Genetics: Heredity, Traits & Chromosomes

1. Genetics: Heredity, Traits & Chromosomes

We view manipulation of genes in our crops and livestock as a recent development. Yet, man has been manipulating the genetic makeup of his food for thousands of years through cultivation and breeding. This lesson will begin to help you understand how genetics works.

Mendel's First Law: The Law of Segregation

2. Mendel's First Law: The Law of Segregation

Breaking up is a hard thing to do, but homologous chromosomes always go their separate way. What effect does chromosome segregation have on genetics? We look once more to Adrian's flying hamsters for answers.

Mendel's Second Law: The Law of Independent Assortment

3. Mendel's Second Law: The Law of Independent Assortment

Understanding how Mendel's law of independent assortment describes inheritance of genes is as easy as flipping a coin. Grab a few coins, cue up the video and see how.

Making Sense of the Genetic Code: Codon Recognition

4. Making Sense of the Genetic Code: Codon Recognition

Explore the genetic code and how it is translated into a polypeptide. We'll practice using the RNA codon chart and learn the basics of codon recognition.

How Does DNA Replicate?

5. How Does DNA Replicate?

In this lesson, we will learn why DNA replicates as well as how. We'll also learn about the rates of replication and how DNA proofreads itself. After watching the lesson, you can complete a short quiz to test your knowledge.

Protein Synthesis in the Cell and the Central Dogma

6. Protein Synthesis in the Cell and the Central Dogma

Learn the story of the central dogma and how it relates to protein synthesis. We'll use a simple analogy to explore the roles of transcription and translation in building protein from the DNA code. In this lesson, we'll also introduce the concept of a gene.

What is Genetic Engineering? - Definition and Examples

7. What is Genetic Engineering? - Definition and Examples

How do we make the insulin used by diabetic patients? In this lesson, you'll learn the basics of how genetic engineering can be used to transform a bacterial host cell into a genetically-modified organism that produces human insulin.
