It’s all around us. Radiation is categorized into two groups: ionizing‚ and non-ionizing. Ionizing radiation consists of particles‚ gamma rays‚ or X-rays with sufficient energy to create ionization in the medium it passes through. It has enough energy so that while an interaction with an atom takes place it can withdraw tightly bound electrons from an atom‚ thus making the atom charged or ionized. It includes alpha particles‚ beta particles‚ and gamma rays. Ionizing radiation has made a large impact

When Charles Wiley first opened his small printing shop in lower Manhattan in 1807‚ it was a generation of boundless potential searching for an identity. And we were there‚ helping to define a new American literary tradition. Over half a century later‚ in the midst of the Second Industrial Revolution‚ it was a generation focused on building

DNA is a tool of great use throughout the world. Especially when it comes to the field of forensic science‚ DNA is the most important tool of all. What is DNA? DNA‚ short for deoxyribonucleic acid‚ is a group of molecules that hereditary information in which guides development and functioning throughout the body. “DNA is to justice as a telescope is to the stars; not a lesson in biochemistry‚ not a display of the wonders of magnifying glass‚ but a way to see things as they really are.”(Barry Scheck

what part of your DNA really comes from your mom? Or which part comes from your dad? The answers to these questions can easily be found out with DNA Fingerprinting. Created in 1984‚ DNA Fingerprinting has become a major importance to the world by helping find the criminal in a case‚ figuring out who the father is when unknown‚ and finding the identification of an unknown body. DNA Fingerprinting can be taken from simple things like a strand of hair or even a dried bloodstain. DNA is everywhere‚ and

DNA‚ which stands for Deoxyribonucleic acid is a nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms. The main role of DNA molecules is the long-term storage of information. These nucleic acids consist of long chains if chemical units called nucleotides. Nucleic acids are information storage molecules that provide the directions for building proteins. Described by the DNA testing centre‚ Inc.‚ “DNA is found inside the chromosome

Anne Holt DNA Profiling Introduction: DNA Profiling was authorised in the mid- 1980s. DNA is short for deoxyribonucleic acid. DNA accommodates a genetic code for each organism. DNA profiling is not just used for identifying fingerprints and such‚ it is also used for identifying any type of evidence that has DNA in it. Auspiciously‚ each DNA is unique‚ not even siblings have indistinguishable DNA‚ unless they are identical twins. USES OF TECHNIQUE: DNA profiling is used most often to solve crime

Carbohydrates have two major functions in plants and animals: they serve as fuel and building material. Plants store most of their energy in the form of starch. Starch is a polysaccharide (consisting of several conjoined sugars). Synthesizing starch enables the plant to stockpile surplus glucose‚ and since glucose is a major cellular fuel‚ starch represents stored energy. The sugar can later be withdrawn by hydrolysis‚ which breaks the bonds between monomers. Animals‚ in turn‚ have enzymes that

Using agarose gel electrophoresis is to separate and visualize the DNA fragment‚ which is produced by restriction enzymes . Introduction: The purpose of this experiment is to measure the size of the fragments of DNA and separate
