Students will use a Sickle Cell Anemia case study to learn about allele frequencies, genetics, and molecular biology.

This lesson plan requires students to analyze DNA restriction maps to determine the differences in the sequence for several primates and humans. They then use the information to create a cladogram.

YouTube video continues the discussion of molecular phylogenetics and reconstruction of the tree of life.

Learn how a standard lab technique, polymerase chain reaction, amplifies a single or several copies of a piece of DNA. [0:55]

A video discussing the molecular structure of DNA. Understand that DNA is made up of a phosphate, deoxyribose sugar, and one of the four nitrogen base. Video also explains how the nitrogen bases pair up to form the double helix...

This video tutorial gives a detailed description of the various molecular actors in the light-dependent reactions. [6:37]

Brief text summary of what students learn in the Dragon Genetics II lab along with links to download Student Handouts in PDF and Word formats, and Teacher Preparation Notes in PDF format. Students use paper models to learn transcription...

In this video, learn how fetal surgeons can help repair a birth defect of the spine known as Spina Bifida.

Learn about the gene as a stretch of DNA on a chromosome. Also find out about alleles as versions or sequence variants of a gene. [8:17]

Video lecture illustrates the complexity of signal transduction with a MAPK pathway and how transduction can actually occur. Also, looks at how mutations in the pathway are linked to cancer. [6:34]

Mr. Andersen explains the concepts of genetic recombination and gene mapping. [9:43]

(This activity is for a more advanced class such as honors or AP Biology.) The activity will look at one of the most important tools to the molecular biologist, PCR (Polymerase Chain Reaction). The young scholars will learn the science...

A video exploring the process of fertilization where two sets of chromosomes come together to form a zygote. Video defines haploid, diploid, zygote, and fertilization. [10:26]

Learn about what happens to the cell during interphase in this video. Video will review how the cell prepares for cell division including chromosome changes, centromeres, and many more. [8:27]

A video discussing the similarities and differences between the processes of mitosis and meiosis. Learn how mitosis results in two identical diploid cell while meiosis results in four haploid genetically different cells. [5:50]

A video explaining embryonic and somatic stem cells by overviewing early development of an embryo. Also discussed is the reasons why embryonic stem cell research can be controversially. [19:54]

In this video tutorial, you will learn how a zygote, the single cell produced by fertilization, divides by mitosis to produce all the tissues of the human body. [9:35]

Video tutorial provides an overview of DNA transcription, translation, and replication during mitosis and meiosis while also teaching about chromosomes, chromatids, and chromatin. [18:23]

Video lesson provides an overview of mitosis and what happens in its phases: prophase, metaphase, anaphase, and telophase. [12:11]

This video lesson explores how homologous chromosomes exchange fragments in prophase I. [12:15]

Video lecture explores the phases of Meiosis I: prophase 1, metaphase 1, anaphase 1, and telophase 1. It also investigates how homologous chromosomes separate into two sets. [9:44]

Video lesson presents an introduction to what cancer is and how it is the by-product of broken DNA replication. [12:35]

Video lecture provides a discussion on apoptosis (programed cell death) and how it is different from cell death by injury. Also, delves into its role in development and body maintenance. [10:47]

Learn about the structure of fructose in this video. See how its structure compares with glucose. [9:38]
