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
What is Trichuris trichiura? Trichuris trichiura, commonly known as the whipworm, is a parasitic roundworm that infects the human intestines. Trichuris trichiura is widespread parasite, affecting millions of people worldwide, particularly in areas with poor sanitation and hygiene. Understanding the life cycle, morphology, pathogenesis, transmission, diseases, diagnosis, and treatment of this parasite is crucial for
The human genome, a complex tapestry of DNA containing the blueprints for life, is not as static as it might seem. Embedded within its intricate structure are mobile elements, known as transposable elements (TEs) or “jumping genes,” capable of moving around the genome. These enigmatic sequences, though once considered “junk DNA,” are now recognized as
Enterobius vermicularis Enterobius vermicularis, commonly known as the pinworm or threadworm, is a parasitic roundworm that infects the human gastrointestinal tract. While often viewed as a nuisance, pinworm infections can cause discomfort and, in rare cases, more serious complications. This guide will delve into the fascinating world of this tiny parasite, exploring its morphology, life
