Most cells in your body have a nucleus, what does it contain?
genetic material; the nucleus is arranged into chromosomes (23 pairs/46 single chromosomes)

What is a chromosome and a gene?
One very long molecule of DNA that's coiled up. A gene is a short length of a chromosome,=.
2 of 7
What is an allele?
Different versions of the same gene
3 of 7
Each gene is a code for making a certain protein. What are proteins and what does having different versions mean?
Proteins are the building blocks of cells. Having different versions of proteins means we end up with different characteristics.

They're part of things like skin, hair, blood and the cytoplasm in our cells, e.g collagen is a structural protein that is found in tendons, bones, cartilage.
