For example, mycoplasmas do not have a cell wall ... 19 Bacteria possess specialized cellular structures that carry out essential functions, including energy production and protein transport, enabling ...

Unlike other cellular sub-structures (for example, the nucleus, mitochondria, and endoplasmic reticulum), the synapse does ...

All humans who have ever lived were once each an individual cell, which then divided countless times to produce a body made ...

“The structure of the brain at the cellular level appears to be near a phase transition,” said Northwestern’s Helen Ansell, the paper’s first author. “An everyday example of this is when ice melts ...

One cell ended up inside the other and evolved ... mitochondrion—and its potential to spawn new membrane structures. Take, for example, the compartment that Speijer thinks evolved early in ...

Now, a fourth example has been found ... colleagues have now shown that this bacterium has evolved into a new cellular structure, or organelle. It is the first known nitrogen-fixing organelle ...

These subcellular structures carry out specific jobs within the cell; for example, mitochondria power ...

For example, OPA1 helps maintain the architecture ... Aydin and his research group first separated OPA1 from cells and studied it in vitro to understand its atomic structure, which was no easy feat.

Not all DNA looks like the familiar twisted ladder. Sometimes, parts of our genetic code fold into unusual shapes. One such ...

Structure of a volume-regulated anion channel Although discovered only five years ago, important properties of these cellular valves have already been described. For example, it is known that ...
