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 ...
The mammalian elongation complex has remained a mystery – until researchers discovered how it controls its speed.
Scientists have pinpointed precise regions in the human genome where DNA is most likely to develop a mutation. At spots where RNA polymerase 'opens' your DNA to read and copy instructions – known as ...
The first 100 bases of many genes show excess mutations, revealing a major genomic weak spot that shapes disease risk and ...

Researchers are adding new evidence to the emerging concept that 'silent' or synonymous mutations may have crucial consequences. Their study showed how a synonymous mutation in one gene can ...
Researchers have discovered new regions of the human genome particularly vulnerable to mutations. These altered stretches of DNA can be passed down to future generations and are important for how we ...
Creative Biogene is always dedicated to providing researchers with the products and tools they deeply need to advance their research to new frontiers.
Polar bears are expected to become extinct but there are some signs their DNA is changing and they are adapting to new ...
