DNA Profiling for Crime Investigation Rabia Awan Preston University Islamabad‚ Pakistan rabiawan079@gmail.com Abstract— DNA profiling also called as DNA typing or Gene fingerprinting has been used as a powerful process for identification of humans. Many countries around the world where forensic databases have created to store DNA patterns(DNA profiles) of crime scenes in order to put the actual criminals behind the bars and free the innocent who have been kept in jails for years without any

This experiment was performed to demonstrate a cycle of chemical reactions involving copper. This lab will start with copper as a reactant in the first reaction through a series of five chemical forms of aqueous phase reactions and ending to calculate the percentage of recovered solid copper as a product in the last reaction of the experiment. The experiment resulted in a percent recovery from the cycle of copper reactions of an increase to 139%. . Introduction: The purpose of this experiment is

A microprocessor incorporates the functions of a computer’s central processing unit (CPU) on a single integrated circuit (IC)‚ or at most a few integrated circuits. It is a multipurpose‚ programmable device that accepts digital data as input‚ processes it according to instructions stored in its memory‚ and provides results as output. It is an example of sequential digital logic‚ as it has internal memory. Microprocessors operate on numbers and symbols represented in the binary numeral system. The

2. The Criminal investigation Process Police powers You should be mindful of the fact that the exercise of police authority is regulated. The main police powers are defined by statutes including the: Law Enforcement (Powers and Responsibilities.) Act 2002. (LEPRA) and the Bail Act. 1978 NSW Police powers include: 1. The power to arrest (discussed in more detail below). 2. The power to issue cautions‚ warnings and infringement notices in relation to minor offences. 3. The right to obtain

The error in this step was caused by the variable heating of the solution to prevent bubbling of the solution. The reaction of copper with nitric acid resulted in a brown toxic gas‚ As the copper dissolved‚ the solution slowly turned blue because of the copper ions. this is the balanced equation for the reaction Cu(s) + 4H+(aq) + 2NO3-(aq)---> Cu2+(aq) +2NO2(g) + 2H2O(l) The reaction of aq copper nitrate with sodium hydroxide was the turning of the solution to a blue color‚ when water was added a

Photosynthesis Essay During the Light Dependent Reactions‚ activity occurs within the thylakoids of the chloroplast. NADP+ accepts two high energy electrons and an H+ ion and then converts into NADPH. This process ultimately traps some of the sunlight in chemical form. Then‚ NADPH is able to carry the energy it absorbs to the rest of the cell. The reaction produces O2 gas and converts ADP to ATP and NADP+ to NADPH. First‚ pigments in Photosystem II absorb light‚ which is then absorbed by electrons
