Gene expression takes place in two stages: the transcription of DNA to RNA by an enzyme called RNA polymerase, followed by the translation of this RNA into proteins, whose behaviour affects the characteristics of each individual.
The mechanism by which 'polycomb' proteins critical for embyronic stem cell function and fate are targeted to DNA has been identified by UCL scientists.
(PhysOrg.com) -- A research team has made precise measurements of where and how RNA polymerase encounters obstacles while it reads nucleosomal DNA.
Using technology available through a local company, an Iowa State University researcher is working on a faster method to detect and genetically identify salmonella from contaminated foods.
Researchers have detected a link between alcohol consumption, cancer and aging that starts at the cellular level with telomere shortening.
(PhysOrg.com) -- In a world first, scientists in Australia announced on Wednesday they had extracted DNA from the fossilised eggshells of extinct birds, including iconic giants such as the moa and elephant bird.
Ovarian and breast cancer treatments being developed that mix a protein inhibitor and traditional anticancer drugs are showing signs of success, according to a new review for Faculty of 1000 Biology Reports.
(PhysOrg.com) -- Important molecular machines routinely crash into one another while plying their trades on DNA. New research shows that the enzymes that copy DNA before cell division, called replisomes, are the kings of ...
Scientists have shown that cells' DNA-reading machinery can skim through certain kinds of damaged DNA without skipping any letters in the genetic "text." The studies, performed in bacteria, suggest a new mechanism that can ...
(PhysOrg.com) -- A pair of University of Massachusetts Amherst chemists believe they have for the first time explained how the main players in transcription -- RNA polymerase, RNA (red in illustration) and the DNA template ...
