What is DNA?

1. What is DNA?

In this lesson, we will learn what DNA is, what its characteristics and functions are, even where it is located and what information it contains. We'll also learn how the double helix is created. Find out more.

Differences Between RNA and DNA & Types of RNA (mRNA, tRNA & rRNA)

2. Differences Between RNA and DNA & Types of RNA (mRNA, tRNA & rRNA)

In this lesson, you'll explore RNA structure and learn the central dogma of molecular biology. Along the way, you'll meet the three types of RNA and see how the cell uses them most effectively.

DNA Testing in Forensic Science

3. DNA Testing in Forensic Science

DNA testing has revolutionized the field of forensic science. After defining and briefly discussing the uses for DNA testing, this lesson will review DNA testing procedures that are used in forensic investigations.

Nucleotide: Structure, Bonding & Mutations

4. Nucleotide: Structure, Bonding & Mutations

Nucleotides are the building blocks of DNA and RNA. In this lesson, you will learn about the different types of nucleotides, their structure, and how the change in a single nucleotide can affect the survival of an organism.

Complementary Base Pairing: Definition & Explanation

5. Complementary Base Pairing: Definition & Explanation

Explore the composition and structure of DNA molecules. Learn how DNA molecules are composed of four different types of nucleotides that pair with each other in a very specific, complementary manner.

Destructive & Non-Destructive Testing: Definition, Function & Examples

6. Destructive & Non-Destructive Testing: Definition, Function & Examples

In this lesson, you'll learn about why destructive tests are typically not desired and how non-destructive tests can be used instead. Then after learning this you can test your knowledge with a quiz!

PCR: Reagents Used in Polymerase Chain Reaction

7. PCR: Reagents Used in Polymerase Chain Reaction

Polymerase chain reaction (PCR) is a biotechnology technique that is used to amplify pieces of DNA. In this lesson, you will learn about five ingredients necessary to perform PCR: template DNA, nucleotides, primers, buffer and Taq polymerase.

What is Agarose Gel Electrophoresis?

8. What is Agarose Gel Electrophoresis?

Agarose gel electrophoresis plays a key role in genetic engineering experiments. In this lesson, you'll learn what agarose is and how electrophoresis works. You'll also discover the use of agarose in this procedure.

Agarose Gel Electrophoresis: Equipment & Procedure

9. Agarose Gel Electrophoresis: Equipment & Procedure

This lesson will review the concepts and mechanisms of agarose gel electrophoresis. It will also summarize the equipment needed to perform the procedure for DNA analysis.

DNA Sequencing: Definition, Methods & Applications

10. DNA Sequencing: Definition, Methods & Applications

DNA sequencing allows scientists to know the exact message coded in DNA. In this lesson, we'll talk about how DNA replication is the basis for sequencing, how scientists do DNA replication in the lab, and important uses for it in research and everyday life.
