Even fairly deep sequencing of randomly selected cDNA clones fails to elucidate the structures of the 20–40% of genes in a typical eukaryotic genome that are expressed only at low levels or ...

Some four billion years ago, when cellular life emerged, a typical primordial microbe ... species (known collectively as eukaryotes), protein-coding genes are nestled in vast stretches of DNA ...

Genetic studies have made it clear that eukaryotic horizontal gene transfer can and does happen. Exactly how, though, remains speculative. Christie is a seasoned science journalist and cell and ...

The regulation of mRNA transcription plays a key role in relaying signals from the environment and during development into the gene expression program of a cell. During transcription initiation, a ...

Viruses acquire genes from eukaryotes — organisms whose cells store their DNA in a nucleus — and use them for their own function. Conversely, eukaryotes acquire genes from viruses to bring new ...

the proteins decouple from the multiplicative process of gene growth, and the average protein length stabilizes after the onset of the eukaryotic cell at about 500 amino acids in a clear threshold ...

A novel type of “jumping gene” may explain why the genomes of complex cells aren’t all equally stuffed with noncoding sequences. All animals, plants, fungi and protists — which collectively make up ...

the proteins decouple from the multiplicative process of gene growth, and the average protein length stabilizes after the onset of the eukaryotic cell at about 500 amino acids in a clear threshold ...

Eukaryotes and archaea have long been considered “sister groups” based on similarities in their genes and metabolic pathways. But it wasn’t clear whether eukaryotes and archaea shared a common ...
