Scientists have taken advantage of the power of DNA polymerase molecules to copy DNA molecules in test tubes via polymerase chain reaction, also known as PCR.

Watch the white material come out of solution as a precipitate. This is the DNA. Dip the glass rod into the tube, slowly rotating it to spool the banana's DNA around the rod. Observe the DNA in ...

Your DNA data contains highly sensitive information about your health and identity. Everything from your ancestry to your risk of cancer to information about allergies and predisposition to ...

would interact with an OR logic gate DNA molecule. Then in a fluid-filled tube, the input oligonucleotide interacted with a logic gate DNA molecule and generated an output oligonucleotide.

combine 100 μl of 2.5 M CaCl 2 with 25 μg of plasmid DNA in a sterile 5-ml plastic tube and, if necessary, bring the final volume to 1 ml with 0.1× TE (pH 7.6). Mix one volume of this 2× ...

“You can't get the chimps to spit in a tube and send it off to 23 and Me," said Arizona State University professor and study co-author Kevin Langergraber. He says the team found genetic differences ...
