DNA, genes, genomes, biodata - discover more about all things DNA on the pages below.
All living things are made of cells. They are the basic building blocks of life. The human body is composed of trillions of cells, all with their own specialised function.
In the Cell
DNA is the long molecule that contains your unique genetic code. A bit like a recipe book, it holds the instructions your cells need to make all the proteins in your body.
Genes are small sections of DNA that code for a functional product, like a protein.
This hands-on activity allows you to extract the DNA from fruit using household items.
Mitosis is a process where a single cell divides into two identical daughter cells (cell division).
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information.
A genetic condition is usually a medical condition or illness, caused by a change in a person’s DNA sequence.
Health and Disease
Genetic testing looks for changes and variations in DNA that could put a person at higher risk of a genetic condition.
Infectious diseases are caused by microorganisms such as viruses, bacteria, fungi or parasites and can spread between individuals.

Living Things
For much of nature, natural selection and ‘survival of the fittest’ still play a dominant role; only the strongest can survive in the wild. As little as a few hundred years ago, the same was true for humans.
What makes a bird a bird or a mammal a mammal? Grouping creatures together can show what links different creatures together.
In this activity, learners discover how genes encode proteins, using a codon wheel and protein profiles.
