Dna Technology Essay
DNA technology has provided law enforcement officers and investigators with a way to solve many crimes that would have previously been unsolvable. DNA technology has improved the way we solve crimes. Without DNA evidence in thousands of cases, the perpetrator would still be free, and innocent men would still be locked away. DNA technology has made solving crimes much more infallible and efficient. DNA, or deoxyribonucleic acid, is the fundamental building block of an individual's

Dna Gel Electrophoresis Lab
Introduction: Gel electrophoresis is a method used to separate DNA fragments based on size and charge. This technique uses a gel that acts like a filter with pores in which molecules travel through. There are two types of gel which can be used depending on the molecules being separated, polyacrylamide gel or agarose gel (Karcher, 1993). In this gel electrophoresis, 0.8% agarose gel is used (Rose, 2010). The gel is subjected to an electrical current

How Does a Dna Molecule Code for a Protein - Describe the Process Completely
1. How does a DNA molecule code for a protein. Describe the process completely. The process of creating a protein from the information given from DNA consists of two parts: transcription and translation. The first process transcription is copying the information from DNA to mRNA. The process starts when DNA double helix opens and in one strand a RNA polymerase attaches and starts to bind free nucleotides to DNA, so G bonds with C and

Single Base Extraction
Experiment #3: Single Based Extraction I. Introduction: The purpose of this lab is to separate a mixture of two compounds using acid-base extraction. The separation by extraction is based on differing solubilities of compounds in two immiscible liquids. The mixtures available for this lab contained a neutral compound and a carboxylic acid. The neutral compounds are benzophenone (Melting point 48-49 ⁰C), 1, 4-dimethoxybenzene (Melting point 58-59 ⁰C), biphenyl (Melting point 71-72 ⁰C), naphthalene (Melting point
