Genes undergo extensive editing through a process called alternative splicing, which greatly increases the size of the functional genome—the working portion of our DNA that helps make each person ...

Although heart cells and skin cells contain identical instructions for creating proteins encoded in their DNA, they're able to fill such disparate niches because molecular machinery can cut out and ...

Gene mutations have consequences both good and bad—from resistance to conditions like diabetes to susceptibility to certain cancers. In order to study these mutations, scientists need to introduce ...

The opportunistic pathogen Candida albicans grows in two forms: yeast and filament. The latter state contributes to the severity of infections, and elevated temperature promotes this morphological ...

Cell function is determined by how DNA is expressed into proteins. That process includes two main steps—transcription, when messenger RNA (mRNA) makes copies of active genes; and translation, when ...

Human genes that encode proteins often contain non-coding segments known as introns. Removing introns is crucial for the proper expression of genetic information. Understanding how our cells ...

Genes are not passed on exclusively from parents to their offspring. Some are mobile and can also jump to other species, as ...
