Genomic DNA

 DNA is composed of units called nucleotides arranged into two long polynucleotide chains, resulting in a double helical structure. Nucleotides contain a phosphate group, a sugar group and a nitrogen base. There are four types of nitrogen bases namely adenine (A), thymine (T), guanine (G) and cytosine (C). The arrangement of these bases establishes the […]

Synthesis of Polyanionic C5-Modified 2′-Deoxyuridine and 2′-Deoxycytidine-5′-Triphosphates and Their Properties as Substrates for DNA Polymerases

Modified 2′-deoxyribonucleotide triphosphates (dNTPs) have widespread purposes in each current and rising biomolecular applied sciences. For such purposes it’s a necessary requirement that the modified dNTPs be substrates for DNA polymerases. To this point very few examples of C5-modified dNTPs bearing negatively charged performance have been described, although such nucleotides would possibly doubtlessly be worthwhile […]

Nanoparticle Superlattices through Template-Encoded DNA Dendrimers

The chemical interactions that result in the emergence of hierarchical buildings are sometimes extremely advanced and tough to program. Herein, the synthesis of a sequence of superlattices based mostly upon 30 totally different structurally reconfigurable DNA dendrimers is reported, every of which presents a well-defined variety of single-stranded oligonucleotides (i.e., sticky ends) on its floor. […]

EHMT2 (G9a) activation in mantle cell lymphoma and its associated DNA methylation and gene expression

Goal: The operate of euchromatic histone-lysine N-methyltransferase 2 (EHMT2) has been studied in a number of cancers; nonetheless, little is thought about its position in mantle cell lymphoma (MCL). Thus, this examine aimed to characterize the importance and performance of EHMT2 in MCL. Strategies: EHMT2 expression in MCL and reactive hyperplasia (RH) have been investigated by immunohistochemistry. […]

DNA Replication-Transcription Conflicts Do Not Significantly Contribute to Spontaneous Mutations Due to Replication Errors in Escherichia coli

Encounters between DNA replication and transcription may cause genomic disruption, notably when the 2 meet head-on. Whether or not these conflicts produce level mutations is debated. This paper presents detailed analyses of a big assortment of mutations generated throughout mutation accumulation experiments with mismatch restore (MMR)-defective Escherichia coli. With MMR absent, mutations are primarily on […]

Phylogenetic analysis of eight species of Anomopoda based on transcriptomic and mitochondrial DNA sequences

Phylogenetic analysis of eight species of Anomopoda based on transcriptomic and mitochondrial DNA sequences

Anomopoda is the widespread planktonic microcrustacean, which performs a vital function in aquatic ecosystem. There are few research in regards to the evolutionary relationships amongst varied Anomopoda basing on molecular information. Within the current examine, phylogenetic evaluation of eight Anomopoda was carried out. Firstly, the tradition system was developed to breed cladocerans. Through the use […]

Nanopore-Based Single-Molecule Investigation of DNA Sequences with Potential to Form i-Motif Structures

Nanopore-Based Single-Molecule Investigation of DNA Sequences with Potential to Form i-Motif Structures

i-Motifs are DNA secondary buildings current in cytosine-rich sequences. These buildings are fashioned in regulatory areas of the human genome and play key regulatory roles. The investigation of sequences able to forming i-motif buildings on the single-molecule stage is very essential. On this examine, we used α-hemolysin nanopores to systematically examine a sequence of DNA […]
