In fact, the mere presence of a nucleus is considered one of the defining features of a eukaryotic cell. This structure is so important because it is the site at which the cell's DNA is housed and ...

Life on Earth reached a decisive turning point about 2.6 billion years ago. An international team of researchers has just ...

The methylation of DNA in eukaryotes is often used to switch-off the signaling activity of the genes. DNA methylation has been shown to have an important role in several eukaryotic processes ...

Brandt Eichman and Walter Chazin, professors of biochemistry, have worked together to provide a better understanding of how exactly DNA replication is initiated in eukaryotes. Using Vanderbilt's ...

Scientists have uncovered a critical role for rapid DNA repair in maintaining genome stability. A new study reveals that ...

Although prokaryotic and eukaryotic cells have many differences, they share some common features, including the following: DNA: Genetic coding that determines all the characteristics of living things.

People have long wondered whether systems similar to the well-known bacterial CRISPR system exist in eukaryotes. The new study demonstrates that RNA-guided DNA-cutting mechanisms are present ...

The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus. The nucleus is ...

The study also shows that RNA-guided DNA-cutting mechanisms are present in both unicellular nucleus-lacking prokaryotes and multicellular nuclei endowed eukaryotes. “CRISPR-based systems are ...

Too much time has passed since eukaryotes first appeared on the evolutionary scene, and too much DNA has been scrambled between too many groups, for scientists to piece everything together. But that ...

In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive organelles, such as micro-compartments found in some bacteria, help organize cellular processes by concentrating ...
