Sentences with phrase «cellular factories»

In return, the bacteria, which don't die from the infections, provide an improved cellular factory to make new viruses.

They all use RNA molecules as messengers to transfer the information from DNA to cellular factories called ribosomes, which then build proteins, which in turn drive our metabolisms and form the structures of our cells.

In healthy cells constant growth can overwhelm cellular factories like the ER, leading to cell stress and death, but cancer cells manage to keep their factories running at high capacity to fuel non-stop growth.

Activation of a gene induces a cell to make an RNA copy of its code, edit unneeded segments out of that message, and splice together a final version of the message that provides cellular factories (ribosomes) with a template to make one specific protein.

It was a tall order: The first crystals of ribosomes — the cellular factories that translate nucleic acids into proteins — had been obtained in the early 1980s, but there were few labs with either the technical capacity or the desire to determine their structure.

Ribosomes, the cellular factories that manufacture proteins, contain both RNA and protein, but exactly how all of the different ribosomal components contribute to protein synthesis is still not clear.

The general architecture and workflow of these cellular factories has been understood for decades.

So, for example, a gene that promotes the production of insulin might be added to a microbe that scientists want to turn into a cellular factory of the diabetes medication.

«Signal in may send cancer's cellular factories into overdrive.»

Scientists at The Institute of Cancer Research, London, identified a molecular trigger responsible for ratcheting up activity of the endoplasmic reticulum (ER)-- the cellular factory that makes the building blocks cancer cells need to keep growing.

Based on previous work and their own results, Drummond and his colleagues speculate that a central purpose of protein aggregation during heat shock is to reshape the cellular factory, focusing protein synthesis on proteins needed during stress.

In the current paper, the shapes are made up of strut - reinforced tripods, which assemble themselves from individual DNA strands in a process called â $ œDNA origami.â $ Already, at 5 megadaltons, each tripod is more massive than the largest known single protein (titin, involved in muscle contraction) and more massive than a ribosome, one of the cellular factories in which proteins are made.

The cellular factory, the endoplasmic reticulum (ER), has a network of tubes that extend everywhere in the cell, including the synapse, de Camilli explains.
