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...

Synthetic Biology and Materials Science Part 1: Biological Manufacturing
We've discussed some aspects of biotechnology already, but we have yet to discuss the promising field of synthetic biology. We are now able to manipulate biological organisms in ways that have technological applications, and one of the...

Enzymes
Enzymes are really important proteins, that speed up the rates of reactions such as in photosynthesis, respiration and protein synthesis. The enzymes and substrates are always moving, and occasionally they collide at the right speed and...

Enzymes: Nature's Factory Workers
What are enzymes? Why they're nature's little factory workers. They chop up certain things! They build up others! Pretty amazing the kind of chemistry nature can do given enormous polypeptide chains with unfathomable variability and...

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...

Pharmaceutical Drugs: Inhibitors and the Nature of Disease
We live in a time where there is much skepticism towards modern medicine. This stems purely from ignorance, however, and there are those who capitalize on this to sell an unbelievable array of alternative medicines that, almost without...

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,...

Green Chemistry Principles - Catalysts
Learn the basics about the principle of green chemistry that concerns catalysis, as a part of environmental chemistry. A catalyst increases the rate of a chemical reaction. This means that desired products can be made more quickly, using...

Animation showing an example of the use of synthetic biology, to create bacteria engineered to detect the presence of parasites.
This bacterium contains both its own DNA (green helix) and an artificial part (blue) that codes for the production of surface proteins (circles) and other internal structures. These proteins are tailored to detect the presence of...
