The fidelity of replication of the three-base-pair set adenine/thymine, hypoxanthine/cytosine and 6-thiopurine/5-methyl-2-pyrimidinone with T7 DNA polymerase.
With the goal of constructing a genetic alphabet consisting of a set of three base pairs, the fidelity of replication of the three base pairs T(H) (5-methyl-2-pyrimidinone)/H(S) (6-thiopurine; thiohypoxanthine), C/H (hypoxanthine) and T/A was evaluated using T7 DNA polymerase, a polymerase with a strong 3'-->5' exonuclease activity. An evaluation of the suitability of a new base pair for replic...
متن کاملAT base pair anions versus (9-methyl-A)(1-methyl-T) base pair anions.
The anionic base pairs of adenine and thymine, (AT)(-), and 9-methyladenine and 1-methylthymine, (MAMT)(-), have been investigated both theoretically and experimentally in a complementary, synergistic study. Calculations on (AT)(-) found that it had undergone a barrier-free proton transfer (BFPT) similar to that seen in other dimer anion systems and that its structural configuration was neither...
متن کامل2-Methyl-6-(6-methyl-1H-benzimidazol-2-yl)phenol–2-methyl-6-(5-methyl-1H-benzimidazol-2-yl)phenol (3/1)
The title compound, 0.75C(15)H(14)N(2)O·0.25C(15)H(14)N(2)O, is a co-crystal of 2-methyl-6-(6-methyl-1H-benzimidazol-2-yl)phenol as the major component and 2-methyl-6-(5-methyl-1H-benz-imidazol-2-yl)phenol as the minor component. The refined site-occupancy ratio is 0.746 (4)/0.254 (4). The conformations of both components are identical except for that of the methyl substituent on the benzene ri...
متن کامل2-Methyl-6-[2-(trifluoromethyl)phenyliminomethyl]phenol
The title compound, C(15)H(12)F(3)NO, is a Schiff base which adopts the phenol-imine tautomeric form in the solid state. The dihedral angle between the aromatic rings is 38.79 (5)°. The mol-ecular structure is stabilized by an intra-molecular O-H⋯N hydrogen bond, which generates an S(6) ring. In addition, there is an intra-molecular short C-H⋯F contact.
متن کامل2-(6-Methyl-2-pyridyl)-1,1-diphenylethanol
The title compound, C(20)H(19)NO, was prepared from 2,6-lutidine and benzophenone. There are two symmetry-independent mol-ecules in the asymmetric unit. Each mol-ecule is involved in one intra-molecular O-H⋯N hydrogen bond. In the crystal structure, helical chains are formed along the b axis by weak π-π inter-actions between neighbouring mol-ecules [centroid-centroid distances between the pyrid...
