Confused about how chromosome numbers change before and after mitosis and meiosis? This Amoeba Sisters UPDATED video breaks down chromosome vs chromatid and shows how to count chromosomes and how they change in cell division, all...

Paul Andersen reviews the major concepts within the fifth unit of the new AP Biology framework. He starts with a description of both DNA and RNA. He explains how DNA is copied during the S phase of mitosis. He explains how...

Paul Andersen explains how cells duplicate through the process of cell division. Prokaryotic cells (like bacteria) duplicate through a process of binary fission. Eukaryotic cells (like you) duplicate body cells through mitosis and...

Explore chromosomes and karyotypes with the Amoeba Sisters! This video explains chromosome structure, how chromosomes are counted, why chromosomes are important, and how they can be arranged in a karyotype! This video also tackles a few...

In this video Paul Andersen explains the importance of mitosis and details the major steps in the cell cycle. He explains the importance of Interphase, Prophase, Prometaphase, Metaphase, Anaphase, Telophases, and Cytokinesis.

In this video, we will delve into the core of genetics as we break down the fundamentals of chromosomes, explaining what they are and how they impact our traits. Discover the intricate structure of chromosomes, from the double helix of...

Mitosis explores cell division by explaining the process and function of mitosis.

This nugget describes the structure, types and functions of chromosomes.

Mitosis for Anatomy and Physiology

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...

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...

Cellular Reproduction Set: 5. This clip reviews the series of events involved in the reproduction of the cell from interphase through mitosis to cytokinesis.

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....

Cellular Reproduction Set: 3. This clip describes the events of the five phases of mitosis: prophase, pro metaphase, metaphase, anaphase and telophase.

Meiosis Set: 2. This clip provides a detailed look at the phases of meiosis and the production of haploid sex cells.
