This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...
APOBEC-catalyzed cytosine-to-uracil deamination of single-stranded DNA (ssDNA) has beneficial functions in immunity and detrimental effects in cancer. APOBEC enzymes have intrinsic dinucleotide ...
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), ...
In many organisms, including plants, nucleic acid bases and derivatives such as caffeine are transported across the plasma membrane. Cytokinins, important hormones structurally related to adenine, are ...
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 ...
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 ...
