Transmission electron micrograph of a polysome (polyribosome) purified from a rat liver homogenate by sucrose gradient centrifugation, and negatively stained with uranyl acetate. The linear arrangement of ribosomes bound to messenger RNA s clearly seen.由蔗糖梯度离心法从大鼠肝匀浆中纯化的多核糖体（多聚核糖体）的透射电子显微镜图像，经铀酰醋酸负染色处理，其中可见与信使RNA结合的核糖体的线性排列。
