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

The Chromosomal Theory of Inheritance is a key idea in genetics that explains how traits are passed down from parents to their offspring through genes carried on chromosomes. Let’s break Chromosomal theory of inheritance down in simple language and use some examples to understand it better. Basics of Genetics To understand this theory, we first
Chromosomes are the structures in our cells that carry our genetic information. Humans usually have 46 chromosomes arranged in 23 pairs. Sometimes, mistakes happen during the division of cells, which leads to changes in the number of chromosomes. These mistakes are known as numerical chromosomal aberrations or chromosomal genomic mutations. They can lead to a

Antisense technology is a fascinating topic of molecular biology that is used to restrict the expression of certain genes. Once we dissect it, it turns out to be really simple even though it sounds complex. If your body were a city, your genes would be the engineers that plan and direct the construction and upkeep
What is Influenza virus? Influenza, commonly known as the flu, is a highly contagious viral infection that primarily affects the respiratory system. It’s responsible for seasonal flu outbreaks every year and, at times, can cause pandemics. Influenza virus is a contagious virus that primarily infects the respiratory system, causing the flu, and is known for
Transposable elements (TEs), also known as “jumping genes,” are DNA sequences that can change their position within a genome. These elements are present in almost all organisms, including plants, animals, and even bacteria. The discovery of transposable elements revolutionized our understanding of genetics, showing that the genome is not a static entity but rather a

Acridine Orange Staining: Simple Explanation Acridine orange staining is a technique used in laboratories to detect and differentiate between DNA and RNA in cells. It is especially useful for identifying certain infections, assessing cell health, and diagnosing conditions like cancer. This method uses a special fluorescent dye called acridine orange, which binds to genetic material
