In prokaryotes, the DNA (chromosome) is in contact with the cellular cytoplasm and is not in a housed membrane-bound nucleus. In eukaryotes, however, the DNA takes the form of compact chromosomes ...
Figure 1: Overview of the eukaryotic ubiquitin–proteasome system. Regulated proteolysis has profound implications for eukaryotic physiology, controlling numerous processes, including gene expression ...
Proceedings of the National Academy of Sciences of the United States of America, Vol. 107, No. 12 (March 23, 2010), pp. 5593-5598 (6 pages) Although membrane-bounded compartments are commonly ...
The Argonaute (Ago) enzyme complex plays a critical role in DNA and RNA target cleavage for a process known as RNA silencing in prokaryotic and eukaryotic cells, making them a target for future ...
System can be applied to enrich for mRNA in transcriptomes from pure and mixed microbial cultures. Washington University in St. Louis and the University of Washington became the first two institutions ...
A new version of a genome annotation system capable of analyzing more than 2,000 prokaryotic genomes per day has been revealed by scientists, helping researchers accelerate prokaryotic genomics-based ...
Taurine, an amino acid-like compound, acts as an osmostress protectant in many marine metazoans and algae and is released via various processes into the oceanic dissolved organic matter pool. Taurine ...
In the beginning, there was boredom. Following the emergence of cellular life on earth, some 3.5 billion years ago, simple cells lacking a nucleus and other detailed internal structure dominated the ...
Current hypotheses suggest that all life on Earth evolved from a common ancestor that diversified into the variety of organisms seen today. Scientists propose that the eukaryotic branch of this family ...
