What is the hypothesis of DNA extraction lab?
My hypothesis for this project was if Tide laundry detergent is used in the DNA extraction liquid, then you will extract more strawberry DNA than with any other detergent. The constant in my experiment was the amount of strawberries used in the experiment.
What is the purpose of the strawberry DNA extraction lab?
Background: 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.
How do you extract DNA from a strawberry step by step?
Experimental Procedure:
- STEP 1: Mix the DNA Extraction Liquid. Take 1 plastic cup and mix together 2 teaspoons of dish detergent.
- STEP 2: Get the DNA.
- STEP 3: Separate the Fluids from the Solids.
- STEP 4: Extract the DNA.
- STEP 5: Measure the Amount of Extractable DNA.
- STEP 6: Repeat Process with Other Types of Strawberries.
What can scientist learn about strawberries by extracting the DNA?
While other fruits are soft and just as easy to pulverize, strawberries are the perfect choice for a DNA extraction lab for two very good reasons: (1) they yield way more DNA than other fruits, and (2) they are octoploid, meaning that they have eight copies of each type of DNA chromosome.
What is the purpose of DNA extraction lab?
This DNA extraction laboratory is an activity to facilitate learning about cells and the structures inside of them. All living things are made of cells. Inside cells are smaller structures called organelles that work to perform different functions, or jobs, within the cell.
Where was the DNA in the strawberry?
Observe the line between the strawberry mixture and the alcohol. You will notice a white thread-like cloud appearing at this line. This is strawberry DNA. The DNA will clump together and float to the top of the alcohol layer.
Why is it easy to extract DNA from bananas?
Explain that crushing the bananas separates its cells and exposes them to the soap and salt. The soap helps break down cell membranes and release DNA. The salt helps bring the DNA together, and the cold alcohol helps the DNA precipitate and come out of solution so it can be collected. 2.
How do you extract DNA from a strawberry?
HOW TO EXTRACT STRAWBERRY DNA. Chill the alcohol in the freezer. Remove the green stems from the strawberries and add to the bag. Squish the strawberries into a pulp. Add 1 tablespoon of dish soap , a teaspoon of salt, and 1/3 of a cup of water to the bag. Mix. Line the test tube with the coffee filter. Pour the strawberry liquid into the test tube.
Why do Strawberry cells need DNA?
Strawberries have DNA because the DNA serves as an instruction manual in order for the strawberry cells in properly function. Strawberries were used in this experiment because they have more DNA than any other fruits. Also, strawberries are octoploids, meaning that there are eight copies of DNA.
What is the hypothesis for Strawberry DNA?
DNA STRAWBERRY CONCLUSION. 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.
What is the DNA extraction of a strawberry?
DNA Extraction – Strawberry. Strawberries are octoploid, which means they have eight sets of chromosomes. The procedure for extracting DNA from a strawberry is simple, and the results are usually obvious, it is easy to see the white strands of DNA within the pink solution of strawberry juice.
