应用核酸分析技术对真菌进行分类，其理论基础及主要方法？
答案
参考答案：
酸分析技术大都以DNA同源性为基础，这就为那些具有表型特征相似的菌株在分子水平上给以界定。主要是核糖体脱氧核糖核酸（rDNA.序列测定、DNA分子杂交技术、线粒体DNA限制性片段长度多态性（RFLP）分析、随机扩增多态性分析（RAPD.技术等。

阅读下面短文，从方框中找出每段的中心句，与每一段落匹配起来。 Maybe you think of yourself as a good friend, but are you really? If you’re not sure, it’s time to think about what makes a true friend. 小题1:A good friend is busy but still manages to make time for your friends. He does not see friendships as a waste of time, or something to pay attention to only when he needs a favour. 小题2:Always be ready to listen to what the other person is telling you, even if sometimes it makes you uncomfortable. 小题3:Nothing ends a friendship faster than abandoning （抛弃） a friend in need. 小题4:When it seems like no one in your life will tell you the truth, your friend will have your back. 小题5:A true friend doesn’t gossip（说闲话） behind your back. When he doesn’t agree with you, it’s done in a respectful way that is meant for you both to come to an understanding.
