Basic concepts of Tissue Culture Basic concepts of plant tissue culture are totipotency, differentiation, dedifferentiation and redifferentiation. Totipotency The property of live plant cells that they have the genetic potential when cultured in nutrient medium to give rise to a complete individual plant. Differentiation The process of biochemical and structural changes by which cells become […]

Applications of Biotechnology • Biotechnology is one of the most important applied interdisciplinary sciences of the 21st century. It is the trusted area that enables us to find the beneficial way of life. • Biotechnology has wide applications in various sectors like agriculture, medicine, environment and commercial industries. • This science has an invaluable outcome […]
Bioprospecting is the process of discovery and commercialization of new products obtained from biological resources. Bioprospecting may involve biopiracy, in which indigenous knowledge of nature, originating with indigenous people, is used by others for profit, without authorization or compensation to the indigenous people themselves. Biopiracy Biopiracy can be defined as the manipulation of intellectual property […]
Algal fuel, also known as algal biofuel, or algal oil is an alternative to liquid fossil fuels, the petroleum products. This is also used as a source of energy-rich oils. Also, algal fuels are an alternative to commonly known biofuel sources obtained from corn and sugarcane. The energy crisis and the world food crisis have […]
Biopharming also known as molecular pharming is the production and use of transgenic plants genetically engineered to produce pharmaceutical substances for use of human beings. This is also called “molecular farming or pharming”. These plants are different from medicinal plants which are naturally available. The use of plant systems as bioreactors is gaining more significance […]
The green fluorescent protein (GFP) is a protein containing 238 amino acid residues of 26.9 kDa that exhibits bright green fluorescence when exposed to blue to ultraviolet range (395 nm). GFP refers to the protein first isolated from the jellyfish Aequorea victoria. GFP is an excellent tool in biology due to its ability to form […]
Polyhydroxybutyrate (PHB) Synthetic polymers are non-degradable and pollute the soil and when burnt add dioxin in the environment which cause cancer. So, efforts were taken to provide an alternative eco-friendly biopolymers. Polyhydroxyalkanoates (PHAs) and polyhydroxybutyrate (PHB) are group of degradable biopolymers which have several medical applications such as drug delivery, scaffold and heart valves. PHAs […]
Golden rice is a variety of Oryza sativa (rice) produced through genetic engineering of biosynthesized beta-carotene, a precursor of Vitamin-A in the edible parts of rice developed by Ingo Potrykus and his group. The aim is to produce a fortified food to be grown and consumed in areas with a shortage of dietary Vitamin-A. Golden […]
Agrobacterium mediated genetic engineering technique was followed to produce Flavr-Savr tomato, i.e., retaining the natural colour and flavor of tomato. Through genetic engineering the ripening process of the tomato is slowed down and thus prevent it from softening and to increase the shelf life. The tomato was made more resistant to rotting by Agrobacterium mediated […]
Sometime in May 1942 Gandhi took it upon himself to steer the Indian National Congress into action. Gandhi’s decision to launch a mass struggle this time, however, met with reservation from C. Rajagopalachari as much as from Nehru. Conditions were ripe for an agitation. Prices of commodities had shot up many-fold and there was shortage […]
Japan Storm South-East Asia T he year 1941 was bad for the allied forces. France, Poland, Belgium, Norway and Holland had fallen to Germany and Great Britain was facing destruction as well. Of far more significance to India was Japan’s march into South-east Asia. This was happening alongside the attack on Pearl Harbour, where Japanese […]
Individual Satyagraha Unlike in the past, where Gandhi’s campaign had assumed a mass character, Gandhi decided on the strategy of individual Satyagraha so that the war against fascism was not hampered. The satyagrahis were handpicked by Gandhi and their demand was restricted to asserting their freedom of speech to preach against participation in the war. […]
Insect resistance – Bt Crops: i. Bt Cotton Bt cotton is a genetically modified organism (GMO) or genetically modified pest resistant plant cotton variety, which produces an insecticide activity to bollworm. Strains of the bacterium Bacillus thuringiensis produce over 200 different Bt toxins, each harmful to different insects. Most Bt toxins are insecticidal to the […]
Trade name ‘Basta’ refers to a non-selective herbicide containing the chemical compound phosphinothricin. Basta herbicide tolerant gene PPT (L-phosphinothricin) was isolated from Medicago sativa plant. It inhibits the enzyme glutamine synthase which is involved in ammonia assimilation. The PPT gene was introduced into tobacco and transgenic tobacco produced was resistant to PPT. Similar enzyme was […]
Weeds are a constant problem in crop fields. Weeds not only compete with crops for sunlight, water, nutrients and space but also acts as a carrier for insects and diseases. If left uncontrolled, weeds can reduce crop yields significantly. Transgenic plants contain a novel DNA introduced into the genome. Glyphosate herbicide produced by Monsanto, USA […]
All characters of organism are the result of expression of different genes which are regions of nuclear DNA. This expression involves transcription and translation. Transcription refers to the copying of genetic information from one strand of the DNA (called sense strand) by RNA. This RNA, as soon as it formed cannot be straight away sent […]
