DNA databases In 1992‚ The United States‚ Federal Bureau of Investigation funded the Combined DNA Index System (CODIS). It is a computer system that stores DNA profiles created by federal‚ state‚ and local crime laboratories in the United States‚ with the ability to search the database in its entirety; it also helps agencies identify suspects of crime. The origin of CODIS is attributed to the Scientific Working groups (SWG) that began in the late 80’s. SWG was backed by the FBI Laboratory which

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

It is true that in many regards‚ modern liberalism has indeed rejected certain aspects of the classical liberalist approach‚ within such topics as individualism‚ freedom and justice. However‚ it would foolish to argue that they had abandoned it completely‚ as some elements have survived. Classical liberals believe in negative freedom. This is the simple belief in an absence of external constraints on the individual and that they should be left alone to make their own choices. In this way classical

Objective : To extract the DNA from onion samples. Introduction : Nuclues has DNA molecule in it. It is packaged into thread like structure known as chromosomes. Each and every chromosome is made up of DNA tightly coiled many times around proteins which is known as histones. Histones supports the structure. Chromosome cannot be visible even under the microscope if the cells are not dividing. DNA consist of 2 long polynucleotide which is composed of 4 types of nucleotide units. Nucleotides

Have we become slaves of technology? Technology can be defined as a body of knowledge used to create tools‚ develop skills‚ and extract or collect materials; the application of science (the combination of the scientific method and material) to meet an objective or solve a problem. In other words the application of scientific advances to benefit humanity. It influences minds in good and bad ways‚ and it allows people to share information which they would otherwise not be able to attain. Even if a

General Biology DNA and RNA Deoxyribonucleic Acid and Ribonucleic Acid • DNA is deoxyribonucleic acid. It is located in the nuclei of cells‚ which make up the body. Consequently‚ DNA can be considered as one of the building blocks of the body. Where is DNA found? DNA‚ or deoxyribonucleic acid‚ is the hereditary material that lies within the nucleus of all cells in humans and other living organisms. Most of the DNA is placed within the nucleus and is called nuclear DNA. However‚

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
