In addition, regulatory sites on prokaryotic DNA are typically located ... quite far from transcription promoter sites. Also, eukaryotic gene expression is usually regulated by a combination ...

While slower, eukaryotic protein synthesis provides a higher degree of regulation than prokaryotic systems, allowing for ...

Sequence-specific transcription factors are considered the most important and diverse mechanisms of gene regulation in both prokaryotic and eukaryotic cells (Pulverer, 2005). In eukaryotes ...

Horizontal gene transfer (HGT) is the movement of genetic material from one organism to another. In this article, we will ...

“This is the most exciting and important paper on big questions about eukaryotic origins and the tree of life in years,” said evolutionary biologist Jeffrey Palmer of Indiana University, Bloomington, ...

As an independent investigator at the National Institutes of Health (NIH)—where she set up shop in 1976—Gottesman made major contributions in the field of prokaryotic gene regulation, uncovering key ...

plasmids are found in a few simple eukaryotic organisms. Prokaryotic cell DNA is a single molecule, found free in the cytoplasm; additional DNA is found on one or more rings called plasmids.
