What are Mutations and what are the different types of Mutations?
A mutation is a random change in the DNA. Mutations can be neutral, which means it does not cause a change in a trait of the organism, or it could cause a beneficial or a harmful mutation. There are a few different types of mutations -...

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...

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...

Gene Linkage and Genetic Maps
We just learned about X-linked genes, but what about gene linkage in general? If two genes are on the same chromosome, we can say that they are linked. Are they always inherited together? Can the alleles rearrange in some way? Well don't...

Unraveling Sex Determination: From Chromosomes to Cats
This video explains how sex is determined in humans and animals, focusing on the role of chromosomes in determining gender. It explores the genetic basis of sex determination, highlighting the contribution of the father's sperm in...

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...

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...

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...

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,...

Understanding Meiosis: The Key to Genetic Diversity
This video explains the process of meiosis, which is essential for sexual reproduction. It details how cells undergo two rounds of division to produce four genetically diverse sex cells with only half the number of chromosomes. Through...
