Biology 110 March 2‚ 2015 DNA Lab BACKGROUND In this laboratory experiment‚ students were introduced to DNA electrophoresis. DNA electrophoresis is an instrument that many forensic scientists use to get a DNA fingerprint as an evidence for crimes. Not only can it be used for forensic science‚ people can use this for paternity test‚ as well as look for evolutionary relationships among organisms. Agarose is used to make the gel that the DNA fragments are going into. Since DNA particles are negatively

DNA FINGERPRINTING LAB REPORT DNA contains genetic material and information that makes up each individual trait. Every person can be identified by providing his or her genetic information based on a particular DNA strand. DNA information is an effective way of identifying persons if it is used properly. It is used to identify humans in different situations such as crime scenes‚ accident scenes‚ paternity testing‚ soldier remain identification‚ inheritance claims‚ missing person investigations‚

Djina Jan-18-15 Lab #6 - DNA Extraction lab Introduction: DNA is a double stranded macromolecule composed of nucleotide bases pairing Adenine with Thymine and Cytosine with Guanine. S ince DNA is the blueprint for life‚ every living thing contains DNA. The extraction of DNA from cells and its purification are of primary importance to the field of biotechnology and forensics. Extraction and purification of DNA are the first steps in the analysis and manipulation of DNA that allow scientists to detect

Biotechnology Lab Report Lab: Extracting DNA from Bananas and Strawberries Purpose: To properly and successfully extract DNA from various fruits using cell disruption and separation techniques. Materials Used: 2 heavy duty zip-lock baggie 1 strawberry (fresh or frozen and thawed) 1 banana half 10 ml DNA extraction buffer* 2 Coffee filters Ice cold 95% ethanol 1 small beaker 2 Test tubes Wooden coffee stirrer *To make the extraction buffer‚ 100 ml of shampoo (without conditioner) was mixed

DNA extraction lab 1. A number of steps are required to isolate DNA from cellular content. Describe what happens at each step‚ and why it acts to separate the parts of the cell. The steps include a) breaking cell open to release the DNA; b) separating the DNA from cellar materials and proteins; c) using alcohol to precipitate the DNA; d) cleaning the DNA; e) confirming the presence of the DNA. a) Breaking cell open to release the DNA: the cells are separated from each other by physical means such

and analyzed various DNA fragments in order to determine if these DNA fragments originated from the same individual. The learning objective for this lab is to gain a better understanding of how DNA fingerprinting works. In this lab the primary function is to determine which DNA fragments match the DNA fragment found on the crime scene. To determine if any of the DNA fragments match the fragment found at the crime scene‚ the DNA fragments must undergo the DNA fingerprinting. DNA fingerprinting causes

Discussion Although only the extraction of strawberry DNA was performed in this lab‚ this section will address the roles of each step taken and the reagents used during the extraction of DNA from animal tissue as well‚ and compare it to the steps taken in the strawberry protocol. As described in the procedure using strawberries‚ the first step was to mash them into pulp using a mortar and pestle. The main goal from this physical disruption was to break the solid material consisting of any connective

The purpose of module E is to learn several DNA techniques in the lab including DNA purification with solubility and absorption‚ plasmid transfection of E.coli‚ colony screening by PCR and quantitative PCR. First part of the experiment E1 show the purification method of DNA through solubility. E. coli lysate mixed organic solvents to purify the DNA present in solution. First‚ the lysate was mixed with phenol/chloroform‚ then vortexed‚ and centrifuged. We extracted the aqueous layer and combined

this lab was to troubleshoot causes related to PCR components and develop an experiment that would test if the Taq amount is suitable for the PCR reaction to run correctly. INTRODUCTION Thermus aquaticus (Taq) DNA Polymerase is a bacterium that lives in thermophilic conditions and has been identified as an enzyme able to withstand the protein-denaturing conditions (high temperature) required during PCR (Noronha & Mullins‚ 1992). Why might you not be getting any bands on your PCR? If the Taq DNA polymerase
