Web5 de fev. de 2011 · Description. This animation shows how a variety of proteins interact to regulate the transcription of eukaryotic DNA into RNA. During transcription, DNA is copied into RNA by an enzyme called RNA polymerase. As shown in the animation, this process involves many different proteins. Some of these proteins are general … WebIn Saccharomyces cerevisiae, gene expression in the late G 1 phase is activated by two transcription factors, SBF and MBF. SBF contains the Swi4 and Swi6 proteins and activates the transcription of G 1 cyclin genes, cell wall biosynthesis genes, and the HO gene. MBF is composed of Mbp1 and Swi6 and activates the transcription of genes …
