Evolution settled on a genetic code that uses four letters to name 20 amino acids. Synthetic biologists adding new bases to DNA will be free to improve on nature — if they can.
The oldest law of genetics says that gametes combine randomly, but experiments hint that sometimes eggs select sperm actively for their genetic assets.
Puzzle solvers rediscovered a simple mathematical result of Mendelian genetics and weighed in on a Richard Dawkins metaphor.
Can you discover a simple mathematical result of Mendelian genetics that describes how genes interact with each other?
If DNA repair makes useful mutations more likely, it could accelerate cells’ adaptations to harsh environments.
The computational immunologist Purvesh Khatri embraces messy data as a way to capture the messiness of disease. As a result, he’s making elusive genomic discoveries.
The computational biologist John Novembre uses our genetic code to rewrite the history of humanity.
How to calculate when a gene’s rate of evolution will slow to a crawl.
How quickly will a gene’s rate of evolution slow to a crawl?
