Genome: Word that comes from combining “gene” and “chromosome.”
Each cell contains a copy of the genome.
Using sophisticated technologies, scientists are capable of peering into the cells of living beings.
For instance, with just a few drops of blood, they can read the information encoded in cells to unveil the hidden secrets of DNA.
Genes, which are tiny pieces of DNA, account for the specific traits of each individual, including eye colour, shape of the face or even the risk of developing certain genetic diseases, such as cystic fibrosis.
The full set of genes – ranging from 20,000 to 25,000 in each cell according to the latest estimates – is part of the human genome.
