A eukaryotic cell (left) has membrane-enclosed DNA, which forms a structure called the nucleus (located at center of the eukaryotic cell; note the purple DNA enclosed in the pink nucleus). A typical ...
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 ...
If our genes are so similar, what really makes a eukaryote different from a prokaryote, or a human from E. coli? The answer lies in the difference in gene expression and regulation used. Regulation of ...
What makes distinct species have different proteins? Is there a key that allows eukaryotic cells to produce proteins involved in multicellularity that are mostly absent in prokaryotes? What makes ...
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 ...

Janelia researchers have uncovered a novel way that two of the structures inside cells-the endoplasmic reticulum (ER) and lysosomes-coordinate the production of proteins, highlighting how interactions ...
Enzymes have clearly defined active sites to allow the substrate molecule to fit intricately. This is often coupled with an enzymatic conformational change prior to the occurrence of the catalysis ...
