Genetic Engineering & DNA Plasmid

1. Genetic Engineering & DNA Plasmid

This lesson will discuss what a GMO is, and how DNA plasmids are used in genetic engineering. The lesson will include these important features of plasmids: a multiple cloning site, an origin of replication, and a selectable marker.

Restriction Enzymes: Function and Definition

2. Restriction Enzymes: Function and Definition

Restriction enzymes played a critical role in the advent of genetic engineering. In this lesson, you will learn what role restriction enzymes play in creating recombinant DNA.

How Ligase is Used to Engineer Recombinant DNA

3. How Ligase is Used to Engineer Recombinant DNA

DNA ligase makes recombinant DNA technology possible. In this lesson, you will learn how new versions of genes can be designed for experiments in novel host organisms using DNA ligase.

Agarose Gel Electrophoresis: Procedure & Analysis

4. Agarose Gel Electrophoresis: Procedure & Analysis

Gel electrophoresis is a biology lab technique used to analyze large molecules like DNA. The technique relies on moving charged molecules through a gelatin-like matrix using an electric field.

Ethidium Bromide, Loading Buffer & DNA Ladder: Visualizing DNA and Determining its Size

5. Ethidium Bromide, Loading Buffer & DNA Ladder: Visualizing DNA and Determining its Size

In this lesson, you will learn about the role that ethidium bromide, loading buffers, and DNA ladders play in visualizing DNA and determining the size of DNA fragments in agarose gel electrophoresis.

Bacterial Transformation: Definition, Steps & Analysis

6. Bacterial Transformation: Definition, Steps & Analysis

Bacteria can pick up genes or pieces of DNA from their environment in a process called transformation. In this lesson, we'll explore how this natural process can be exploited in the lab for genetic engineering of bacteria.

Polymerase Chain Reaction: Definition & Steps

7. Polymerase Chain Reaction: Definition & Steps

Have you ever wondered if you could make millions of copies of something in a matter of minutes. We're not discussing a copy machine, but rather a fascinating laboratory procedure called polymerase chain reaction. Learn all about it in this lesson!

DNA Cloning: Definition and Process

8. DNA Cloning: Definition and Process

DNA cloning is used for a variety of purposes, but how does it work? In this video lesson, you will learn about the process of cloning DNA, as well as see examples of how cloning is used in science, medicine, and consumer products.

Genomic DNA Analysis

9. Genomic DNA Analysis

Your genes are what make you who you are, but they also make you a human. Studying genes and genomes allows scientists to better understand not only our own species, but how we are related to other species in the world as well.

Practical Applications & Safety Concerns of DNA Technology

10. Practical Applications & Safety Concerns of DNA Technology

Our discovery of DNA was a big deal, but what technologies has it led to? And could they be dangerous? Learn about DNA technology, and then test your knowledge with a quiz.
