Forensic DNA Analysis

Показать описание
As humans, we share most of our DNA with each other, but how do we determine the differences between our individual DNA sequences? Restriction enzymes are proteins that recognize specific DNA sequences and can be used to determine whether a particular DNA sequence is present. Join DNALC instructor Allison as she introduces restriction enzymes and gel electrophoresis. She will also walk you through an example of how DNA collected from a crime scene could be used to identify the person who left their DNA at the scene!

In this DNALC Live session, you will:
• Learn about restriction enzymes
• Watch a time-lapse video of DNA fragments being separated through a gel
• Determine who left their DNA at a “crime scene”

Presenter: Allison Mayle
Audience: Grades 7-9 and interested science enthusiasts

This is one of the best explanations of gel electrophoresis I’ve ever seen, bravo!

29 year old here that only took physics for school science… wow I just learned so much! What a complex genius process, yet I’m amazed it all leads to such a simple pattern-matching exercise.
Thank you for making this public, and fantastic explanation!

Wow, I've always wanted someone to explain what I was looking at when they show DNA in the gel. Thank you for the simple explanation.

I enjoy this channel immensely!! I am hoping your organization continues to post your information on YouTube for all to be able to access and learn from. As I have no idea when and if I will be going to New York 🗽 any time soon, and even if I were and then were able to go to your organization I wouldn’t get as much out of your organization as I am able to with YouTube as a tool. The channel as a whole is extremely valuable to all people. ♥️

Fantastic presentation. Your lecture skills are nearly flawless, which your slides complemented nicely, especially the animation slides followed by the actual video of an electrophoresis run. Also, good teaching points from the imperfections in your students' experiment, such as the vertical line in the E3 gel sample (at 40:30) or switching S1 and S2 for the E4 and E5 runs. (Mayle: "Okay. So, no problem!") I'm glad you used their experiment rather than one without those issues. Thank you, and well done
