Mitosis & the Cell Cycle: How Cells Clone Themselves: Crash Course Biology #29
What’s the life of a cell like? In this episode of Crash Course Biology, we’ll follow a cell’s life cycle, from its beginning as a shiny new cell all the way to division via mitosis. We’ll learn how our cells control this process, and...

Eukaryotic Cell Cycle Regulation in 5 minutes
The cell cycle is a highly regulated process of eukaryotic cell division involving interphase (G1, S, G2 phases) for growth and DNA replication, followed by mitosis for chromosome segregation and cell division. Progression through the...

The Cell Cycle and its Regulation
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....

GCSE Biology - Cell cycles, Chromosomes & Mitosis #69
In order to survive and grow, organisms require a constant supply of new cells. In this video we explore how these cells are generated through the cell cycle, with a particular focus on mitosis. We will also look at the role chromosomes...

AP Biology Lab 3: Mitosis and Meiosis
Paul Andersen compares and contrasts mitosis and meiosis. He shows how you can count cells in various phases of mitosis to construct a cell cycle pie chart. He also explains how you can use the fungus Sordaria to calculate map units...

BIOLOGY - Environment - Nitrogen Cycle
Nitrogen makes up 78% of the air, however neither plants nor animals can take nitrogen directly from the air because nitrogen is so unreactive. The nitrogen cycles shows the movement of nitrogen through the environment. Nitrogen is...

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...

The Lifecycle of a Virus
This video is a lecture on the life cycle of viruses. The speaker starts by explaining that viruses are not true organisms because they are made up of different components and cannot replicate on their own. The video breaks down the...

Mitosis: How One Cell Becomes Two
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...
