Plasma Membrane Anchoring and Gag:Gag Multimerization on Viral RNA Are Critical Properties of HIV-1 Gag Required To Mediate Efficient Genome Packaging

open access: yesmBio, 2021
Human immunodeficiency virus type 1 (HIV-1) Gag selects and packages the HIV RNA genome during virus assembly. However, HIV-1 RNA constitutes only a small fraction of the cellular RNA.

The mechanism of replication stalling and recovery within repetitive DNA

open access: yesNature Communications, 2022
DNA replication of repetitive sequences was recreated in a test tube using purified components. DNA alone was sufficient to induce stalling. Both stalling and recovery were dictated by the capacity of DNA to fold into unusual secondary structures.

A study on the correlation of nucleotide skews and the positioning of the origin of replication: different modes of replication in bacterial species [PDF]

open access: yes, 2005
Deviations from Chargaff's 2nd parity rule, according to which A∼T and G∼C in single stranded DNA, have been associated with replication as well as with transcription in prokaryotes. Based on observations regarding mainly the transcription-replication co-

Adaptation of HIV-1/HIV-2 Chimeras with Defects in Genome Packaging and Viral Replication

open access: yesmBio, 2022
Frequent recombination is a hallmark of retrovirus replication. In rare cases, recombination occurs between distantly related retroviruses, generating novel viruses that may significantly impact viral evolution and public health.

Proficient replication of the yeast genome by a viral DNA polymerase [PDF]

open access: yes, 2016
DNA replication in eukaryotic cells requires minimally three B-family DNA polymerases: Pol α, Pol δ, and Pol ϵ. Pol δ replicates and matures Okazaki fragments on the lagging strand of the replication fork.

Dicer prevents genome instability in response to replication stress [PDF]

open access: yes, 2019
Dicer, an endoribonuclease best-known for its role in microRNA biogenesis and RNA interference pathway, has been shown to play a role in the DNA damage response and repair of double-stranded DNA breaks (DSBs) in mammalian cells.

Reconstitution of a eukaryotic replisome reveals suppression mechanisms that define leading/lagging strand operation

open access: yeseLife, 2015
We have reconstituted a eukaryotic leading/lagging strand replisome comprising 31 distinct polypeptides. This study identifies a process unprecedented in bacterial replisomes.

The consequences of replicating in the wrong orientation: Bacterial chromosome duplication without an active replication origin [PDF]

open access: yes, 2015
Chromosome replication is regulated in all organisms at the assembly stage of the replication machinery at specific origins. In Escherichia coli the DnaA initiator protein regulates the assembly of replication forks at oriC.

Restriction of Influenza A Virus by SERINC5

open access: yesmBio, 2022
Serine incorporator 5 (Ser5), a transmembrane protein, has recently been identified as a host antiviral factor against human immunodeficiency virus (HIV)-1 and gammaretroviruses like murine leukemia viruses (MLVs). It is counteracted by HIV-1 Nef and MLV

Replication, Replication [PDF]

open access: yesPS: Political Science & Politics, 1995
Political science is a community enterprise; the community of empirical political scientists needs access to the body of data necessary to replicate existing studies to understand, evaluate, and especially build on this work. Unfortunately, the norms we have in place now do not encourage, or in some cases even permit, this aim.
