Bryophytes and the Life Cycle of Plants
We now understand that the ancestors of plants came from the ocean. But eventually, the first plants made their way out of the water and onto land. What did these plants look like? What functions were they capable of carrying out, and...

What Are Chromosomes
In the nucleus of each eukaryotic cell, the DNA is packaged together into chromosomes. Each chromosome is made up of DNA that is tightly coiled around proteins that give it the structure. Chromosomes usually occur in pairs, except for...

The Importance of Gregor Mendel's Work in Genetics
This video discusses the scientific work of Gregor Mendel. Through his experimentation, Mendel observed clear and predictable patterns of inheritance in the plant's characteristics, which he suggested were controlled by separate units...

Chromosomes, Mitosis, and the Cell Cycle: How New Cells are Made for Growth and Repair
The video explains the process of cell division and the importance of chromosomes and mitosis in the growth and repair of cells in animals and humans. It begins by introducing the concept of cells dividing in stages called the cell...

What Is Cystic Fibrosis
Cystic fibrosis is a genetic disease. It is caused by a defective gene on one of the chromosomes which has been inherited from the parents. The severity varies greatly from person to person, and largely depends on how much the lungs are...

Mechanisms of DNA Damage and Repair
Remember how the Ninja Turtles came to be? Yes you do. It was the ooze! A radioactive ooze that mutated their DNA in just the right way to give them the ability to walk upright, talk, and do ninjutsu. Now, I'm as a big a Turtle fan as...

Down's Syndrome
You might know, or have seen somebody with Down’s syndrome, but in this video, you are going to learn what it is and why it happens. Down’s syndrome is caused by a change in the DNA. You probably remember that any change in the structure...

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...

What Is The Difference Between Sex And Gender?
The difference between sex and gender is that sex is a biological concept based on biological characteristics such as difference in genitalia in male and female. Gender on the other hand, primarily deals with personal, societal and...

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...

Alteration of Chromosome Number and Structure
We've already learned about certain kinds of modification to the genome, namely in the way of mutations that can occur to specific base pairs, or frameshift mutations when base pairs are deleted or inserted. But there can also be...

Meiosis, Gametes, and the Human Life Cycle
We know that your body produces more cells through mitosis. But where did your very first cell come from? It can't have been mitosis, because mitosis needs a cell to start with. As it turns out, meiosis and subsequent fertilization are...

Mendelian Genetics and Punnett Squares
For all of human history, we've been aware of heredity. Children look like their parents. But why? When Gregor Mendel pioneered the field of genetics, he began to try to answer that question, and now that we know about chromosomes, all...
