چکیده

A photoresponsive single-handed double helical supramolecule composed of complementary strands bearing azobenzene moieties underwent a reversible trans-cis-isomerization regulated by photoirradiation, resulting in a change in its molecular length.

Chiral tether-mediated stabilization and helix-sense control of complementary metallo-double helices.

A series of novel PtII-linked double helices were prepared by inter- or intrastrand ligand-exchange reactions of the complementary duplexes composed of chiral or achiral amidine dimer and achiral carboxylic acid dimer strands joined by trans-PtII-acetylide complexes with PPh3 ligands using chiral and achiral chelating diphosphines. The structure and stability of the PtII-linked double helices w...

Asynchronous synthesis of the complementary strands of the reovirus genome.

The mechanism of replication of the double-stranded RNA genome of reovirus has been analyzed by tracing the fate of the parental double-stranded RNA genome and by determining whether the complementary strands, which comprise the progeny double-stranded RNA, are synthesized simultaneously or sequentially. The results indicate that the parental double-stranded RNA is conserved as the original dup...

Evidence for a single-stranded adenovirus-associated virus genome: isolation and separation of complementary single strands.

Single-stranded adenovirus-associated virus type 2 deoxyribonucleic acid (AAV-2 DNA) has been isolated from the virion after enzymatic pretreatment of the particles by heating at 53 C for 1 hr in 0.015 m NaCl plus 0.0015 m sodium citrate in the presence of 1% sodium dodecyl sulfate. Double-stranded AAV-2 DNA present as a marker is not denatured by this treatment. AAV-2 single-stranded DNA is co...

A hetero-stranded double helix composed of m-diethynylbenzene-based complementary molecular strands stabilized by amidinium-carboxylate salt bridges.

A hetero-stranded double helix with a controlled helix sense was designed and synthesized from an optically active dimeric amidine and its complementary achiral dicarboxylic acid strand with conjugated m-diethynylbenzene backbones, being stabilized by the salt bridges.

A photochemical investigation of the dynamics of oligonucleotide hybridization.

The nucleic acid double strand helix is now known to have several structural forms that are themselves rather variable or changeable in response to environmental conditions such as ionic strength, temperature, and the presence of a wide variety of solutes in the solutions in which the solvent is almost always water. A common chemistry among all of these helical forms is the reaction that separa...
