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‚

to amplify DNA fragments using PCR (polymerase chain reaction) and then separate the products on the basis of size using agarose gel electrophoresis in an emulation of DNA fingerprinting. The task‚ which was successfully carried out was to determine whether DNA from suspects A‚ B or C matches the sample of blood found at the murder scene (X). The process of PCR acts in the same way as DNA replication but is restricted to specific DNA samples of interest. By amplifying the necessary DNA sequence‚

create a DNA profile in this experiment were PCR and gel electrophoresis. The PCR is used to amplify the several DNA samples and gel electrophoresis is performed to separate the DNA fragments according to their size. [6] In the first part of the experiment‚ PCR amplification of the DNA templates was performed and the products obtained were used to perform gel electrophoresis. The process of PCR allows for the amplification of the DNA samples and the components needed to perform PCR are template DNA‚ DNA

Agarose gel electrophoresis is a technique used in the laboratory to separate macromolecules such as nucleic acids and proteins. Electrophoresis can take a mixture of macromolecules of different molecular weights‚ shapes‚ and various electrical charges to determine all the various compounds in the mixture and allowing for further purification that can aid in details of individual elements of the mixture being studied. Agarose gel electrophoresis is a very important technique used in the field of

In this experiment we used gel electrophoresis to separate goat‚ sheep‚ cow‚ horse‚ chicken serum along with cow transferrin and cow gamma globulins. In this lab we successfully prepared the gel electrophoresis bed and successfully separated the proteins. The western blot along with the nitrocellulose blot was successful but produced no visible results. Introduction: Amino acids are basic units and building blocks of proteins. They consist of an amine group‚ a carboxylic group and side chain.

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 the sugar-phosphate

Gel Electrophoresis is used to separate the haemoglobin component of blood. Because each type of haemoglobin (HbA‚ HbS‚ Hbc and more) have different electrical charges‚ they will separate after undergoing gel electrophoresis. Firstly‚ a blood sample from the patient is taken and is applied to a cellulose acetate membrane strip that has been soaked in a buffer solution along with saponin. The red blood cells are lysed by the saponin while being soaked‚ therefore they release their haemoglobin. A

Gel Electrophoresis Lab SBI4U1 May 13th‚ 2013 Gel Electrophoresis Lab Purpose: The purpose of this lab is to learn how restriction enzymes cut DNA molecules at specific sequences‚ thus producing DNA fragments of various lengths. Students learn how fragments form unique patterns‚ which help to distinguish the base for DNA identification. This lab answers the question “whose DNA was left behind?”. Materials: * Transfer pipets * Agarose Gel * Dyed DNA samples *

Function 16 October 2014 Gel Filtration and Electrophoresis Objective The essential goal of the experiment was to separate proteins in a solution based on size in different fractions. The relative protein content for each one fraction was found through the utilization of an amido black-based protein assay. Later in the trial polyacrylamide gel electrophoresis was utilized to separate BSA from hemoglobin. Methods I. Gel Filtration and Protein Assay: 1. A slurry of Bio-Gel P-100 beads in water was

Bio 1 Lab: Electrophoresis and DNA fingerprinting Jani Lynette Hagen October 31‚2014 U74644799 Electrophoresis is a technique which uses an electric field to separate molecules‚ allowing for identification and characterization of the molecules. It is commonly used to separate nucleic acids and protein molecules of various sizes. To prepare the gel for electrophoresis the amount of agrose needed must be calculated. For a 0.8 percent gel 0.8 grams of agrose is necessary per 100 ml of buffer. The DNA
