Staphylococcus aureus is a Gram‑positive, facultative anaerobic bacterium, usually found in clusters that resemble grapes and typically 0.5–1µm in diameter. Harbor, as a commensal organism, in the human nasal passages, skin, and mucous membranes of 20–30% of people without causing disease It is an opportunistic pathogen that can cause a wide range of infections—from simple … Read more
Pectin is a complicated polysaccharide that is mostly found in the cell walls of plants, notably fruits. It is a structural heteropolysaccharide made up mostly of units of galacturonic acid. Pectin is a glue that holds plant cells together, making the plant tissue strong and stable. In the culinary sector, it is often used as … Read more
A biosafety level (BSL) refers to a specific set of biocontainment measures designed to isolate hazardous biological agents within a controlled laboratory environment. This document outlines the necessary protective measures required in a laboratory environment to safeguard employees, the ecosystem, and the community from infectious agents. Historical Overview The classification of four levels of biosafety … Read more
What is Southern Blot? What is Western Blot? Southern Blot vs Western Blot Here is a detailed comparison between Southern blotting and Western blotting: Feature Southern Blotting Western Blotting Target Molecule DNA Protein Purpose Detection of specific DNA sequences within a complex DNA sample Detection and analysis of specific proteins in a sample Developed By … Read more
All living organisms are grouped into three major categories under the three-domain system, a modern way to classify life based on genetic and evolutionary relationships. Proposed by microbiologist Carl Woese in the 1990s, this system splits life into Bacteria, Archaea, and Eukarya. Bacteria are the familiar single-celled microbes found everywhere, from soil to our bodies, lacking a cell … Read more
Biodiversity hotspots are regions packed with an extraordinary variety of plant and animal life found nowhere else on Earth—but they’re also in serious trouble. To qualify as a hotspot, an area must have at least 1,500 unique plant species and have already lost over 70% of its original natural habitat due to human activities like … Read more
Funaria is a moss you’ll often find thriving in damp, shady areas like forest floors or along stream banks. Unlike typical plants, it lacks true roots, stems, or leaves, absorbing water and nutrients directly through its surface. If you take a closer look, you’ll spot its vibrant green tufts topped with tiny, capsule-like structures—these hold … Read more
