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

Strawberry DNA lab Extraction Purpose: The purpose of this lab experiment is to see if this particular type of fruit which in this case is a strawberry contains DNA. Using materials such as a Ziploc bag to help keep the entire strawberry in one place while it gets smashed and test tube to help better see the DNA and break down of the liquid in the left over strawberry sediments. Background information: The long thick fibers of DNA store the information for the function of the chemistry

extract DNA from a strawberry using limited household items. This was accomplished with the prior knowledge that the DNA is stored in the nucleus of the cell‚ and that is an extraction buffer would be needed to acquire the DNA. This experiment had no control group‚ however‚ if there was a control group it might be a group with no extraction buffer. The independent variable in this experiment is the extraction buffer. The dependent variable in this experiment is the ability to extract DNA. The constants

DNA extraction and purification is an essential tool in understanding the biological basis and significance of a eukaryotic cell. Its role is pivotal to numerous scientific applications ranging from basic science research to applied research. Hence‚ DNA is found in all living organisms. Fragaria x ananassa‚ also known as a strawberry has been widely used as one of the many biological models in studying DNA structures due to its accessibility. Strawberries are octoploid which contain large genomes

Strawberry DNA Extraction Donovan Roberts Mrs. Caudill Honors Biology 3/7/11 Introduction The structure of DNA is made of nitrogenous bases‚ phosphate groups‚ and sugars. These three parts of DNA form hydrogen bonds and create a right-handed double helix. The location of DNA in a eukaryotic cell is found within the nucleus‚ bound to proteins. DNA can be extracted from within the cell. They are several steps you must take to retrieve DNA from within the cell. When extracting DNA cells

The hypothesis for this lab is if strawberry DNA is separated from other components‚ then when it is placed in a insoluble solution the DNA can eventually be isolated. DNA is deoxyribonucleic acid. Its a self replacing material present in all living organisms as the main constituent of chromosomes. It is the fundamental and distinctive characteristics of someone or something‚ especially when regarded as unchangeable. DNA extraction is the removal of deoxyribonucleic acid from the cells or viruses

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

Berry DNA Extraction Lab I. Problem Statement: Successfully extracting the DNA from strawberries. II. Background info: DNA is the genetic information in organisms that codes for proteins‚ and controls the cells function. The DNA is a double helix molecule that is formed by various nucleotides which include Adenine‚ Thymine‚ Guanine‚ and Cytosine with sugar phosphate. Different organisms can have larger or smaller genes. DNA is also what makes up chromosomes during cell replication. Strawberries

DNA Extraction Lab 1/17/14 Purpose : This lab was conducted in order to show and analyze the way DNA is extracted. Hypothesis: If the lab is conducted properly then we should be able to view a visible amount of DNA from the strawberry and detergent mixture. Variables: The independent variable in this experiment is the strawberry mixture while the dependent
