Therefore, while bacteria accomplish transcription of all genes using a single kind of RNA polymerase, the use of different sigma factor subunits provides an extra level of control. Eukaryotic ...

Eukaryotic RNA polymerases use a number of essential cofactors (collectively called general transcription factors), and one of these, TFIID, recognizes the TATA box and ensures that the correct ...

The differences are summarized in Table 1, below. Table 1: Differences between prokaryotes and eukaryotes. In prokaryotic cells, transcription and translation are coupled, meaning translation begins ...

In addition to exporting materials out of the nucleus, the protein, called Exportin-1 (also called Xpo1 or Crm1), seems to play a role in promoting gene transcription, the process that creates RNA ...

A new method for mapping torsion provides insights into the ways that the genome responds to the torsion generated by RNA polymerase II.

In eukaryotic cells like human cells, transcription occurs in the nucleus, and the resulting mRNA is then transported to the cytoplasm for translation. Additionally, eukaryotic mRNA often ...
