Kinetics of renaturation of DNA.
The rate of renaturation of fully denatured DNA is kinetically a second-order reaction. The reaction rate increases as the temperature decreases below T,t, reaching a broad flat maximum from 15 to 30°C below T, and then decreases with a further decrease in temperature. Let N be the complexity of the DNA or the number of base-pairs iu non-repeating sequences per virus or cell for the given DNA, ...
متن کاملDNA renaturation at the water-phenol interface.
We study the renaturation of complementary single-stranded DNAs in a water-phenol two-phase system, with or without shaking. In very dilute solutions, each single-stranded DNA is strongly adsorbed at the interface at high salt concentrations. The adsorption of the single-stranded DNA is specific to phenol and relies on stacking and hydrogen bonding. We establish the interfacial nature of DNA re...
متن کاملCharacterization of denaturation and renaturation of DNA for DNA hybridization
OBJECTIVES The present study was designed to systematically characterize the denaturation and the renaturation of double stranded DNA (dsDNA), which is suitable for DNA hybridization. METHODS A series of physical and chemical denaturation methods were implemented on well-defined 86-bp dsDNA fragment. The degree of each denaturation was measured and the most suitable denaturation method was de...
متن کاملComplementary recognition in condensed DNA: accelerated DNA renaturation.
The functional consequences of DNA condensation are investigated. The recognition of complementary strands is profoundly modified by this critical phenomenon. (1) Condensation of denatured DNA greatly accelerates the kinetics of DNA renaturation. We propose a unifying explanation for the effects of several accelerating solvents studied here including polymers, di- and multivalent cations, as we...
متن کاملCasein kinase 2 inhibits the renaturation of complementary DNA strands mediated by p53 protein.
Considerable effort is currently being devoted to understand the functions of protein p53, a major regulator of cell proliferation. The protein p53 has been reported to catalyse the annealing of complementary DNA or RNA strands. We report that this activity is inhibited in the presence of the serine/threonine protein kinase CK2. It is shown that this inhibition can be explained by the occurrenc...
