Question

During the Human Genome Project, scientists created a gene map showing the relative location of each known gene on every human chromosome. This map led to the discovery that the human genome is made up of about how many genes?

Answer 1

Approximately 20,500 genes

Step-by-step explanation:

The Human Genome Project (HGP) was a 13-year international research effort aimed at determining the entire DNA sequence of the human genome. The HGP was launched in 1990 and completed in April 2013. This project helped to identify and physically map all the genes of the human genome. The sequence obtained from the HGP has been a very useful point of reference in order to identify and characterize mutations associated with genetic disorders. The HGP predicted approximately 20,500 genes (each of them produces an average of three proteins), which are distributed in the 23 pairs of chromosomes in the cells of our body.
