GENOME
Did you know… Your Recipes in Every Cell display in Genome exhibition

The first draft of the human genome generated enough information to fill 200 telephone books (1000 pages each).

If a single atom were the size of a raisin, a molecule of DNA would be the size of a cat, and your body would be the size of North America.

Humans share about 99.9% of the same genes. In other words, we only differ from one another at the genetic level by one-tenth of 1%.

Humans have between 30,000 and 40,000 genes that pass along all the hereditary information from parent to child.

Except for sperm, egg and mature red blood cells, every single cell in the human body contains a complete set of genetic instructions.

We still don’t know the specific functions for over 50% of the genes in the human genome.

Over 30 genes have been identified as having a direct association with breast cancer, muscle disease, deafness, and blindness.


Genetic mutations occur almost twice as often in males as in females.

The same gentic mutation that causes sickle-cell anemia also confers resistance to malaria.

If the DNA in just one of your cells unwound, it would stretch to about six feet in length.
