Nucleus of Bacteria

A unique feature of eukaryotic cells, which distinguishes them from bacteria, is the presence of a membrane-bound nucleus that contains the chromosomal DNA (illustrated; image credit). Surprisingly, a nucleus-like structure that forms during viral infection of bacteria is the site of viral DNA replication (link to paper). During infection of Pseudomonas bacteria…

Bacteria cells Have a Nucleus

Photo by: icholakov Hundreds of thousands of bacterial species exist on Earth. They can be found in very diverse environments ranging from cold to hot and alkaline to acid. They live in soil, in water, and on rocks. They exist deep in the earth, high on mountains, and in deep-sea vents. They grow on and in other bacteria, worms, insects, plants, animals, and…

Does Bacteria have a Protein Coat

EMBL discovery could yield evolutionary insights and new model organism This electron microscopy image shows Gemmata obscuriglobus . This and other PVC bacteria, the EMBL scientists discovered, have membrane-coat proteins associated with the membranes of subcellular compartments like the one shown in green, in which vesicles can be seen as dark green regions…

Microscopic Bacteria

The chaotic movements of bacteria could be tamed to create electricity, powering miniature future gadgets, such as medical devices or other nanoscale machines. A newly published paper from researchers at Oxford University explains how to turn a fluid soup of bacteria into a kind of miniature wind farm. The team dropped a minuscule array of 64 rotors into a microfluid…
