DNA Extraction Lab Procedures

The video tutorial covers a DNA extraction lab, starting with a pre-lab activity involving a virtual lab where students answer questions and submit them for feedback. The main lab involves extracting DNA from cheek cells to create a DNA necklace. Instructions and materials needed for the lab are provided, including test tubes, solutions, and a pendant for the necklace.

What is the first step in the DNA extraction lab process?

• Performing the actual DNA extraction

• Creating a DNA necklace

• Completing a pre-lab activity

• Submitting the final report

Why is it recommended to take notes during the virtual lab?

• To avoid repeating the lab

• To share with classmates

• To answer the pre-lab questions accurately

• To remember the steps for the final exam

What should students do if they have questions during the virtual lab?
