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 ...

In eukaryotic cells like human cells, transcription occurs in the nucleus, and the resulting mRNA is then transported to the ...

Transcription factors, which regulate transcription ... an organism he says is "an excellent model for eukaryotic cells" because it has many features in its nucleus that are present universally across ...
