The topic of this video module is genetic basis for variation among humans. The main learning objective is that students will learn the genetic mechanisms that cause variation among humans (parents and children, brothers and sisters) and...

Introduction to how groups of organisms evolve and how natural selection can lead to evolution. [17:39]

A detailed introduction to dioxyribonucleic acid, otherwise known as DNA. [28:05]

An introduction to heredity. Understand important terms in genetics like dominant and recessive traits, and heterozygous and homozygous genotypes. [17:27]

Understand how variation can be introduced into a species. [19:52]

A video investigating the hunt for the gene that causes autism. Learn how a parents crusade to help their child led to scientist finding a stretch of similar genes that may help solve the mystery about autism. [12:51]

Transcription Factors help influence which genes are used in which cell. Understanding how these dynamic proteins physically interact with DNA allows us to better understand and model their binding to DNA and their regulation of gene...

Matt Scott investigates how genes gave rise to new body plans in this video. His model is the fruit fly and the genes that control how the body is built. Geneticists, like Scott, often look at mutations to find their answers. Scott shows...

Sometimes trailblazers of science aren't famous like Darwin or Pasteur. Sometimes they're humble Abbots, just growing peas in the back of their Abbey. This is the story of Gregor Mendel and how his work was done, lost, then found again....

This lesson will examine the structure of DNA as being in the form of a double helix composed of nucleotides. It is 2 of 4 in the series titled "DNA:Structure- The Double Helix."
