RNA-directed DNA methylation involves co-transcriptional small-RNA-guided slicing of polymerase V transcripts in Arabidopsis. [PDF]
, 2018 Small RNAs regulate chromatin modifications such as DNA methylation and gene silencing across eukaryotic genomes. In plants, RNA-directed DNA methylation (RdDM) requires 24-nucleotide small interfering RNAs (siRNAs) that bind to ARGONAUTE 4 (AGO4) and ...

Bst polymerase — a humble relative of Taq polymerase
Computational and Structural Biotechnology Journal, 2023 DNA polymerases are a superfamily of enzymes synthesizing DNA using DNA as a template. They are essential for nucleic acid metabolism and for DNA replication and repair.

New link between the RNA polymerase II-CTD and replication stress
Molecular & Cellular Oncology, 2021 Conflicts between transcription and replication are a major source of replication stress. Our recent findings show that proper dephosphorylation of Serine 5 in the carboxy-terminal domain (CTD) of DNA-directed RNA polymerase II subunit RPB1 is needed to ...

DNA-directed DNA Polymerase Activity in Oncogenic RNA Viruses
Nature, 1970 Besides having RNA-dependent DNA polymerase activity, oncogenic RNA viruses possess a DNA-directed DNA polymerase which is distinguished from previously described enzymes of this type in preferring double-stranded DNA as template and yielding a principally double-stranded product.

Mechanisms of PARP inhibitor resistance in cancer and insights into the DNA damage response
Genome Medicine, 2018 Editorial summary Inhibitors of poly(ADP-ribose) polymerase (PARPi) have entered the clinic for the treatment of patients with cancers that lack homology-directed DNA repair, but drug resistance remains a clinical hurdle.

The ability to form homodimers is essential for RDM1 to function in RNA-directed DNA methylation. [PDF]
PLoS ONE, 2014 RDM1 (RNA-DIRECTED DNA METHYLATION1) is a small plant-specific protein required for RNA-directed DNA methylation (RdDM). RDM1 interacts with RNA polymerase II (Pol II), ARGONAUTE4 (AGO4), and the de novo DNA methyltransferase DOMAINS REARRANGED ...

Developments in the tools and methodologies of synthetic biology. [PDF]
, 2014 Synthetic biology is principally concerned with the rational design and engineering of biologically based parts, devices, or systems. However, biological systems are generally complex and unpredictable, and are therefore, intrinsically difficult to ...

Amplification of 4–9-kb Human Genomic DNA Flanking a Known Site Using a Panhandle PCR Variant
BioTechniques, 1997 We present a method for the in vitro amplification of >6.0 kb of DNA flanking a known site. This is accomplished by ligating an oligonucleotide to create an inverted repeat of a portion of the known sequence, followed by single-primer polymerase chain ...
