When a living cell is ready to divide into two new cells, the two sides of the DNA molecule separate by neutralizing the hydrogen bonds linking the purines and the pyrimidines. Instead of using RNA on a section of the DNA ladder, the whole ladder separates and new nitrogenous bases are a...

Adenine and guanine in DNA are purines. 10 Pyrimidines Found in foods like beans, peas, and grains. A diet high in pyrimidine sources is less likely to contribute to gout. 12 Purine Involved in energy transfer within cells. ATP, a key energy molecule, is a purine nucleotide. 7 Pyrimidine...
Purine bases never bond with other purine bases and pyrimidine bases never bond with other pyrimidine bases. Specifically, cytosine always pairs with guanine and adenine pairs with thymine or uracil, depending on whether in a DNA or RNA molecule. This pairing is referred to as specific base ...
1. Adenine (A) - Adenine (6-Adminopurine), C5H5N5, is a purine type of nucleobase, containing two rings of alternating carbon and nitrogen atoms. Adenine (A) always pairs with Thymine (T) to form an A-T pair. 2. Cytosine (C) - Cytosine (2-Oxo-4-adminopyrimidine), C4H5N3O,...

Purines and Pyrimidines:A basic crystalline compound that forms hydrogen bonds. They are the two basic types of nitrogenous bases that form the nucleotide bases found in DNA and RNA. Monomer:A molecule that can be bonded to other identical molecules to make a polymer (see below). Remember th...
