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 ...

DNA has tremendous potential as a data storage medium, but the process of synthesizing DNA from scratch is time-consuming. It has to be done one nucleotide at a time in a specific sequence. New ...

The Human Genome Project changed everything. A map of the entire human sequence of DNA was the starting point for an enormous number of discoveries, from disease genes to how humans evolved. But DNA ...

Genome editing is a powerful biotechnology tool that allows scientists to make precise changes to an organism's DNA. It involves the use of specialized enzymes, known as engineered nucleases or ...

CpG density and epigenetic modification state modulate DNA mechanics, altering its intrinsic compatibility with nucleosome formation.

This Brush Up is sponsored by Cayman Chemical. Learn more about chemical inhibitors of histone modification. Histone modification affects how tightly DNA wraps around histone proteins, yielding ...

UCLA researchers analyzed a certain type of DNA marker across hundreds of mammal species and found associations with traits such as lifespan, weight and age. The study, published in August, examined ...

Long non-coding RNAs (lncRNAs) are RNA transcripts longer than 200 nucleotides that do not code for proteins. Once considered mere transcriptional noise, lncRNAs are now known to play vital roles in ...

DNA can also be demethylated, either through passive or active processes. Passive DNA demethylation occurs when the methylation pattern is not replenished during DNA replication and gradually ...
