Pronucleus is the nucleus of a sperm or an egg cell during the process of fertilization. The sperm cell becomes a pronucleus only after the sperm enters the ovum, but before the fusion of genetic material of the sperm and egg. The technique of pronuclear transfer involves the transfer of pronuclei from one zygote to another. Under… Continue reading Pronuclear Transfer can be used for Prevention of mitochondrial diseases in offspring

Pneumococcal Conjugate Vaccines are effective against pneumonia
Pneumococcal Conjugate Vaccines are effective against pneumonia as well as meningitis and sepsis. Pneumococcal disease refers to any illness caused by pneumococcal bacteria. These bacteria can cause many types of illnesses, including pneumonia, meningitis, blood infections, and Sepsis. Dependence on antibiotics that are not effective against drug-resistant bacteria can be reduced. Pathogen gets lesser time to evolve with vaccination… Continue reading Pneumococcal Conjugate Vaccines are effective against pneumonia
Applications of drones
In aviation and in space, a drone, also called an “unmanned aerial vehicle,” or UAV, refers to an unpiloted aircraft or spacecraft. To reduce weight and increase manoeuvrability, a typical unmanned aircraft is made of light composite material allowing military drones to cruise at extremely high altitudes. UAVs are controlled by remote ground control systems… Continue reading Applications of drones
Plant Vs Animal cells
Both plant and animal cells are eukaryotic i.e. they contain a nucleus and organelles, and are enclosed by a plasma membrane. Protozoa, fungi, plants and animals have Eukaryotic cells. Plant cells are unique among eukaryotic cells for several reasons. For maintenance of structural support, plants have reinforced, relatively thick cell walls that are made mostly of… Continue reading Plant Vs Animal cells
Benzene Pollution
Benzene Pollution is a colourless or light-yellow chemical that is liquid at room temperature. It has a sweet odour and is highly flammable. Benzene is formed from both natural processes and human activities. Natural sources of benzene include volcanoes and forest fires. Benzene is also a natural part of crude oil, gasoline, and cigarette smoke. Normal environmental concentrations of benzene are unlikely to damage… Continue reading Benzene Pollution
Carbon nanotubes (CNTs) as carriers of drugs and artificial blood capillaries
Carbon nanotubes (CNTs) Carbon nanotubes (CNTs) are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms (graphene). They can be single-walled (SWCNT) with a diameter measured to less than 1 nanometer (nm). They are very lightweight, almost 1/6th of the steel with a mechanical tensile strength of almost 400 times that of steel.… Continue reading Carbon nanotubes (CNTs) as carriers of drugs and artificial blood capillaries
