Animalia. They are eukaryotic cells which means they possess an actual nucleus as well as organelles, which are special structures which perform various functions. Animal cells don’t have specific organelles for plants, such as cell walls that support the plant cell or the chloroplasts, an organelle that is responsible for photosynthesis.
Acetoacetic acid and acetone react with an alkaline solution of sodium nitroprusside to form a purple-colored complex. This method can detect above 1-5 mg/dl of acetoacetic acid and 10-20 mg/dl of acetone. Beta-hydroxybutyrate is not detected.
Domain: Bacteria Phylum: “Firmicutes” Class: Bacilli Order: Bacillales Family: Bacillaceae Genus: Bacillus Species: B. cereus Definition of Bacillus cereus Bacillus cereus is a gram-positive, rod-shaped bacterium that produces toxins leading to foodborne illnesses. It can cause two main types of gastrointestinal disorders: emetic (vomiting) syndrome and diarrheal syndrome. This bacterium is commonly found in soil … Read more
The fact that they are both cells that are eukaryotic, meaning they have a real nucleus that is enclosed and separate from other organelles through a nuclear membrane is a key element which determines their ways of multiplication. They share the same reproduction process of meiosis and mitosis by using their DNA, which is stored in the cell’s nucleus.
What is Simple Microscope? Definition of Simple Microscope A simple microscope is an optical device consisting of a single convex lens that magnifies objects by enlarging their image through light refraction. Principle of Simple Microscope Working Mechanism of Simple Microscope This ray diagram in below, explains how simple microscopes is working; Magnification of a simple … Read more
What is HPLC (High-performance liquid chromatography)? Principle of HPLC (High-performance liquid chromatography) Instrumentation of HPLC High-Performance Liquid Chromatography (HPLC) is a sophisticated analytical technique that relies on a precise set of instruments to achieve effective separation, detection, and analysis of chemical compounds. The key components of an HPLC system include the mobile phase reservoir, solvent … Read more
