DNA 'scrunching' occurs as RNA polymerase selects a position to begin synthesizing RNA Massive data analysis reveals basic processes in biology Date: March 3, 2016 Source: Children's Hospital of ...

RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription. As complex molecule composed of protein subunits, RNA ...

DNA encodes all genetic information, and is the blueprint from which all biological life is created. And that’s only in the short-term. In the long-term, DNA is a storage device, a biological flash ...

Once RNA polymerase and its related transcription factors are in place, the single-stranded DNA is exposed and ready for transcription. At this point, RNA polymerase begins moving down the DNA ...

Greedy accumulation-directed evolution generated multi-site combinatorial mutants of T7 RNA polymerase (T7 RNAP), breaking ...

In the latest shake-up for scientific dogma, research has demonstrated that eukaryotic cells can convert RNA sequences back into DNA, through a misunderstood, ‘error-prone’ polymerase. Historically, ...

This study reveals that RNA polymerase I uses a unique stalling mechanism at abasic DNA sites, distinct from RNA polymerase II. Pol I’s tendency to stall prevents the production of defective ...

Researchers led by FU Qiaomei from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences (CAS) reviewed the history of ancient DNA technological ...

Switching DNA and RNA on and off Date: August 21, 2018 Source: Springer Summary: DNA and RNA are naturally polarized molecules. Scientists believe that these molecules have an in-built polarity ...

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life.
