Biology is the branch of science that primarily deals with the structure, function, growth, evolution, and distribution of organisms. It’s a methodological study of life and living things.
Biology is the scientific study of life. It spans multiple levels, from biomolecules and cells to organisms and populations12. All living things share common biological phenomena, such as reproduction, cell division, and the transmission of genetic material.
What is Interferons ? Interferons (IFNs) are proteins produced by the body’s cells in response to viral infections, tumors, and other threats to the immune system. They serve as critical players in the body’s defense mechanisms, helping the immune system fight off infections and diseases. The name “interferon” comes from their ability to “interfere” with […]

Cholesterol Biosynthesis Cholesterol biosynthesis is the process by which the body makes cholesterol, a vital type of fat. This production happens mainly in the liver, where simple molecules are gradually transformed through a series of steps into cholesterol. Cholesterol is an essential molecule in the body. It is a type of lipid (fat) that plays
Protein Proteins are fundamental to life, acting as the building blocks of cells and performing a wide range of functions. Every process in the body, from digestion to muscle movement, involves proteins. To understand their diversity and importance, scientists classify proteins based on their structure, composition, and function. Let’s explore each classification of Protein in

Autoimmune Disease Autoimmune diseases occur when the body’s immune system, which is supposed to protect us from harmful invaders like bacteria and viruses, mistakenly attacks healthy cells in our body. Think of the immune system as a defense force whose main job is to recognize and destroy foreign invaders. But in autoimmune diseases, this defense

Define Virus Replication? Virus replication is the process through which a virus makes copies of itself after infecting a host cell. Viruses are tiny organisms that are much smaller than bacteria, and unlike bacteria, they cannot live or multiply on their own. Viruses need to invade a living host cell to survive and replicate. This
Live and killed vaccines are types of vaccines designed to help your immune system recognize and fight infections. Live vaccines use a weakened form of the virus or bacteria, while killed vaccines use a completely inactivated (dead) version. Live and killed vaccines help your body build protection without causing the disease. What is Live Vaccine?
Brugia malayi Brugia malayi is a parasitic nematode (roundworm) that causes a disease called lymphatic filariasis, also known as elephantiasis. This disease affects millions of people, particularly in tropical and subtropical regions of Asia, including countries like India, Indonesia, and the Philippines. The parasite is transmitted to humans through the bites of infected mosquitoes, especially
What is Enzyme? Enzymes are biological catalysts that speed up chemical reactions in living organisms without being consumed in the process. They are crucial to life because most of the biochemical reactions in our bodies would be too slow without them. Enzymes make reactions happen quickly enough to support life by lowering the amount of

The Giemsa stain is one of the most widely used laboratory techniques in microbiology and histology, specifically for staining blood cells, bone marrow cells, and parasites such as Plasmodium (the causative agent of malaria). Its primary use is to identify the different cellular components in blood smears and tissue samples. This staining technique plays a
What is Hormones? Hormones are vital chemical messengers that play a key role in regulating many of our body’s functions, from growth and metabolism to mood and reproduction. These molecules are produced in glands and tissues and released into the bloodstream, where they travel to various organs and tissues to help maintain homeostasis—the body’s stable
