A nucleotide can contain nitrogenous bases other than purines and pyrimidines, for example, nicotinamide mononucleotide is a compound of the base nicotinamide with a ribose and a phosphoric acid residue. If more phosphates bond to the nucleotide (nucleoside monophosphate) it can become a nucleoside diphosphate (if two phosphates bond), or a nucleoside triphosphate (if three phosphates bond), such as adenosine triphosphate (ATP). What I'm saying is, I don't think the baby could inherit its parents nucleotide sequences for albino and then "fix" them during the formative stages, but rather the baby eitehr has albino nucleotide sequences or has non-albino nucleotide sequences and stays whichever way it ends up. A protagonist is the main character of a story, or the lead. Single nucleotide polymorphisms, frequently called SNPs (pronounced “snips”), are the most common type of genetic variation among people. Three nucleotides merit special consideration because of their specialized roles in cellular function. The two chains in the double helix are held together along their length by hydrogen bonds that form between the bases on one chain and the bases on the other. A nucleotide is composed of three distinctive chemical sub-units: a five-carbon sugar molecule, a nitrogenous base—which two together are called a nucleoside—and one phosphate group.With all three joined, a nucleotide is also termed a "nucleoside monophosphate", "nucleoside diphosphate" or "nucleoside triphosphate", depending on how many phosphates make up the phosphate group. Nucleic acids are made up of long chains (polynucleotides) of such compounds. The portion of the nucleotide molecule that doesn't include the phosphate group is called a nucleoside. Copyright © 2011.
