Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins. Scientists ...
RNA Polymerase (shown in blue) moves across a template strand of DNA (shown in purple) and transcribes it into RNA (shown in red). But DNA damage blocks the RNA polymerase, causing it to stall and ...
DNA transcription is a crucial process in the expression of genetic information, as it converts the information stored in DNA into messenger RNA, which can then be translated into proteins. Without ...
Researchers have discovered that in thale cresses histone H3 lysine-9 (H3K9) methylation, conventionally thought to be a mark of turning off gene transcription, can also turn on gene expression via ...
A new technology allows scientists to map, in single cells, the DNA binding sites of transcription factors and other regulatory proteins that control gene activity, according to a study led by ...
In eukaryotes, RNA polymerase II (Pol II) is the enzyme responsible for transcribing protein-coding genes (as well as non-coding RNAs). Pol II-mediated transcription is intricately regulated to ensure ...
A cell protein previously believed only to provide a scaffolding for DNA has also been shown to directly influence DNA transcription into RNA – the first step of the process by which an organism's ...
Biological transcription uses dynamic machinery modulated by transcription factors and auxiliary environmental cues to control multiple biological processes. Misregulation of the transcription ...
When the molecular machinery in our cells gets to work transcribing the genetic information encoded in DNA into messenger RNA (mRNA), it pauses shortly after starting. Known as promoter-proximal ...
Every living cell must interpret its genetic code - a sequence of chemical letters that governs countless cellular functions. A new study by researchers from the Center for Theoretical Biological ...
An international research team led by Forschungszentrum Jülich and the IPK Leibniz Institute has developed an artificial ...

The DNA from a single human cell would stretch about two meters if pulled into a line
Stretched into a single line, the DNA packed inside one human cell would reach roughly two meters, yet it folds into a nucleus just 5 to 10 micrometers wide. That compression ratio, on the order of ...
