Each of us has enough DNA to reach from here to the sun and back, more than 300 times. How is all of that DNA packaged so tightly into chromosomes and squeezed into a tiny nucleus? Long ...

In other words, a piece of DNA that is 1 meter long will become a "string-of-beads" chromatin fiber just 14 centimeters (about 6 inches) long. Despite this shortening, a half-foot of chromatin is ...

Many fields including biomedical research, forensics, and environmental monitoring rely on DNA extraction as a crucial process. DNA extraction marks the essential beginning of genetic information ...

which served as a foundation for adding shorter DNA strands. This process was akin to threading beads onto a string. Researchers then used a chemical reaction to attach a methyl group (CH3), a ...

With the exception of red blood cells, which contain no nucleus and no nuclear DNA, every one of these cells contains the human genome -- a string of three billion A's, C's, G's, and T's.
