Final answer:
Microbiologists and geneticists use genome mapping to find desired genes when studying and mapping the human genome. Genome mapping helps researchers study individual genes and identify disease-causing genes in human illnesses.
Step-by-step explanation:
Microbiologists and geneticists apply genome mapping to locate a desired gene when studying and mapping the human genome, the basis for all human life. Genome mapping is the process of finding the locations of genes on each chromosome. Genetic maps provide the big picture, listing genes and their locations on a chromosome, while physical maps provide more detailed information on the physical distance between genes. Having a complete map of the genome makes it easier for researchers to study individual genes and identify disease-causing genes related to illnesses like cancer, heart disease, and cystic fibrosis.
