Scientists from the Helmholtz Institute for RNA-based Infection Research and collaborating institutions have developed a ...

Enzymes that cut DNA at specific sites are called endonucleases; these enzymes play many roles in genomic replication, fidelity, and defense. The initial discovery of restriction endonucleases in the ...

A research team led by scientists from the Helmholtz Institute for RNA-based Infection Research (HIRI) has introduced a new ...

With advances in genomics, scientists are discovering additional components of the DNA alphabet in animals. Do these unusual chemical modifications of DNA have a special meaning, or are they just ...

Histones are among the most abundant proteins in the body. They act as spools that help compact DNA so our enormous genomes will fit in the tight space of the nucleus. Each spool is made of eight ...

In humans and other eukaryotes, two principal epigenetic marks are known. A team has discovered a third, novel epigenetic mark -- one formerly known only in bacteria -- in bdelloid rotifers, small ...

Could it be that one of only three known markers directly targeting the DNA does not exist outside the realm of microbes? Now, researchers have demonstrated that this marker -- N4-methylcytosine (4mC) ...

Neuroscientists have uncovered a new mechanism for memory formation, and it involves changes in the structure of your DNA. If you were asked to picture a molecule of DNA, chances are you would ...
