Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase. However, this is where the similarities between prokaryote and eukaryote expression end. Central to the ...

Eukaryotic cells, however, tend to have more potential opportunities for gene regulation: for example, it’s also common for eukaryotes to have gene regulation that is post-transcription but before ...

Also, as the prokaryotic cell lacks a clearly defined nucleus and both transcription and translation takes place in the cytoplasm, there is no need to transport the mRNA to the cytoplasm after ...

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 ...

All modern organisms fall into two classes, eukaryotes and prokaryotes. Eukaryotes (from the Greek meaning “true kernel”) have a cell nucleus that harbours most of the cell’s genetic information and ...

Prokaryotic cells, which include all bacteria and archaea, are ancient, and relatively simple compared to eukaryotic cells, which are found in fungi, plants, and animals. Scientists have long sought ...

Yeast is a single cell eukaryotic organism, that incites in this Irish scientist an intense memory of the smell of brewing Guinness, wafting down the River Liffey on a drizzly Dublin day as I sit at ...

A newly discovered promoter element "start" points to a shared regulatory syntax for controlling transcription initiation in bacteria, archaea, and eukaryotes. Subscribe to our newsletter for the ...

Modern eukaryotic cells have proteins that enable chromosome segregation during cell division, new discoveries shed light on their origin in simpler prokaryotic organisms. Modern nucleated (eukaryotic ...
