Cells are constantly subjected to DNA damage from a range of internal and environmental sources. It is estimated that cells ...

The other strand, known as the passenger strand ... the addition of single-carbon methyl groups to the transcribed DNA, leading to changes in gene organization that prevent further rounds of ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together ... More —like superglue— and creates a safe zone for other proteins to come repair the damage.

On their own, however, polymerases aren't good at staying on the DNA strand. They require CTF18-RFC in humans and Ctf18-RFC in yeast to thread a ring-shaped clamp onto the DNA leading strand ...

Most biochemistry labs that study DNA isolate it within a water-based solution that allows scientists to manipulate DNA without interacting with other molecules. They also tend to use heat to ...

"If this affects DNA strand separation, all protein interactions with DNA are also going to be affected," Marko said. "For example, the tendency for proteins to stick to specific sites on DNA and ...

The new study is based on the understanding that DNA is made up of two strands of molecular letters, or bases. Each strand is composed of four types of letters: adenine (A), thymine (T), guanine ...

First, they fabricated a universal single-strand DNA, as well as library of hundreds of short, single DNA strands called bricks. Each brick is composed of 24 nucleotides, including cytosine sites ...

Moderna’s mRNA COVID-19 vaccine does not alter human DNA or add a third strand to people’s DNA, as claimed in a video circulating on social media and viewed more than 400,000 times on Twitter.
