Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase ... not those "seen" by other sigma factors. This simple example illustrates how transcription can ...

RNA is synthesized from DNA by an enzyme known as RNA polymerase during a process called ... RNA is then translated into proteins by structures called ribosomes. There are three types of RNA ...

An RNA polymerase II molecule is about 15 nanometers across, or roughly 5,000 times smaller than the width of a human hair. This image was created by reconstructing X-ray diffraction crystallography ...

“It’s definitely a key advance in the field of understanding what RNA polymerase ribozymes can do, and it has pretty important implications for the RNA world theory,” he added. Study coauthors Gerald ...

Now, researchers used cryoelectron microscopy (cryo-EM) to elucidate the structure of the Nipah virus polymerase complex ... for both transcription and RNA replication and mutations that have ...

This pathway involves the conversion of simple precursor molecules ... beyond their role in DNA and RNA, as pyrimidines and their derivatives have significant applications in medicine and ...
