New video posted: How long is the DNA in a human cell?

In this video, I calculate the length of the DNA in one human cell, and my answer may surprise you.

How long do you think? 0.2 mm, less? 2 mm, 2 cm, 2 m, 2 km? Watch the video to find out.

The video walks you through the math I used to calculate the length of DNA, and then I will reveal the length it would be if the cell were the size of a football.

New video posted: What is a cell?

This is an interesting question... what is a cell? What makes a cell a cell? Why do we have cells?

In a recent video post on YouTube, I addressed this question and explored some of the different cell types that can be found in the human body.

To find out more, watch the video and discover the remarkable range of sizes of cells in our bodies.
