Evaluation of techniques for Dental and DNA identification for mass disaster victim Introduction: A mass disaster is an unanticipated event that results in serious injury and death to a large number of people. Mass disaster can be categorised into three categories‚ natural disasters‚ accidental disasters or even intentional terrorism acts. Natural disasters could include events such as earthquake‚ flooding or tsunamis. Accidental disasters could be associated with events aircraft‚ ship

DNA bender: Cren7 & Sul7 DNA benders can introduce a bend in the DNA (Luijsterburg et al.‚ 2008). Many bends in the DNA automatically provide compaction of the DNA. Two important DNA bending proteins in crenarchaea are Cren7 and Sul7 (Driessen et al.‚ 2013). They are similar in structure‚ but they have different DNA binding regions (Zhang et al.‚ 2015). Cren7 and Sul7 can be methylated at several lysine residues (Guo‚ 2007). This PTM might be to regulate gene expression (Feng et al.‚ 2010)‚ although

How DNA Is Unwound So That Its Code Can Be Read DNA can be found in every living organism. “[It is] the material inside the nucleus of cells that carries genetic information” (Your Genes‚ Your Choices: Glossary). The genetic information is consisted of two strands twisted together and is encoded in the sequence of nucleotides‚ which are deoxyribose‚ phosphate group‚ and nitrogen bases. This genetic information is also heritable traits which can be carried onto future offsprings. In an article

BMS 424 Chapter 1 DNA‚ RNA‚ Historical Experiments & Structures Frederick Griffith Experiments with Streptococcus pneumoniae S. pneumoniae comes in two strains‚ smooth and rough strains S Smooth : Secrete a polysaccharide capsule; Protects bacterium from immune system of hosts; Produce smooth colonies on solid media. R Rough : Unable to form capsule; Produce colonies with a rough appearance. Griffith conducted experiments in 1928 using two strains of S. pneumoniae: type IIIS and type IIR :

Procedure 2: DNA Extraction from Cheek Cells Materials: Water‚ Clear Dish Soap‚ Table Salt‚ Isopropyl Alcohol (70%) or Ethanol‚ Food Coloring 1. To 200 Ml drinking water add two teaspoons of salt 2. Gargle the salt water for 1 minute. 3. Spit the gargled water into a beaker (or new cup). Now your cheek cells are suspended in the salt water. 4. Gently stir the salt water with one drop of soap (try to avoid air bubbles) 5. In a separate beaker (or cup)‚ mix 20 ml isopropyl alcohol and 1-3 drops

DNA is the primary genetic material that makes each individual different. DNA is the molecule that makes up chromosomes each pair of chromosomes contains DNA from one parent. DNA is found in the nuclei of eukaryotic cells and prokaryotic cells in living organisms. DNA is so important it is unable to leave the nucleus therefore the body makes RNA to carry information out into the cytoplasm. The three major components of DNA nucleotide monomers are phosphate‚ 5 carbon ring sugar (de-oxyribose) and
