We wanted to extract‚ see and analyze DNA from a single strawberry( 12.11 g). The long‚ thick fibers of DNA store the information for the functioning of the chemistry of life. DNA is present in every cell of plants and animals. The DNA found in strawberry cells can be extracted using common‚ everyday materials. To start the procedure we needed the following supplies; one strawberry‚ one plastic cup‚ 10 ml of Cell Lysis Buffer (10% detergent‚ 1% NaCl)‚ one plastic zip-lock bag‚ one coffee filter‚

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

Procedure 2: DNA Extraction from Cheek Cells Materials: Water‚ Clear Dish Soap‚ Table Salt‚ Isopropyl Alcohol (70%) or Ethanol‚ Food Coloring 1. To 200 Ml drinking water add two teaspoons of salt 2. Gargle the salt water for 1 minute. 3. Spit the gargled water into a beaker (or new cup). Now your cheek cells are suspended in the salt water. 4. Gently stir the salt water with one drop of soap (try to avoid air bubbles) 5. In a separate beaker (or cup)‚ mix 20 ml isopropyl alcohol and 1-3 drops

Biology Abstract In this experiment we used dried split peas to extract the DNA and observed the protein isolate. Introduction The purpose of the experiment was to learn what the process was to extract DNA. You also learned the characteristics of DNA and go to observe them. Hypothesis I think the DNA will be really interesting to observe. Procedure Material: * Alcohol * Blender * Water * Drinking glasses * Measuring cup * Paper towels * Freezer
Premium Experiment Scientific method Hypothesis
the Extraction lab is to separate and purify benzoic acid‚ 2-naphthol‚ and naphthalene. These organic solids are purified by partitioning the solid in 2 immiscible solvents‚ diethyl ether and sodium bicarbonate or sodium hydroxide. II. Significance a. The significance of the Extraction lab is to purify Acetanilide benzoic acid‚ 2-naphthol‚ and naphthalene by determining the partition coefficient. This value is determined by dividing the solubility of the given solute in the extraction solvent

Extraction Separation of a Carboxylic Acid‚ a Phenol‚ and a Neutral Substance Purpose The objective of the experiment is to identify the three substances in the mixture and to determine the percent recovery of each from the mixture. The unknown will consist of either benzoic acid or 2-chlorobenzoic acid‚ 4-t-butyl phenol. Determine the weight of crystals and also the percent yield Introduction There are various techniques of extractions‚ solid/liquid extraction‚ which

Extraction and Analysis of Plasmid DNA from E. coli Cells Introduction A plasmid is an extra-chromosomal element‚ often a circular DNA. Since a plasmid is by definition an extra-chromosomal element‚ it cannot make use of any origin of DNA replication in a chromosome (BP site). Meaning that DNA synthesis within a plasmid depends on having an origin of DNA synthesis of its own. Plasmids are often found in bacterial cells‚ in which they are used as transfer agents for transmitting various antibiotic

Activity Pg. 63: The Princess and the Pea In the fairy tale‚ The Princess and the Pea‚ by Hans Christian Anderson‚ a Prince is in search of a Princess for her hand in marriage‚ but there are many “Princesses‚” and he only wants to marry a real princess. In the exposition of this fairy tale‚ there is a Prince who has traveled all around the world in search of a real Princess to marry‚ but unfortunately every Princess he comes across is not the real Princess he wants. The Prince then returns home
Premium Hans Christian Andersen Fiction Narratology
Princess and the pea didn’t have a bipolar for a stepfather. Can you see it? Her in her royal pink nightdress‚ awakened by the turbulence of shotgun shells atop the tile floor. A shotgun makes more of an impact than you think‚ but if she is pestered by a pea‚ I’m pretty sure she wouldn’t have survived this story. Sometimes I wonder if the tickling in my back in the morning is that shell reminding me that if it was a little more keen I probably either wouldn’t be here or writing this by the air pulses

EXPERIMENT 13： Extraction: Extraction with acid and alkali Objective 1. To recover the benzoic acid and p-dichlorobenzene from its mixture from its mixture by using acid-alkali extraction. 2. To determine the percentage recovery and melting point of the recovered benzoic acid and p-dichlorobenzene. Introduction Acid-base extraction is a process which purifying the acids and bases from mixtures based on their chemical properties. Acid-base extraction is performed to isolate the compounds and natural
