“…Sulyman (2020) remarks that the essence of leadership is not in the title or status attached to the position being occupied; it is about the values, impact and differences leaders are made with their positions. Hooper and Potter (2001) explicitly encapsulate the values of leadership by noting that leadership is about winning hearts and minds through effective persuasive leadership, using relationship and rapport skills, and also seeing the situation from other people's viewpoints.…”

The 21st century is distinguished for its new innovations and dependency on technology in all parts of libraries, while managers and leaders are two inseparable components of every developing library. This paper contest on who best fits the helms of affairs of libraries in the 21st century between managers and leaders. It explains that managers are always designed around current realities by serving as instruments of planning, controlling and measuring, while leaders are adaptive, flexible, responsive and adopt evolutionary approaches to drive changes. Some leadership patterns, such as purposeful leadership, visionary, transformational, transactional, autocratic, distributed, laissez-faire and servant are suggested as for librarians to adopt to position libraries for reckoning. It concludes that library managers need to elevate their games to become leaders because libraries will be limited and stagnated if management is prioritized over leadership. One of the recommendations of this paper is that library schools and other library-related institutions should be teaching leadership training to students.

“…Unknown test is very famous and so known, a lecturer put certain sugars in number of test tubes while students should know them by examine them by using above famous tests. In another words, certain molecules characterizing by famous certain experimental tests [1,4] . This situation is right for Hinsberg, Diazonium too but they are famous in organic chemistry laboratories especially in individuation classes of fourth stage in chemistry department.…”

There are specific chemical experimental tests using so widely over the world for characterizing different molecules. In this study, two classes of these tests has used for identifying two moieties: amine (as secondary amine) and pentose sugar (as deoxy ribose). Thirty DNA samples were hydrolyzed by concentrated hydrochloric acid to make pH of the medium = 0.3-0.8, then they were tested by above known laboratory tests; Hinsberg, Diazonium, Molisch, Benedict, Barfoed, Bial, Unsaturated test by copper acetate tests. These tests are so known in them roles showing amine moieties (primary, secondary or tertiary) and sugar molecules with its different classes. DNA samples have primary, secondary and tertiary amine and they have pentoses as deoxy ribose that means they have monosaccharide, aldopentose moieties. Therefore, above tests are specific for these molecules but results of this research show different situation that above tests gave negative results with DNA samples which indicates that DNA samples do not have secondary amine or pentose sugar in them molecules. In addition, FT. IR. Results show same indication as same as this study results. About five years (2014)(2015)(2016)(2017)(2018)(2019) are duration of this study.
