Final answer:
Pharmacogenomics is the technology used to analyze genes and gene expression patterns affecting drug metabolism. It evaluates drug effectiveness and safety based on a person's genomic sequence and studies gene expression changes as an indicator of potential toxicity. Personal genome sequence information can guide prescription for the most effective and least toxic medications.
Step-by-step explanation:
Pharmacogenomics is the technology used to analyze variants of multiple genes or gene expression patterns that affect drug metabolism. Pharmacogenomics involves evaluating the effectiveness and safety of drugs based on information from an individual's genomic sequence. It studies changes in gene expression in the presence of a drug, which can be an early indicator of potential toxic effects. Personal genome sequence information can be used to prescribe medications that are most effective and least toxic based on the individual patient's genotype.
