Definition of "DNA"

Among the various fractions isolated was one presumed to contain only desoxyribosenucleic acid (DNA). Because of certain speculations on the role of nucleic acids in protein synthesis it was necessary to measure and compare the rate of phosphate entry into DNA with that in other fractions of yeast phosphate.Desoxyribosenucleic acid is an archaic name of deoxyribonucleic acid.

As you know, heredity resides in our genes. Our genes are, in turn, composed of complex molecules called DNA. About 10 years ago we learned how to synthesize DNA in the test tube with the use of a certain cellular catalyst or enzyme. […] During the past year, we have been able to synthesize DNA which has the full genetic activity of natural DNA.

But this new fixation on guns is […] coming from the hardcore MAGA set, and not only is it likely to stick around beyond the primaries, it's likely hardwired into the DNA of a party now driven by extremism, conspiracy, and a belief that violence is a legitimate tool to achieve desired political outcomes.
