The basic pattern of genomic DNA methylation is established at the time of embryo implantation through a wave of de novo methylation, but CpG islands are protected through a mechanism that ...

Animation of DNA’s knot-like i-motif structure the team mapped in 50,000 locations in the human genome, concentrated in key functional areas including regions that control gene activity Credit ...

Not all genes are active at all times. DNA methylation is one of several epigenetic mechanisms that cells use to control gene expression. This straightforward experiment demonstrated that it was ...

The human body is a remarkably complex machine, so it would make sense that it houses an abundance of DNA – the blueprints that help guide the body's growth and repair. But how much DNA do our ...

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 ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...
