What is a gene? A human chromosome has thousands of genes Each gene is a recipe for a protein!
Genome Collection of genetic information within all genes contained in the DNA molecule(s) in a cell.
Fun Fact If the genome was a book, it would be the equivalent of 800 dictionaries. It would take a person typing 60 words per minute, eight hours a day, around 50 years to type the human genome.
