Cell Cycle Regulators & Tumor Suppressor Genes | Proto-oncogenes & Oncogenes
In this video, we discuss the difference between proto-oncogene and oncogene AND the meaning of tumor suppressor genes. We also explore how dysfunction in any of these can lead to cancer.

Chromosome Structure and Organization
We've all seen pictures of chromosomes, and we know that they contain DNA. But how do we get from the double helix of DNA to the X-looking shape of a chromosome? Is it just DNA, or are there other things in there? How much DNA is in each...

DNA Replication: Copying the Molecule of Life
Your DNA needs to be in every cell in your body, so what happens when cells divide? How does each new cell retain all of the genetic information? The DNA is able to copy itself through a process called replication. Let's go through the...

DNA Replication
CREDITS Animation & Design: Bing Rijper Narration: Dale Bennett Script: Gemma Young It might be hard to believe, but at the very start of your life you were a single, microscopic cell called a zygote. Your body now contains millions of...

Understanding Meiosis: The Key to Genetic Diversity
This video explains the process of meiosis, which is essential for sexual reproduction. It details how cells undergo two rounds of division to produce four genetically diverse sex cells with only half the number of chromosomes. Through...

Viral Replication
Explain how viruses use the lytic and lysogenic cycles with an explanatory video. The resource also describes retroviruses and the virulence of bacteria.
TED-Ed
What Happens When Your DNA Is Damaged?
Did you know that your DNA can be damaged tens of thousands of times per day? Learn about the ways that damage to just one strand of your DNA can be fixed, or in extreme examples, result in genetic mutation such as cancer.

Longevity and Telomeres
Why do people age? Scholars explore the concept of telomeres and why they are so important in cells. They learn about the role of telomerase and why it is active in some cells—but not in others. The video also explains why some organisms...

Viruses and the Common Cold!
What do you really know about the common cold? Introduce learners to viruses, their components, and how they use host cells to replicate and infect more cells. Pupils identify the type of virus that causes the common cold and get...

Tri Nucleotide Repeat
Mutations often lead to genetic disorders. The tri-nucleotide repeat leads to an expansion of DNA thanks to errors in the process of DNA replication. Using the informative video, scholars identify genetic disorders related to this error...

Mismatch Repair
What does a cell do when DNA is not copied correctly? An informative video shows budding scientists an example of a mismatch mutation during DNA replication. Viewers learn that to prevent a mutation from occurring, cells have mechanisms...

DNA Replication (Advanced Detail)
Don't leave anything to the imagination! Use an animation to demonstrate the replication of DNA. The animation shows how the double helix separates and then begins copying nucleotides to create a copy.
