DNA extraction is a common laboratory technique used to isolate and purify DNA from a variety of sources. In this lab, we will be extracting DNA from strawberries using household materials. This is a fun and easy way to learn about DNA extraction and see the DNA of a common fruit with your own eyes.
Before we begin the lab, let's consider some questions that we might have about the process of DNA extraction from strawberries:
What is DNA and why is it important?
DNA, or deoxyribonucleic acid, is a long, double-stranded molecule that carries the genetic information of an organism. It is made up of four nucleotide bases: adenine (A), guanine (G), cytosine (C), and thymine (T). The specific sequence of these bases determines the genetic information of an organism, and this information is used to control the development, function, and reproduction of all living things.
How do we extract DNA from strawberries?
To extract DNA from strawberries, we will first need to puree the strawberries in a blender or food processor. We will then add a mixture of salt and detergent to the puree, which helps to break down the cell membranes and release the DNA from the cells. Next, we will add rubbing alcohol to the mixture, which causes the DNA to form into a white, stringy substance that can be easily seen and collected.
What household materials do we need for this lab?
For this lab, you will need a blender or food processor, a bowl, a spoon, a strainer, a piece of cheesecloth or a coffee filter, a beaker or a cup, rubbing alcohol, salt, and detergent. You will also need a few strawberries and some ice.
What can we learn from extracting DNA from strawberries?
By extracting DNA from strawberries, we can learn about the structure and function of DNA and how it is involved in the characteristics and traits of living organisms. We can also learn about the role of enzymes in breaking down cell membranes and releasing DNA, and how different chemicals can be used to isolate and purify DNA. This lab can also be a fun and engaging way to introduce students to the world of biotechnology and the many ways in which DNA is used in scientific research and medicine.

The study of DNA is used in so many different ways by scientists all over the world. When they study DNA they can learn about extinct species like dinosaurs , they can create vaccines and medications, they can use DNA to solve crimes, and so much more. It lives in a cells nucleus in pairs called chromosomes. That said, once your students have mastered extracting DNA from strawberries, why not challenge them to see if they can extract the DNA from other fruit? Hypothesis 1 : Looking through the instructions, I believe that pulverising the strawberry and getting the juices will help the alcohol extract the DNA better. Based on what we have learned in our previous discussions, I think DNA would look like little circles under a microscope. Extraction of DNA from a Strawberry Background Deoxyribonucleic acid DNA is a molecule that encodes genetic instructions.

Once mashed, add 20mL of the extraction liquid. Place plant material into a zip-loc bag and add the extraction mixture. Pour about a tablespoon of the cold isopropyl alcohol into the cup. Most of all she loves research and figuring out how things work, and sharing that knowledge with others. DNA of the Strawberries. The cell formation of strawberries is different compared to others. Strawberries are easy to pulverize and contain enzymes called pectinases and cellulases that help break down cell walls to expose DNA, making it a perfect organism to extract DNA from.

Supplies and Materials Ripe strawberries a little over ripe is even better! Creating the Extraction Mixture 1. How does Strawberry DNA Extraction Work? DNA is a molecule that is like a little recipe for life and holds all the information your body needs to function. Make the extraction buffer — a. As an Amazon Associate I earn from qualifying purchases. With this experiment we give students the chance to work with DNA and make this important part of all life forms a more tangible concept.

Keeping the DNA in the nucleus allows the DNA to be protected and keep it from escaping. How is the thread and spool an analogy for what happened to the DNA when we added the alcohol. If you use frozen, make sure they are completely thawed. We crushed the strawberries for us to be able to break down the cell wall and other parts of the cell, enabling us to see the DNA at the end of the experiment. Humans have 46 chromosomes arranged in 23 pairs.

Use your fingers and palms to mash it. Bananas, kiwis and even oatmeal are great options! Once we put in the alcohol the DNA moved to the top and clumped together and made it easier to see like if you add in a length of thread to the sewing thread. This simple strawberry DNA extraction lab is a cool lesson in how so many of the living organisms on this planet are made up of DNA! Put the strawberries in plastic bag, push out all air, and use your hands to mash the strawberries for 2 minutes 4. Today we are doing a kitchen science experiment that allows us to see DNA! It would also be better if all the DNA was kept in one area rather than floating in the cytoplasm. This experiment is an incredible biology lab for students in Upper Elementary through High School. Read more simple DNA science below to share with your kiddos… EXTRACTING STRAWBERRY DNA Each individual cell in an organism has a copy of the DNA pattern used to reproduce that cell.

Close the bag slowly, pushing all of the air out of the bag as you seal it. If I could mix strawberries with salt, ethanol and laundry detergent, then I could extract DNA and see clearly. DNA is our genetic code. Ourcells have two copies of theirDNA whilestrawberry cells have eight! At the same time, by crushing the strawberries, we made this liquid consistency which is easier to filter and work with. Disclaimer: This article may contain commission or affiliate links. Then we created a slide with our strawberry DNA and looked at it under the microscope.

Why Do Strawberry DNA Extraction? To this day, scientists all over the world are continually working to unlock the secrets hidden the DNA code of our cells. Obtain one to three fresh strawberry ies you can also use a piece of banana , and remove the green sepals from the top. Scientists can study it more closely and find out the DNA sequencing a structure + characteristics of the particular organism. Pour the mixture through the strainer into the glass until all the liquid is in the glass 6. Sewing thread is very thin and difficult to see once a length of thread is removed from the spool. Check out our Your kids can have an up close look at strawberry DNA! DNA is a double helix with the two strands chemically linked like a spiral shaped ladder. This is such an incredible biology science lab to do with your students.

A diploid cell means that it only has two copies of the chromosomes inside the cell. Grab a magnifying glass and check it out. This will help isolate the DNA on the surface of the mixture. DNA molecules consist of two polymer strands coiled around each other to form a double helix. By getting a better understanding of DNA, scientists can apply that info to other things such as the search of life in foreign plants, the re-creation of life and finding cures 2. Being careful not to break the bag, thoroughly mash the strawberry with your hands for 2 minutes. Mash it around for one more minute.
