In a recent study published in Nature Biotechnology, researchers developed a whole-genome sequencing (WGS) method that read four canonical deoxyribonucleic acid (DNA) bases, viz., adenine (A), ...

(Nanowerk Spotlight) Cytosine (C) modifications such as 5-methylcytosine (mC) and 5-hydroxymethylcytosine (hmC) are important epigenetic markers associated with gene expression and tumorigenesis.

Cytosine and adenine base editors (CBEs and ABEs) are promising new tools for achieving the precise genetic changes required for disease treatment and trait improvement. However, genome-wide and ...

Cytosine and adenosine base editors (CBEs and ABEs) are integral to molecular breeding, enable precise modification of single-nucleotide polymorphisms (SNPs) in plants, which are crucial for agronomic ...

DNA methylation is a fundamental epigenetic mechanism in which a methyl group is added onto a nucleotide, commonly cytosine. DNA methylation affects many biological processes, including gene ...

This is a preview. Log in through your library . Abstract The mechanism of DNA cytosine-5-methylation catalyzed by the bacterial M.Hhal enzyme has been considered as a stepwise nucleophilic addition ...

The DNA base cytosine has a lot of different outfits in its closet. Most famously, the base can slip on a methyl group at its fifth carbon, a change that lends cytosine the ability to silence genes.

Chemical structure of guanine, showing its double-ring purine structure and the functional groups involved in hydrogen bonding with cytosine. (Image: Public Domain) Guanine has the chemical formula ...

Although there are several methods for labeling and tracking RNA inside living cells, they lean heavily toward one side or another of a vexing tradeoff. At one extreme, there are labels that emit a ...
