Gene expression is linked to RNA transcription, which cannot happen without RNA polymerase. However, this is where the similarities between prokaryote and eukaryote expression end. Central to the ...

The Pre-Initiation Complex (PIC), which consists of Mediator, TFIIA, TFIIB, TFIID, TFIIE, TFIIF, TFIIH, and RNA polymerase II (pol II), governs the expression of all protein-coding and most non-coding ...

In particular, the distribution of the promoter-associated small RNAs is similar to that of 'engaged' RNA polymerase ... Cap structures, which are added after the transcription of the first ...

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 ...

RNA is similar to DNA but contains uracil instead of thymine (T) and has a single-stranded structure ... or transcription, is the process by which RNA is produced using DNA as a template. This process ...

In DNA, two complementary strands of nucleotides pair up through hydrogen bonds between the bases (A with T and G with C) to form the iconic double helix structure ... RNA through the process of ...

This process of protein synthesis occurs in two stages - transcription and translation ... by an enzyme (helicase enzyme). The enzyme RNA polymerase attaches to the DNA in a non-coding region ...
