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

Electrophoresis and DNA fingerprinting Jani Lynette Hagen October 31‚2014 U74644799 Electrophoresis is a technique which uses an electric field to separate molecules‚ allowing for identification and characterization of the molecules. It is commonly used to separate nucleic acids and protein molecules of various sizes. To prepare the gel for electrophoresis the amount of agrose needed must be calculated. For a 0.8 percent gel 0.8 grams of agrose is necessary per 100 ml of buffer. The DNA fingerprinting

info in my DNA become my traits? This is a question that has been asked by many over the course of history.To answer this question we need to answer three essential questions‚ the first‚ how did we get our DNA‚ how did we go form one cell to trillions‚ and how did DNA become our traits. There is one essential driver to all of this‚ DNA‚ to understand DNA‚ we need to know what DNA is. DNA is two strands that contain genetic information in four bases‚ adenine‚ guanine‚ cytosine and thymine. DNA is located

Brandon Schmetterer 3-13-15 Biology labs DNA Extraction Lab DNA is extracted from humans for genetic testing‚ for body identification‚ and for analysis of forensic evidence. The first step of DNA extraction is to take cheek cells from the test subject. Next‚ the cells must be burst open in order to release DNA. Third‚ DNA is separated from protein and debris. Lastly‚ the DNA must be isolated. A buccal swab is necessary in order to collect the cheek cells .The micropipettes are used to add lysis

fermentation. In our lab we investigated alcoholic fermentation by using yeast‚ which can flourish in an low energy environment in anaerobic conditions. In this lab our goal was to discover the rate at which yeast will ferment different sized molecules of carbohydrates. In order to perform our experiment we made use of water‚ glucose‚ sucrose‚ and starch. It was hypothesized that glucose‚ sucrose‚ then starch would all be used to produce energy during fermentation. Being that glucose is a simple

Physical Properties of Organic Molecules Abstract Identifying the physical properties of compounds can be useful in several ways. It helps us to determine the structure of certain compounds‚ the purity of substances and if a substance is not pure we can figure out how to separate contaminating substances from a compound. In this experiment‚ I learned how to determine a solid’s melting point and why some melting point ranges may be broader than others.

Over the last three decades the importance of DNA in the dispensing of just has been on a constant rise. Deoxyribonucleic acid‚ most commonly known as DNA‚ is a molecule found in every living organism. DNA is responsible for storing an individual’s genes. As an investigative tool DNA is a very useful tool as it can be used to identify persons of interest relevant to particular crime scenes (McEwen‚ T. 2011). DNA alone is not able to help identify how someone looks or their characteristics; however
