They constantly untangle knots in the DNA strand and create new chemical bonds when a strand of DNA breaks somewhere in the ...

DNA is often seen as the blueprint of life—carrying the code to govern the development and traits of an organism—but “there are things beyond the DNA sequence,” says Xiaoqi Feng, a plant geneticist at ...

Many people that have written to us or I’ve talked to have used the test as inspiration to make really, really powerful life ...

Cells use many complex genetic repair backup systems to fix DNA damage and remain healthy throughout their lives.

DNA strand displacement circuits are inching closer to becoming cellular machines. Scientists are finding ways to make these programmable nanodevices stable and functional inside living cells. If ...

Upon binding, helicases melt the DNA, breaking the chemical bonds holding the double helix together. They then pull the two ...

Could it be that one of only three known markers directly targeting the DNA does not exist outside the realm of microbes? Now ...

A comprehensive review titled "From the Test Tube to the Cell: A Homecoming for DNA Computing Circuits?" published Mar. 4 in ...

Chemicals used as food preservatives, flavoring agents, dyes, pesticides, cosmetics, cleaners, and other industrial materials ...

These are chemical changes to DNA molecules that don't alter the genes within them, but rather affect which genes are ...

The researchers examined 850,000 sites of DNA methylation, where small chemical tags called methyl groups are added to DNA. This process can alter gene expression without changing the underlying ...

A medical breakthrough could result in the first treatment for rare but serious diseases in which genetic defects disrupt cellular energy production.
