Final answer:
The study of genomes is important in identifying drug targets and developing more personalized medications based on an individual's genetic makeup.
Step-by-step explanation:
The study of genomes is important in identifying drug targets because genes function by directing the synthesis of specific proteins, and most pharmaceuticals work by altering the activities of these proteins. Understanding the human genome enables a better understanding of protein activity and facilitates the development of more specific drugs. For example, the gene responsible for cystic fibrosis was discovered through the examination of family histories, and it took many years to develop drugs to combat the disease.
Pharmacogenomics is a field that evaluates the effectiveness and safety of drugs based on an individual's genomic sequence. By studying changes in gene expression, we can gain insights into the transcription profile and potential toxic effects of drugs. Personal genome sequence information can also be used to prescribe medications that are most effective and least toxic based on an individual's genotype.
Overall, studying genomes helps in identifying drug targets and developing more personalized medications for individuals based on their genetic makeup.
