Golden Earring were by now a different band again, producing slick pop-rock that was perfectly placed to capitalise on both the rise of AOR and the birth of MTV. The usual explanation for Twilight Zone's success is that its stylish, cinematic promo clip became a staple of the young music network, and that's true.
Pyrimidine: A nitrogen containing, single ring compound that occurs in nucleic acids. In DNA molecules, the pyrimidines are cytosine and thymine. Radioactive phosphorus (32P): radioactive isotope of 31P, an element found in DNA molecules.
The purines are made up of two-carbon nitrogen ring bases with four nitrogen atoms while the pyrimidines are made up of one-carbon nitrogen ring bases with two nitrogen atoms. These two compounds serve as building blocks for a wide variety of organic compounds that can be found in nature and in our bodies.n microbiology, there are two types of nitrogenous bases that make up the two different kinds of nucleotide bases in DNA and RNA. These two types are called purines and pyrimidines.
