The first transferase identifications were about 1930. These enzymes include beta-galactosidase, protease, and corrosive/base phosphatase. Previously, it was assumed that at least two catalysts were responsible for accomplishing such actions in the human body. The device for dopamine depletion won the Physiology or Medicine Nobel Prize in 1970. This tool helped research enzyme transferase. Dorothy […]

Recombinant DNA technology is the technique of combining distinct genetic materials (DNA) and introducing them into host organisms from two different species or sources to create new genetic combinations.  Medicine, science, industry, and agriculture all benefit from these new combinations.  The task of inserting a gene into the host genome is not simple.  The appropriate

Introduction “Tissue culture is a technique for growing cells and tissues in an artificial medium that is distinct from the organism in which they are being grown.” It is a technique in which pieces of plants are cultured and grown in a laboratory environment, which is known as tissue culture. Organs are frequently utilised for

Separating substances can be done in a variety of ways, including handpicking, threshing, winnowing, sieving, and magnetic separation. The crop must be harvested once it has matured or ripened. To collect grains, there are three important actions to take. The first step is to cut the crop. The second step is to separate the grain

Cotton is a naturally extracted plant fibre from the cotton plant. Cotton is a soft, fluffy staple fibre widely used to produce shirts, sarees, trousers, socks, towels, earbuds, blankets, medical purposes, and other medical or cosmetic products. The spinning of cotton yarn is a process used to obtain cotton from the cotton plant. Cotton can

Bacteria, singular bacterium, any of a group of microscopic single-celled organisms found in vast numbers in almost every environment on Earth, from deep-sea vents to deep beneath the Earth’s surface to human digestive tracts. Bacteria lack a membrane-bound nucleus and other internal structures, so they are classified as unicellular life-forms known as prokaryotes. Prokaryotes are

Biotechnology is the buzzword of the 21st century. It is the integration of biology and technology. It exploits biological components for large-scale production by manipulating their genetic composition. It is an extensive field that deals with producing substances that aid in uplifting sustainable development. It harnesses all the molecular and cellular processes to create technologies

Fiber is a piece of material that is long, thin, and flexible, like a length of thread. Plant fibers are the basis of fabric such as cotton, silk, and wool fibers that come from animals. In the 20th century, many artificial fibers were invented like nylon and polyester. They are very important in the structure

Synthetic fibres are obtained through the use of chemicals or petrochemicals, and they are manufactured from raw materials such as oil. Several types of fibres are produced from these materials through the process of polymerisation, which results in a long, linear fibre with a variety of chemical components. Even though synthetic fibres are used in

The Ringworm of the body (tinea corporis) that is a fungal infection that causes a rash. It usually appears as an itchy, circular rash with clearer skin in the centre. Ringworm gets its name from the way it looks. There is no worm involved. Athlete’s foot (tinea pedis), jock itch (tinea cruris), and ringworm of
