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 ...

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 ...

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 ...

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 ...

DNA methylation refers to the process of adding a methyl group to specific regions of DNA. This process can bring about changes in the activity of DNA without changing the sequence of nucleotides.

Deep in hydrothermal vents beneath the Arctic Ocean, scientists have discovered an organism that sheds fresh light on the evolutionary link between simple and complex cellular life. The microbe and ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. A team of researchers has uncovered a new biological editing system ...

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 ...
