The replication of DNA in Escherichia coli [PDF]

open access: green, 1958
Studies of bacterial transformation and bacteriaphage infection (1-5) strongly indicate that deoxyribonucleic acid (DNA) can carry and transmit hereditary information and can direct its own replication.

Testing Quantum Dynamics in Genetic Information Processing [PDF]

open access: yesJournal of Genetics 80 (2001) 39-43, 2001
Does quantum dynamics play a role in DNA replication? What type of tests would reveal that? Some statistical checks that distinguish classical and quantum dynamics in DNA replication are proposed.

Acceleration of DNA Replication of Klenow Fragment by Small Resisting Force [PDF]

open access: yesChin. Phys. Lett. 2021, 38 (11): 118701, 2021
DNA polymerases are an essential class of enzymes or molecular motors that catalyze processive DNA syntheses during DNA replications. A critical issue for DNA polymerases is their molecular mechanism of processive DNA replication. We have previously proposed a model for chemomechanical coupling of DNA polymerases, based on which the predicted results ...

MTBP phosphorylation controls DNA replication origin firing

open access: yesScientific Reports, 2021
Faithful genome duplication requires regulation of origin firing to determine loci, timing and efficiency of replisome generation. Established kinase targets for eukaryotic origin firing regulation are the Mcm2-7 helicase, Sld3/Treslin/TICRR and Sld2 ...

The structural basis of Cdc7-Dbf4 kinase dependent targeting and phosphorylation of the MCM2-7 double hexamer

open access: yesNature Communications, 2022
Here the authors describe multiple structures of the replicative helicase MCM2-7 in complex with Dbf4-dependent kinase (DDK). These structures reveal why the kinase specifically recognizes the MCM2-7 double-hexamer over the single-hexamer and explain how

The Contribution of Lysosomes to DNA Replication

open access: yesCells, 2021
Lysosomes, acidic, membrane-bound organelles, are not only the core of the cellular recycling machinery, but they also serve as signaling hubs regulating various metabolic pathways. Lysosomes maintain energy homeostasis and provide pivotal substrates for

Cryo-EM structures reveal that RFC recognizes both the 3′- and 5′-DNA ends to load PCNA onto gaps for DNA repair

open access: yeseLife, 2022
RFC uses ATP to assemble PCNA onto primed sites for replicative DNA polymerases δ and ε. The RFC pentamer forms a central chamber that binds 3′ ss/ds DNA junctions to load PCNA onto DNA during replication.

Cohesin causes replicative DNA damage by trapping DNA topological stress [PDF]

open access: yes, 2020
DNA topological stress inhibits DNA replication fork (RF) progression and contributes to DNA replication stress. In Saccharomyces cerevisiae, we demonstrate that centromeric DNA and the rDNA array are especially vulnerable to DNA topological stress ...

Single Cell Analysis of Human RAD18-Dependent DNA Post-Replication Repair by Alkaline Bromodeoxyuridine Comet Assay [PDF]

open access: yes, 2013
Damage to DNA can block replication progression resulting in gaps in the newly synthesized DNA. Cells utilize a number of post-replication repair (PRR) mechanisms such as the RAD18 controlled translesion synthesis or template switching to overcome the ...
