Environment The term “environment” refers to the surroundings or conditions in which living organisms exist. It encompasses all the physical, chemical, and biological factors that influence and interact with living organisms. The environment can be divided into two main components: The environment is an intricate web of interactions and relationships, and it can be further…
Organisms Organisms are living entities that exhibit characteristics of life, such as growth, reproduction, response to stimuli, and the ability to maintain homeostasis. They are the fundamental units of life and can be found in various forms, ranging from microscopic single-celled organisms to complex multicellular organisms. Organisms can be classified into different kingdoms based on…
Ecology Ecology is the scientific study of the interactions between organisms and their environment. It encompasses the relationships between organisms and their physical surroundings, as well as the interactions among different organisms within ecosystems. Ecology examines how organisms adapt to their environment, how they interact with one another, and how they influence and are influenced…
Transgenic animals Transgenic animals are organisms that have had their genetic material modified by the introduction of genes from another species. This genetic modification is typically accomplished by inserting the desired genes into the animal’s DNA using techniques such as genetic engineering or gene editing. Transgenic animals are created for various purposes, including scientific research,…
Gene therapy Gene therapy is a therapeutic technique that aims to treat or prevent diseases by introducing genetic material into a person’s cells. It involves the delivery of functional genes into targeted cells to replace or repair abnormal genes, thereby restoring normal cellular function and treating the underlying cause of a disease. Gene therapy holds…
Agriculture Agriculture is the practice of cultivating crops, raising livestock, and other activities related to the production of food, fiber, and other products used by humans. It is a vital sector that plays a crucial role in feeding the world’s population and supporting economic development. Key aspects of agriculture include: Agriculture is a multidisciplinary field…
Application and biotechnology in health These are just a few examples of the applications of biotechnology in the field of health. Biotechnology continues to advance rapidly, opening new avenues for disease treatment, prevention, and improved healthcare outcomes. The AIIMS (All India Institute of Medical Sciences) entrance examination is one of the most prestigious medical entrance…
Genetic engineering Genetic engineering is a field of biotechnology that involves the manipulation of an organism’s genes or genetic material to achieve specific outcomes. It allows scientists to modify the genetic makeup of organisms, including plants, animals, and microorganisms, by introducing, removing, or altering specific genes. The process of genetic engineering typically involves several key…
