In the 1950s, the structure of DNA was discovered by using models and x-ray chromatography. Currently, science has used advanced technology to completely map out the genes in a human’s body. What would be the best advantage of using this information?

Mapping human genes helps scientists identify genes linked to inherited diseases and understand what is wrong with them. That information can support gene therapy, which aims to repair or replace defective genes. Removing bacteria from soil is unrelated to mapping human genes, and the information does not directly determine how many communicable diseases occur.
