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

DNA Replication Deoxyribonucleic acid (DNA) contains the genetic instructions for the biological development of a cellular form of life including some viruses. DNA is an antiparallel double helix molecule with sugar-phosphate backbone on the outer side and nitrogen bases in the inner side. The bases are paired specifically‚ also known as complementary pairing‚ Adenine (A) with Thymine (T)‚ and Guanine (G) with Cytosine (C) by two and three hydrogen bonds‚ respectively. DNA is a long polymer

Homosexuality and DNA Honors Biology The human X and Y chromosomes have been completely sequenced. The X chromosome contains 153 million base pairs and harbors a total of 1168 genes. While the Y chromosome contains only 50 million base pairs and is estimated to contain about 251 genes. Educational institutions such as Baylor University‚ the Max Planck Institute‚ the Sanger Institute‚ Washington University in St. Louis‚ and others have spent countless hours and millions of research dollars

The Discovery Of The Electron The electron was discovered in 1895 by J.J. Thomson in the form of cathode rays‚ and was the first elementary particle to be identified. The electron is the lightest known particle which possesses an electric charge. Its rest mass is Me <approximately equal> 9.1 x 10 -28 g‚ about 1/1836 of the mass of the proton or neutron. The charge of the electron is -e = -4.8 x 10^-10 esu <elec trostatic unit). The sign of the electron’s charge is negative by convention‚ and

Guglielmo Marconi Through his experiments in wireless telegraphy‚ Nobel Prize-winning physicist and inventor Guglielmo Marconi developed the first effective system of radio communication. In 1899‚ he founded the Marconi Telegraph Company. In 1901‚ he successfully sent wireless signals across the Atlantic Ocean‚ disproving the dominant belief of the Earth’s curvature affecting transmission. Marconi shared with Karl Braun the 1909 Nobel Prize in Physics. A genies was born on April 25‚ 1874.Guglielmo

Scientist Practitioner Model Science the word itself is dominant around the world as almost all the theories and concepts in many subject areas are based on facts which are scientifically evident based. Psychology on the other hand presented as science in oxford dictionary definition. Reber (as cited in Henriques 2004) says that psychology cannot be defined but it is created by scientist to understand the human mind and behaviour. According to Henrique (2004) it is justifiable to define Psychology

The personal journey’s we undertake and the self-discoveries made along the way are what shape us into the people we become. In Robert Gray’s suite of poetry‚ in particular his poems ‘Journey: The North Coast’ and ‘Late Ferry’ as well as the film ‘Stand By Me’ directed by Rob Reiner‚ we discover that personal quests challenge beliefs and shape us into the people we are destined to be. In these three texts the composers‚ Gray and Reiner‚ through use of language and filmic techniques illustrate that
