For more than a century, Mendelian genetics has shaped how we think about inheritance: one gene, one trait. It is a model that still echoes through textbooks—and one that is increasingly reaching its ...

A genome is the complete set of genetic information contained within an organism. It includes all the DNA that makes up an organism's chromosomes, which are tightly coiled structures located in the ...

DNA is the chemical that codes for proteins which determine our physical traits. This molecule is a double coil connected by cross pieces (called bases). There are four bases that can vary in sequence ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

Researchers conduct large-scale studies with diverse groups to better understand the genetic factors that influence health and disease. The Million Veteran Program (MVP), for example, includes people ...

Gene editing is now reaching the mainstream, ushering in a new era of genetic manipulation. Traditionally, inserting or deleting entire genes, regulating their expression, and altering specific ...

Genetic testing identifies germline mutations, while genomic testing analyzes somatic mutations in tumors, influencing treatment options. Broader testing criteria are expanding access to genetic ...

Genetic testing can be a fearful, daunting, overwhelming, exciting, or joyful experience. In many cases, the emotions of people who pursue genetic testing can be described with more than just one of ...

When the Human Genome Project concluded 21 years ago, it opened the door for genetic testing and a promise for lifesaving screenings and personalized medicine. An innovation that serves as a key ...
