This clip looks at some of the beneficial and harmful aspects of transgenic plants.

Have you ever wondered how scientists get a sample of DNA from a plant, animal, or other organism? DNA is the genetic instructions for how an organism develops and functions. This video will show you how to extract enough DNA from...

Understanding Viruses - Viruses/Immunity Set - Part 1. This clip offers a simplified look at how viruses are structured and how they infect living host cells.

DNA (deoxyribonucleic acid) is a molecule that is often called the blueprint of life. Located in the nucleus, the DNA is a very long molecule with a helix winding structure like a twisted ladder. The rungs of the ladder are made of four...

Plant Reproduction Set: 5. This clip demonstrates two of the most common methods of genetic engineering in plants: biolistic transformation and gene splicing.

In this biology playlist, we've learned so much about DNA and living organisms! Well, so has mankind over the past century, and oh, what we have done with this knowledge! It's pretty incredible when you stop and think about it. Let's go...

We know that we are made of cells. But we start out as just one tiny little cell in the womb. How does that become enough cells to look like a baby? And how does that baby get enough cells to become an adult? The answer is mitosis! This...

Your cells have to divide when you're growing, to heal wounds, and to replace dead cells. But how do cells know when to divide and when not to divide? We can't have cells just growing willy-nilly! That's what cancer is, and that's bad....

Genetically modified organisms, or GMOs, have had their DNA artificially modified by humans, using modern genetic manipulation techniques. By changing the DNA, so changing the genome of an organism, means we can change its...

When we looked at some areas of biotechnology earlier in the series, we briefly touched on gene therapy, without saying much about what it is. Now we are ready to dive into this topic and see what it is all about. If a person has a...

Plant genome research is already revolutionizing the field of biology. Currently, scientists are unlocking the secrets of some of the most important plants in our lives, including corn, cotton and potatoes. Secrets of Plant Genomes:...

Concerns are growing over a new variant of the coronavirus blamed for a sharp rise in cases in the UK

We've been hearing about DNA since the third grade, and we all know that it's a double helix with little ladder rungs. But now we are ready to understand this molecule on a more fundamental level, which will enable to us to understand...
