Our genes (aka. the genotype) determine our characteristics (aka. the phenotype). Evolution acts on changes in the phenotype, which occur when mutations change the underlying genotype. But what changes to the phenotype can ...

Not too long ago, biologists would induce mutations in an entire genome, isolate an organism that displayed a resulting disease or abnormality that they wanted to study, and then work backward to determine which gene was ...

(Phys.org)—A team of researchers from the University of California and the University of Tokyo has found a way to use the CRISPR gene editing technique that does not rely on a virus for delivery. In their paper published ...
An international team of researchers has found a way to diagnose disease and predict patient outcomes simply by measuring unbelievably small changes in interactions between molecules inside the body. The simple new technique ...

Genes do not exist in isolation. Like beads on a string, they sit next to each other on long DNA molecules called chromosomes. So far, little has been known about how the position of a gene on a chromosome affects its evolution. ...

Genes provide instructions to cells in the body telling them what to do and not do in order to function optimally. Small changes in genes, called mutations, can have major consequences. Similar to a glitch in a computer's ...
