does natural UVB radiation impact on the marine life? Ultraviolet-B radiation‚ also known as UVB‚ is a type of ultraviolet radiation forming a part of the electromagnetic spectrum (6). It is produced by high temperature surfaces in a continuous spectrum with the primary natural source being the sun. UVB radiation is harmful to living organisms and is only partially absorbed by the ozone layer of lower stratosphere(6). And due to ozone depletion in the recent decades‚ more UVB radiation reaches the surface

DNA Typing The discovery of the structure of DNA opened the realm of DNA technology and changed the way in which crimes can be solved. This is due to the fact that many criminals often unwittingly leave their DNA at crime scenes and/or the DNA of victims is carried away on the clothes of their assailants (Saferstein‚ 2015). Thus‚ by using DNA it is relatively easy to place individuals at crime scenes and discover key evidence. Before the 1980s‚ the courts primarily relied on testimony and eyewitness

Extract DNA from Anything Living |[pic] | |Introduction: [pic] Since DNA is the blueprint for life‚ everything living contains DNA. DNA isolation is one of the most basic and essential techniques in the study of DNA. The extraction of DNA from cells and its purification are of primary importance to the field of biotechnology and forensics. Extraction and purification of DNA are the first steps in the analysis and manipulation of DNA that allow scientists to detect genetic disorders‚ produce DNA fingerprints

DNA: A Forensics Science Tool Deoxyribonucleic acid commonly known as DNA is a genetic material found in the nucleus of cells in all living things. It is very useful in the world of science. Especially in the world of Forensic Science. DNA (Deoxyribonucleic acid) is a tool that is used daily by Forensic Scientists around the world. The discovery of DNA has been remarkable. Thanks to DNA many criminal cases worldwide have been solved. The first time DNA was used in a criminal case was in 1988

disagreements about the Government testing arrestees for DNA. Mandatory DNA testing is reasonable and legal by all terms. (Mandatory DNA Testing Is Constitutional 2). However‚ many have started to question it. The fourth amendment goes over privacy and personal rights‚ including unreasonable searches and seizures. Sarah B. Berson quoted in her online article‚ “DNA helps law enforcement investigate and prosecute crime‚ but the new trend of preconviction DNA collection raises serious Fourth Amendment issues

DNA extraction in Watermelon and Bananas Abstract During this experiment the researcher investigated the differing amounts of DNA present in bananas and watermelon. So that the researcher could do this‚ and accurately record the amounts‚ the researcher liquefied the fruits in a blender‚ added water and salt to them‚ and the added laundry detergent before using contact solution as an enzyme. Rubbing alcohol was then poured into the mixture and the DNA was extracted and

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

Comparison of side effects‚ limitations and risks. For the both ionising and non-ionising radiation there are many side effects‚ risks and limitations. In ionising radiation‚ there is a risk of cell mutation which can result in developing cancer if there is overexposure of the radiation to the patient’s. In the worst state this radiation can result in death. This type of radiation is not recommended to the groups of people like children‚ pregnant women or the elderly as it will expose them to higher
