Biology

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.

Transpiration in plants: Types, Mechanism, Affecting factors and Significance

Biology /

Transpiration in plants is the process by which plants lose water in the form of water vapor from their aerial parts, primarily through the stomata of leaves. This process is essential for plant physiology, as it drives water movement from roots to leaves and helps regulate temperature. Water is lost by transpiration to the tune […]

Transposable elements characteristics and mechanisms of transposition

Transposable elements: characteristics and mechanisms of transposition

Biology /

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: principle, requirements, procedure, result interpretation and limitations

Biology /

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

CAMP test: Principle, Requirements, Procedure and Result interpretation

Biology /

CAMP test The CAMP (Christie, Atkins, Munch-Petersen) test is a microbiological procedure used to differentiate between two closely related bacterial species: Streptococcus agalactiae (Group B Streptococcus) and Streptococcus dysgalactiae. Both species are commonly found in the human gut, and S. agalactiae can be a significant pathogen, particularly for newborns and pregnant women. Understanding the Principle The CAMP test hinges on

Mumps virus: mode of transmission, pathogenesis, clinical disease and immunization

Biology /

Mumps Virus Mumps, also known as epidemic parotitis, is a contagious viral disease caused by the mumps virus, a member of the paramyxovirus family. Characterized by swelling of the salivary glands, particularly the parotid glands, mumps can cause a variety of complications, including meningitis, encephalitis, and hearing loss. Understanding its transmission, pathogenesis, clinical features, and

Cytomegalovirus (CMV)-Replication, Transmission, Pathogenesis, Diseases, diagnosis and treatment

Biology /

What is Cytomegalovirus? Cytomegalovirus (CMV), a ubiquitous human herpesvirus, belongs to the Betaherpesvirinae subfamily. Its name, derived from the characteristic “cytomegaly” (enlargement of cells) observed in infected tissues, hints at its complex and often insidious nature. CMV infection is widespread, with estimates suggesting over 60% of adults globally harboring the virus. While typically asymptomatic in healthy individuals,
