DNA extraction in Watermelon and Bananas Abstract During this experiment the researcher investigated the differing amounts of DNA present in bananas and watermelon. So that the researcher could do this‚ and accurately record the amounts‚ the researcher liquefied the fruits in a blender‚ added water and salt to them‚ and the added laundry detergent before using contact solution as an enzyme. Rubbing alcohol was then poured into the mixture and the DNA was extracted and

Extracting DNA from Human Cheek Cells: Conclusion The hypothesis of my experiment‚ if the strawberry DNA product was strandlike yet clumply then human epithelial cell DNA will be strandlike and clumpy too‚ was supported. This is because through the observations noted when the lab was being conducted‚ it can be seen that the human epithelical cell DNA was small‚ stringy‚ clumpy and squishy‚ just like the strawberry DNA product. Other observations of the human epithelial cell DNA was it was not only

I would not have achieved this far and this thesis would not have been completed without all the support that I have always received from her.

Brandon Schmetterer 3-13-15 Biology labs DNA Extraction Lab DNA is extracted from humans for genetic testing‚ for body identification‚ and for analysis of forensic evidence. The first step of DNA extraction is to take cheek cells from the test subject. Next‚ the cells must be burst open in order to release DNA. Third‚ DNA is separated from protein and debris. Lastly‚ the DNA must be isolated. A buccal swab is necessary in order to collect the cheek cells .The micropipettes are used to add lysis

Module 2 Section 2 EXPERIMENT: DNA & Protein Synthesis Exercise 1 – Modeling DNA 1. List the four bases which are found in DNA. (1 pt) The four bases found in DNA are cytosine‚ adenine‚ guanine and thymine. 2. Fit any six nucleotides together to form a row‚ then list the six nucleotides in the order you used them. Work with your model pieces and try fitting the bases together to make a double strand as shown in Figure 9 of the lab manual. Which nucleotides form

ISOLATION OF TRIMYRISTIN FROM NUTMEG ABSTRACT The purpose if the experiment was to extract the Trimyristan from ground nutmeg using extraction‚ distillation and recrystallization procedures. This experiment involves extraction and separation techniques that yield a purified product. The product was extracted and a distillation process was used to remove any remaining solvent. The recrystallization of the sample in turn produced a pure sample‚ which was proven using the known melting

Extraction of DNA from Cheek Cells Gene Smith February 29th 2013 INTRODUCTION DNA‚ deoxyribonucleic acid‚ is the genetic material of every living organism and is found in the nucleus of eukaryotic cells. DNA is often called the ‘blueprint for life’ because it contains the necessary information to carry out all the living processes of the cell (1).The purpose of this lab was to extract DNA from human cheek cells. The isolated DNA could be used inmapping or sequencing‚ PCR‚ crime scene investigation

This article from The Onion addresses the way that today’s scientific research is conducted and makes fun of how the source of funding for an experiment can influence its results. Interpreted plainly‚ the article claims that a new step has been added the scientific method: after a hypothesis is made‚ funding must be found. Then‚ based on who is funding the research and the sponsor’s desire‚ researchers must then align their study so it gets the results the funders want. The organization in charge

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

Jolyne Piet CHM-221L-02 Lab #2: Experimental Design Isolation of Sucrose: 3.01 g Panacetin were weighed in a 125-mL Erlenmeyer flask‚ and 51mL dichloromethane were added to partially dissolve the Panacetin. The insoluble portion was gravity filtered and air dried to yield 0.45 g of sucrose (15.0 % of original Panacetin). Isolation of Aspirin: The organic filtrate was extracted through a separatory funnel with 32 mL 5% sodium bicarbonate to produce an aqueous layer and a dichloromethane layer
