Histones vs Nonhistone Histones are small, very basic proteins rich in lysine and arginine. The histones are the basic building blocks of chromatin structure. The nucleoids of prokaryotic cells also have proteins associated with DNA, but these proteins are quite different from the histones and do not seem to form a comparable chromatin structure. Nonhistone chromosomal proteins-The histones are accompanied

1.填空题 (1)Visual Basic是一种面向的可视化程序设计语言,采取了的编程机制

Visual Basic的特点 可视化: Visual的英文含义既是可视化,在可视化环境下创 作前端界面也就如同摆放积木。 面向对象:面向对象编程是建立在类的基础上的,其通过类 的封装而使源程序更加便于维护。 部件编程:部件编程则使软件创建如同组装一辆汽车。 事件驱动:事件驱动则是指程序的执行路线是基于用户的操 作步骤来确定的
