WebbForms of RNA polymerase I prepared from growing or encysted Acanthamoeba are equal in the ability to transcribe poly(dI:dC). Polymerase from cysts, whose rRNA genes are transcriptionally inactive, is unable to utilize the rDNA promoter in vitro, whereas the transcription initiation factor from cysts is fully able to bind the promoter and direct … WebbRibosomes occur singly (monosomes) or in cluster (polysomes). At the time of protein synthesis 6-8 ribosomes temporarily join with a mRNA to form a cluster called poly ribosome or polysome or ergosome.The number of ribosomes in a cell depends upon the active protein synthesis. In eukaryotic cells up to 10 million present.
