【简答题】
校长的领导和管理方式 某校长对工作非常负责，每天都在学校转悠，看看哪里有什么问题，希望及时纠正。按理说这位校长勤勤恳恳，教师们非常尊敬他，但有时候他的这种领导和管理方式让人感觉不到信任和无法接受。 有一次，全市要举行英语优质课比赛，该校长非常支持教师们，提供各种条件，最后全校选拔出一名出色的教师去参加比赛。校长亲自去昕这个老师的课、一一指点，不放过任何一个细节，某个句型应该怎样教，某个单词应该怎样帮助学生掌握，等等。可惜的是，这位校长并不是英语专业毕业，他的指导很难获得英语教师内心的认同，但是固于面子，英语老师觉得又应该听从他的一些建议，结果弄得这个教师无所适从，最后也没有取得理想的结果。 案例分析:该校长在领导和管理教职员工时存在什么问题?应该如何改进?

【多选题】Why do we think that the ribosome is a ribozyme?
A.
The rRNAs are folded into highly compact, precise three-dimensional structures that form the core of the ribosome. In contrast to the central positioning of the rRNAs, the ribosomal proteins are generally located on the surface, where they fill the gaps and crevices of the folded RN
B.
The main role of the ribosomal proteins seems to be to help fold and stabilize the RNA core, while permitting the changes in rRNA conformation that are necessary for this RNA to catalyze efficient protein synthesis.
C.
Not only are the three tRNA-binding sites (the A, P, and E sites) on the ribosome formed primarily by the rRNAs, but the catalytic site for peptide bond formation is formed by the 23S rRNA of the large subunit; the nearest ribosomal protein is located too far away to make contact with the incoming amino acid or with the growing polypeptide chain.
D.
The catalytic site in this RNA—a peptidyl transferase—is similar in many respects to that found in some protein enzymes: it is a highly structured pocket that precisely orients the two reactants—the elongating polypeptide and the amino acid carried by the incoming tRNA—thereby greatly increasing the likelihood of a productive reaction.
