Originally coined "ergosomes" in 1963 they were further characterized by Jonathan Warner, Paul Knopf, and Alex Rich.〔 (Summary )〕 Polysomes can be directly visualized by electron microsopy because they form very high molecular weight particles.〔 Many ribosomes simultaneously read one mRNA progressing along the mRNA to synthesize the same protein. They may appear as linear polysomes or circular rosettes with microscopy but are mainly circular in vivo. This circularization is aided by the fact that mRNA is able to be twisted into a circular formation, creating a cycle of rapid ribosome recycling and utilization of ribosomes. The 5' 7-methylguanosine cap and 3' poly(A) tail present on eukaryotic mRNA aid in this process. Polyribosomes can be found in three forms: free, cytoskeletal bound, and membrane bound. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Polysome」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
