Transcription and Translation: From DNA to Protein
Ok, so everyone knows that DNA is the genetic code, but what does that mean? How can some little molecule be a code that makes a single cell develop into a giraffe, or a monkey, or Tony Danza? Within this clip lie the answers, child!

Genetic Diseases
In this live-action program viewers will learn that a monogenic disorder is a genetic disease caused by small-scale genetic differences that cause the malfunction of a single gene and that many diseases result from such genetic...

Genetics: Linkage Problem #2: Map Distance, Coefficient of Coincidence, and Interference
In this video, we explore another linkage problem in genetics in which we determine the central gene, calculate map distances, and calculate coefficient of coincidence and interference. To see our first linkage problem, click the link...

What is Cancer?
Cancer is the ultimate expiration date for biological life. But what is it? How does it occur? Is there anything we can do about it? Let's take a brief look at this incredibly complex issue.

How to defeat malaria
Malaria still kills around 400,000 people a year. Efforts to eradicate the disease have stalled because of drug resistance—but pioneering gene-editing technology might offer a new solution

Beyond Mendelian Genetics Complex Patterns of Inheritance
We've already learned about Mendelian genetics, which taught us about dominant and recessive alleles and the laws that govern their inheritance. But things are not always so simple. There are situations that go beyond this basic...

What are Mendel and Genetic Crosses
Gregor Mendel that came up with the correct hypothesis for how inheritance of traits works. Mendel published his ideas in 1866, but it took until the 1900’s for his ideas to be recognised. Mendel studied the inheritance of different...

Inheritance of X-Linked Genes
We all know that DNA is the molecule of heredity, but we didn't always know that. It had to be demonstrated empirically. As it happens, some of the first evidence put forth had to do with genes found on the X-chromosome of fruit flies,...

Punnett Squares
Mendel proposed that you inherit a gene either from your mother, or from your father. But not a mixture of both. In this video we are going to look at monohybrid crosses using Punnett squares. A monohybrid cross is the study of the...

Protein Synthesis
Proteins are made of a long chain of amino acids, which has been coded for by DNA. The order of the bases of DNA determines which protein is made, by coding for a specific order of amino acids. This is protein synthesis, and in this...

Mutations
So, what causes mutations? Well, this is where science fiction meets science fact, sort of. In the backstory of many superheroes there will be a meeting with a radioactive substance - be it cosmic rays or radioactive waste. In real life,...
