The enzyme that makes RNA from a DNA template is altered to slow the production of ribosomal RNA (rRNA), the most abundant type of RNA within cells, when resources are scarce and the bacteria ...
Ribosomes are composed of two subunits, the small and large subunits, each containing specific rRNA molecules. The main types of rRNA include: Small Subunit rRNA: In prokaryotes, the small subunit ...
Scientists at McMaster University have identified a toxin used by bacteria to kill other bacteria through a never-before-seen mechanism. The toxin is the first found to directly target RNA molecules ...
A recent study into the interactions between aminoglycoside antibiotics and their target site in bacteria used computer simulations to elucidate this mechanism and thereby suggest drug modifications.
Proteins form the structural and functional backbone of the cell, and any perturbation in their synthesis can disrupt normal cellular functions. The DNA blueprint is carefully read, transcribed, and ...
The COVID-19 pandemic has brought global awareness to the dangers of emerging pathogens to human health and welfare. Common molecular tools used at scale, such as PCR, are best suited for detecting ...
Cryo-electron microscopy study allows researchers to visualize structural changes in an E. coli enzyme synthesizing ribosomal RNA that shift it between turbo- and slow-modes depending on the ...
