The genetic information stored in DNA is a living archive of instructions that cells use to accomplish the functions of life. Inside each cell, catalysts seek out the appropriate information from ...

“Until now, each of the 1 [million] to 10 million ribosomes within a cell has been thought to be identical and interchangeable,” study coauthor Maria Barna, a developmental biology and genetics ...

Cells change their ribosomes when they receive a danger signal ... the surface of a cell gives away a lot about what is happening on the inside. "Cells coat themselves with little chunks of ...

"A starved cell will eventually start digesting itself, so the ribosomes might be coating the mitochondria to protect them. They might also attach to trigger a signaling cascade inside the ...

Mitochondria are theroundish structures and are the energy factories within the cell. Rough endoplasmic reticulum is so-called because it has ribosomes attached to its outer surface. Smooth ...

“But what we found is that the chemical modification of the ribosome that is guided by the snoRNA actually had nothing to do with senescence,” Mendell said; the amount of protein synthesis in the cell ...
