DNA electrophoresis
This simulation assumes that the loading dye is 50bp and the marker is 50bp. (‘bp’ is a unit showing the number of base pairs of DNA.) Electrophoresis Electrophoresis is a chemical phenomenon in which an electric … more

Why are Cells Small?
Why are cells so small? Living cells are constantly exchanging substances with their surroundings. Cells have to absorb nutrients and get waste products out. Most cells, including our body, need to absorb oxygen to get energy. … more
Stopwatch for Pulse Measurement
Pulse When the heartbeats, blood flows through the blood vessels in a certain rhythm, causing the blood vessels to vibrate. This vibration is called the pulse. So, by measuring your pulse rate, you can find out … more
Asexual Reproduction and Sexual Reproduction
Asexual reproduction Some living things do not make reproductive cells. They make new offspring through cell division. This method of reproduction without male and female reproductive cells is called asexual reproduction. Sexual reproduction Many of the … more
