These bands were found to be sensitive to Exo m exonuclease,but not to A exonuclease, in consistance with the properties of other linear plasmids and chromosome in Streptomyces.
双向电泳及脉冲条件变换实验证明，这些DNA带都是线性分子。
They are generally divided into two classes: one is linear motor, including myosin, kinesin , dynesin, RNA polymerase and DNA helicase , the other is rotary motor, such as F 1 ATPase and the bacterial flagellar motor.
分子发动机是利用化学能 /化学势进行机械作功的生物大分子 ,包括线性分子发动机与旋转式分子发动机两大类 。
