  • DNA Molecules
    Deoxyribonucleic acid, or DNA, is the component containing the blueprint that specifies the biological development and composition of every form of life. Its general structure is in the form of a double helix and is primarily made up of nucleic acids. DNA is a polymer strand of nucleotides that contain sequences using genetic codes. For most complex cells, DNA is actually located in the cell nucleus. The physical model of the DNA molecule has always been a source of great mystery to a lot of people. How can a tiny molecule be responsible for carrying all genetic information?
  • Ozone Layer
    What is the ozone layer and what is its significance? Most of us have already heard of the terms "ozone layer" but do not really know or understand what it is. In simplest terms, the ozone layer is a layer of gas in the earth's atmosphere with relatively high concentrations of ozone gas. Although ozone gas also occurs close to the ground where it is known as a pollutant, 90 percent of ozone is found in the ozone layer. This layer of gas, found approximately 20-50 kilometres from the earth's surface, was discovered by French physicists Charles Fabry and Henri Buisson back in 1913.
  • Everything You Ever Wanted To Know About Ozone
    We often hear the word "ozone" especially in today's world where the environment is in danger due to pollution and other human excesses. But what exactly is ozone? Ozone is one of the many naturally occurring trace gases including methane, carbon dioxide and nitrous oxide that comprise the Earth's atmosphere. In geek terms, ozone is an allotrope of oxygen which means that its molecules consist of three oxygen atoms instead of the more stable O2.
  • Ozone Generator
    We all know that ozone is one of the most important gases present in the earth's atmosphere performing the very critical functions of blocking the harmful ultraviolet rays from reaching the earth's surface as well as helping keep the temperature of the earth's surface warm enough. But aside from these functions, ozone gas also plays a lesser task though no less important. Ozone is used as a disinfectant for air and drinking water and is used by many utilities for water and air treatment.
  • What You Need To Know About DNA
    In the last half of the 20th century, much research has been done on DNA, and this period has also been characterized by major breakthroughs in understanding DNA. For example, many insights have been discovered via the Human Genome Project,
