DNA Extraction: A Virtual Lab: Dna Extraction Virtual Lab Answer Key
A virtual lab for DNA extraction is a computer-based simulation that allows students to experience the process of extracting DNA from cells without the need for physical materials or equipment. This type of lab offers several advantages over traditional hands-on labs, including increased safety, reduced costs, and the ability to explore a wider range of variables.
Materials and Equipment
- Virtual DNA extraction kit:This kit includes all the necessary virtual materials and equipment, such as a centrifuge, pipettes, and DNA extraction reagents.
- Computer with internet access:The virtual lab software requires a computer with internet access to run.
Procedure
- Prepare the cell lysate:Add the cells to a lysis buffer and vortex to break open the cells and release the DNA.
- Centrifuge the lysate:Spin the lysate in a centrifuge to separate the DNA from the other cell components.
- Extract the DNA:Add the DNA extraction reagents to the lysate and vortex to extract the DNA from the other cell components.
- Purify the DNA:Use a purification column to remove any remaining impurities from the DNA.
- Quantify the DNA:Use a spectrophotometer to measure the concentration of DNA in the sample.
Results
The results of the DNA extraction can be analyzed using a gel electrophoresis. The gel electrophoresis will separate the DNA fragments by size, and the size of the fragments can be used to identify the DNA.
Factors that can affect the results of the DNA extraction include the type of cells used, the age of the cells, and the method of DNA extraction.
