These cells and others in the body are exact copies of their parent cells -- they formed when their parent cells divided ... of DNA. We've now zoomed in enough to see portions of the DNA strand.

Fortunately, the models yielded different predictions about the distribution of old versus new DNA in newly divided cells ... a hybrid that consisted of one strand of old DNA bound to one strand ...

For the first time, scientists have captured the exact moment DNA begins to unravel, shedding light on a fundamental chemical process that enables DNA to serve as the blueprint for life.

To overcome these limitations, the circular DNA scaffold was introduced and has been divided into several subtypes ... stranded circular DNA template strand that is greater than 7,000 nucleotides ...

The DNA polymerases are divided into seven families based on their ... In this way, the integrity of the original DNA strand that is passed onto daughter cells is preserved. This family mainly ...

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a ...

“PDI is like a double agent,” Dr Shadfar explains. “In healthy cells, it repairs DNA and helps prevent disease. But in cancer ...

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 ...

making up the “backbone” of the DNA strand. Each sugar in a nucleotide has a nitrogen base attached to it. There are four different types of nitrogen bases in DNA. They include: adenine (A ...

Quantum mechanics, which rules the world of the teensy-tiny, may help explain why genetic mutations spontaneously crop up in DNA as it makes copies of itself, a recent study suggests. In ...

Zettabytes—that’s 10 21 bytes—of data are currently generated every year. All of those cat videos have to be stored somewhere, and DNA is a great storage medium; it has amazing data density ...
