Proceedings of the National Academy of Sciences of the United States of America, 1987 Comparison of plant mitochondrial (mt), chloroplast (cp) and nuclear (n) DNA sequences shows that the silent substitution rate in mtDNA is less than one-third that in cpDNA, which in turn evolves only half as fast as plant nDNA.

Chemistry of Abiotic Nucleotide Synthesis.
Chemical Reviews, 2020 The chemistry of abiotic nucleotide synthesis of RNA and DNA in the context of their prebiotic origins on early earth is a continuing challenge. How did (or how can) the nucleotides form and assemble from the small molecule inventories and under ...

Crystallographic observation of nonenzymatic RNA primer extension
eLife, 2018 The importance of genome replication has inspired detailed crystallographic studies of enzymatic DNA/RNA polymerization. In contrast, the mechanism of nonenzymatic polymerization is less well understood, despite its critical role in the origin of life ...

American Journal of Human Genetics, 2004 In this report, we describe a simple correction for multiple testing of single-nucleotide polymorphisms (SNPs) in linkage disequilibrium (LD) with each other, on the basis of the spectral decomposition (SpD) of matrices of pairwise LD between SNPs.

BLAST 2 Sequences, a new tool for comparing protein and nucleotide sequences.
FEMS Microbiology Letters, 1999 'BLAST 2 Sequences', a new BLAST-based tool for aligning two protein or nucleotide sequences, is described. While the standard BLAST program is widely used to search for homologous sequences in nucleotide and protein databases, one often needs to compare

Intracellular management of information: from DNA to proteins
tripleC: Communication, Capitalism & Critique, 2009 The living features of cells constitute an information flow from a central database, the nuclear DNA, to molecular effectors, proteins, which are synthesised in the cytoplasm.

Nucleotides in neuroregeneration and neuroprotection
Neuropharmacology, 2016 Brain injury generates the release of a multitude of factors including extracellular nucleotides, which exhibit bi-functional properties and contribute to both detrimental actions in the acute phase and also protective and reparative actions in the later recovery phase to allow neuroregeneration.
