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 ...

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 ...

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 ...

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 ...

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 ...

Researchers have revealed new details about the CRISPR-Cas5-HNH/Cascade complex, a variant of the type I-E CRISPR-Cas system, providing insights into its DNA recognition and cleavage mechanisms. The ...

The Royal Swedish Academy of Sciences has awarded the Nobel Prize in Chemistry for 2006 to Roger D. Kornberg of Stanford University "for his studies of the molecular basis of eukaryotic transcription.

A newly discovered promoter element "start" points to a shared regulatory syntax for controlling transcription initiation in bacteria, archaea, and eukaryotes. DNA is often described as the language ...

All complex life forms on Earth, including plants and animals, are made up of eukaryotic cells; they are more sophisticated than bacterial or archaeal cells, which are prokaryotic. Eukaryotes have ...

Proteins are essential biological molecules that perform a vast array of functions crucial for life, from catalyzing ...
