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 ...

DNA repair can be divided into a set of mechanisms that identify ... by AP endonuclease before the nucleotide gap in the DNA strand is filled by DNA polymerase. Nucleotide excision repair is ...

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 ...

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.

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 ...

Rather than hand-threading each DNA strand, the team assembles strands from pre-built DNA bricks about 20 nucleotides long, encoding information by altering some and not others along the way.

DNA may embody the blueprint of life, but it could also be the stuff of future nanotechnologies. In a feat of molecular engineering, scientists recently designed a strand of DNA that can ...

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 ...
