Chromosome Research Aims and scope Submit manuscript

Abstract

Transcription by the three nuclear RNA polymerases is carried out in transcription factories. This conclusion has been drawn from estimates of the total number of nascent transcripts or active polymerase molecules and the number of transcription sites within a cell. Here we summarise the variety of methods used to determine these parameters, discuss their associated problems and outline future prospects.
