Enzymatic-Like Properties of dsDNA and Its Comparison with ssDNA

A highly sensitive spectroscopic method using dichlorofluorescin (LDCF) was employed to study the rate of electron-transfer reaction in presence of dsDNA, ssDNA and some metal ions and imidazole derivative (N-trans cinnamoyl imidazole).Our results show that both kinds of DNA possess an enzyme-like catalytic activity in oxidative conversion of non fluorescent LDCF to fluorescent DCF. A biphasic ...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

extraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...

Simulations of single grafted polyelectrolyte chains: ssDNA and dsDNA

The structure of a single, grafted polyelectrolyte, DNA, is investigated by molecular dynamics simulations. The polyelectrolyte is treated as a bead–spring model with explicit charges using parametrizations of both flexible ~ssDNA! and stiff ~dsDNA! polyelectrolytes. In this single chain limit with no added salt, the flexible ssDNA is always highly extended. Counterion condensation on both mole...
