mRNA Processing: The 5'-7-methylguanosine Cap

Let’s fly to Eukarytopia, the home of the eukaryotes! You can learn all about plants in the Garden of Babylon! This lesson will begin our series on eukaryotic cells. We’ll look at the structure of plant cells, focusing on components that...

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...

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...

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...

Glycolysis and Gluconeogenesis Regulation

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,...

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...

Maybe you’re doing dry January — abstaining from alcohol for the first month of the year. A new report from the United States Surgeon General might motivate you to keep that going. It lists alcohol as a leading preventable cause of...

L-glutamine (Gln, Q)

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...
