The prebiotic evolutionary advantage of transferring genetic information from RNA to DNA. [PDF]

, 2011
In the early 'RNA world' stage of life, RNA stored genetic information and catalyzed chemical reactions. However, the RNA world eventually gave rise to the DNA-RNA-protein world, and this transition included the 'genetic takeover' of information storage ...

RNA-directed DNA Methylation.

PLoS Genetics, 2020
RNA-directed DNA methylation (RdDM) is a biological process in which non-coding RNA molecules direct the addition of DNA methylation to specific DNA sequences.

African swine fever virus I267L acts as an important virulence factor by inhibiting RNA polymerase III-RIG-I-mediated innate immunity.

PLoS Pathogens, 2022
ASFV is a large DNA virus that is highly pathogenic in domestic pigs. How this virus is sensed by the innate immune system as well as why it is so virulent remains enigmatic.

Effect of UV Light on RNA-Directed DNA Polymerase Activity of Murine Oncornaviruses [PDF]

Journal of Virology, 1975
The UV inactivation of RNA-directed DNA polymerase activity of Rauscher leukemia virus was shown to be due to damage to the protein. The UV dose resulting in 37% survival of viral polymerase activity at 254 nm was 2.4 × 10 4 to 3.1 × 10 4 ergs/mm 2 .

Hachimoji DNA and RNA: A genetic system with eight building blocks [PDF]

, 2019
Reported here are DNA and RNA-like systems built from eight (hachi-) nucleotide letters (-moji) that form four orthogonal pairs. This synthetic genetic biopolymer meets the structural requirements needed to support Darwinism, including a polyelectrolyte ...

T4 DNA polymerase improves the efficiency of multiple site-directed mutagenesis

Biotechnology & Biotechnological Equipment, 2016
Site-directed mutagenesis (SDM) is a useful tool to study the functions of regulatory sequences of DNA and RNA, and the structures and functions of proteins. Numerous methods have been developed for either single or multiple SDM (MSDM).

Template-directed biopolymerization: tape-copying Turing machines

, 2012
DNA, RNA and proteins are among the most important macromolecules in a living cell. These molecules are polymerized by molecular machines. These natural nano-machines polymerize such macromolecules, adding one monomer at a time, using another linear ...

Structure and Function of a Mycobacterial NHEJ DNA Repair Polymerase [PDF]

, 2006
Non homologous end-joining (NHEJ)-mediated repair of DNA double-strand breaks in prokaryotes requires Ku and a specific multidomain DNA ligase (LigD).

Annotation of genomics data using bidirectional hidden Markov models unveils variations in Pol II transcription cycle

Molecular Systems Biology, 2014
DNA replication, transcription and repair involve the recruitment of protein complexes that change their composition as they progress along the genome in a directed or strand‐specific manner.

Extent of Transcription of Mouse Sarcoma-Leukemia Virus by RNA-Directed DNA Polymerase [PDF]

Proceedings of the National Academy of Sciences, 1974
The DNA product obtained from the endogenous RNA-directed DNA polymerase (deoxynucleosidetriphosphate:DNA deoxynucleotidyltransferase, EC 2.7.7.7) reaction of the Moloney sarcoma:leukemia viruses produced by the 78 A-1 cell line was analyzed and characterized.
