Precision Medicine Key Words You Need to Know

7 April 2021

Precision medicine uses a combination of genetic, lifestyle, and environment data to create tailored health strategies for individuals. DNA is built from just four chemical letters, forming a 3-billion-letter genome organised into 23 chromosome pairs. Genes within this genome instruct cells to produce 20,000 proteins that govern everything from eye colour to disease risk — forming the biological foundation that precision medicine draws on to personalise healthcare.

An infographic titled "Genes, Genomes and You" explains the basic difference between genes and genomes with visual elements.

The image explains genetic sequencing, comparing a healthy gene (GTCAGTC) with a mutant gene (GTCA-T-TC), and mentions whole genome sequencing.

An infographic explains next-generation sequencing and epigenetics, comparing DNA fragment reading and effects on twin’s cancer risk.
