RPA shields inherited DNA lesions for post-mitotic DNA synthesis
Single-stranded DNA during DNA replication and repair in S/G2 needs protection by replication protein A (RPA). Here the authors reveal that RPA also shields inherited single-stranded DNA in G1, representing replication remnants from the previous cell ...

Biochemical analysis of human Dna2 [PDF]
Yeast Dna2 helicase/nuclease is essential for DNA replication and assists FEN1 nuclease in processing a subset of Okazaki fragments that have long single-stranded 5' flaps. It is also involved in the maintenance of telomeres.

Molecular Spiders in One Dimension [PDF]
Molecular spiders are synthetic bio-molecular systems which have "legs" made of short single-stranded segments of DNA. Spiders move on a surface covered with single-stranded DNA segments complementary to legs.

Cooperativity-Dependent Folding of Single-Stranded DNA
The folding of biological macromolecules is a fundamental process of which we lack a full comprehension. Mostly studied in proteins and RNA, single-stranded DNA (ssDNA) also folds, at physiological salt conditions, by forming nonspecific secondary ...

DNA Renaturation at the Water-Phenol Interface [PDF]
We study DNA adsorption and renaturation in a water-phenol two-phase system, with or without shaking. In very dilute solutions, single-stranded DNA is adsorbed at the interface in a salt-dependent manner.

Hypermutation in single-stranded DNA
Regions of genomic DNA can become single-stranded in the course of normal replication and transcription as well as during DNA repair. Abnormal repair and replication intermediates can contain large stretches of persistent single-stranded DNA, which is extremely vulnerable to DNA damaging agents and hypermutation.

Monomeric PcrA helicase processively unwinds plasmid lengths of DNA in the presence of the initiator protein RepD [PDF]
The helicase PcrA unwinds DNA during asymmetric replication of plasmids, acting with an initiator protein, in our case RepD. Detailed kinetics of PcrA activity were measured using bulk solution and a single-molecule imaging technique to investigate the ...

RNA Interference by Single- and Double-stranded siRNA With a DNA Extension Containing a 3′ Nuclease-resistant Mini-hairpin Structure [PDF]
Selective gene silencing by RNA interference (RNAi) involves double-stranded small interfering RNA (ds siRNA) composed of single-stranded (ss) guide and passenger RNAs.

Furan-PNA : a mildly inducible irreversible interstrand crosslinking system targeting single and double stranded DNA [PDF]
We here report on the design and synthesis of tailor-made furan-modified peptide nucleic acid (PNA) probes for covalent targeting of single stranded DNA through a crosslinking strategy.
