and the number and size of DNA pieces that will be left behind. These pieces can then be separated and compared using the process of gel electrophoresis. As these fragments move‚ their varying lengths propel them through the gel at different speeds. Scientists can use these RFLPs‚ Restriction Fragment Length Polymorphisms‚ a set of DNA puzzle pieces unique to only you‚ to create a pattern called a DNA fingerprint. Similar to the unique

Criminal evidence is any exhibit or testimony regarding a crime. It can take many forms‚ and is typically used to establish that a crime has been committed and identify blame or fault in a criminal case. What constitutes acceptable criminal evidence varies somewhat between legal systems‚ although ideally‚ evidence provides reasonably reliable information that gives a more complete picture of a crime The outcome of many criminal law cases will depend upon the strength and admissibility of evidence

This particular gel is 0.8% agarose. Figure 2: Restriction Fragment Length Polymorphism of Circular DNA. Experiment which resulting this figure is done in Bio 22 lab on April 6‚ 2012. This figure represents several data that are obtained from adding certain restriction enzyme. Lane #1 represents a ladder‚ a marker of known

one must conduct these tests carefully. A technique called Polymerase Chain Reaction (PCR) is used to make millions of copies of the DNA without destroying it. Then‚ a restriction enzyme cuts the DNA into different fragments called reaction fragment length polymorphisms (RFLPs) at specific binding sites. Gel electrophoresis is used to move the RLPF fragments from the negative to positive pole using an electrical charge. The movement of the RFLP fragments distance depends on their size and shape; therefore

The Rate of Locomotion dependence on hind leg length and body mass for the Tenebrio molitor beetle. Abstract The effects of leg length and body mass on the Tenebrio Molitor’s rate of locomotion were investigated under laboratory conditions. The performance (running speed) was accessed for 37 Tenebrio molitor with different hind leg lengths and body masses. Running speed is important for a variety of activities (e.g. searching for prey and mates‚ dispersal‚ etc.). Therefore‚ increased

FORENSICS Forensics‚ by and large‚ is the application of science to the legal process. It is an emerging research domain in India. There are many different types of forensic sciences baring their vital presence possibly in every field of human endeavor. Of these‚ let us now discuss about the computational‚ cyber and the DNA forensics. COMPUTATIONAL FORENSICS: The development of computational methods or mathematical and software techniques to solve forensic issues is called computational forensics

The Importance of DNA Evidence What is DNA? Is it these winding strands that look like ladders or is it what gives a person blonde hair and blue eyes? Actually‚ DNA is both of these things. DNA is a person’s genetic makeup–their hereditary blueprint passed on by their parents. It is a part of almost every cell in the human body. In each cell‚ a person’s DNA is the same; it stays the same throughout their lifetime. DNA is found in skin tissue‚ sweat‚ bone‚ the root and shaft of hair‚ earwax‚ mucus

Investigation: how the resistance in a circuit varies with the length‚ thickness and type of wire Introduction A current is a flow of negative electrons around a circuit or electrical pathway. This is measured in how many electrons per second or the charge they are carrying go round the circuit (amps or amperes) Voltage or Potential Difference measures how much energy individual electrons have to use up as they go around a circuit. (Volts) Components in a circuit have a Resistance value which

Does DNA profiling in its current state offer foolproof identification? What needs to be in place for it to be error-free? Should all incarcerated criminals be forced to give samples? Should convicted juveniles? Should the general public be required to give a DNA sample? The pros of DNA profiling are that it can be used to quickly eliminate a suspect‚ saving time in searches for perpetrators. And it can provide compelling evidence to support a conviction and‚ most importantly‚ reduce the chances
