The precise regulation of DNA methylation is essential for normal cognitive function. Indeed, when DNA methylation is altered as a result of developmental mutations or environmental risk factors, such as drug exposure and neural injury, mental impairment is a common side effect. The investigation ...
Deoxyribonucleic acid (DNA) is a molecule made up of two polynucleotide chains that coil around each other to form a double helix and carry genetic instructions for all known organisms and viruses' development, function, growth, and reproduction.Nucleic acids include DNA and ribonucleic acid (RNA)...

What is the basic function of a DNA molecule in a cell? What is the biochemical piece of DNA? What is DNA? What is the oldest DNA of any kind ever found? What are 3 parts of a DNA molecule? What is the full form of DNA? What is the strand of DNA that is not transcribed called?
DNA and enzymes are used as simple artificial analogues of the components of the AIS to create a system which responds to specific molecular stimuliin vitro. We show that this network of reactions can function in a manner which is superficially similar to the most basic responses of the ...
DNA methylation is a stable yet reversible epigenetic modification that regulates gene expression. New technologies have provided deep insights into the distribution and function of DNA methylation in humans, including the Human Roadmap Epigenome Project that defined genomewide methylation profiles across ...
We report the first observation of a spin-labeled ds 23-mer oligonucleotide by high-field electron spin resonance (ESR) and demonstrate that it interacts with AP endonuclease, the key enzyme in DNA abasic site repair. The spin labeled 23-mer with a U at position 12 of the upper strand is...
