Since 1933, Navy Federal Credit Union has grown from seven members to over 7 million members. And, since that time, our vision statement has remained focused on serving our unique field of membership: âBe the most preferred and trusted financial institution serving the military and their families.â
Like DNA, RNA polymers are make up of chains of nucleotides. These nucleotides have three parts: 1) a five carbon ribose sugar, 2) a phosphate molecule and 3) one of four nitrogenous bases: adenine, guanine, cytosine or uracil. RNA nucleotides form polymers of alternating ribose and phosphate units linked by a phosphodiester bridge between the #3 and #5 carbons of neighboring ribose molecules. RNA nucleotides differ from DNA nucleotides by the presence of a hydroxyl group linked to the #2 carbon of the sugar.
Nucleotides are the subunit that is polymerized (connected into a long chain) to make nucleic acids (DNA and RNA). Nucleotides consist of three smaller components: a ribose sugar, a nitrogenous base, and phosphate group(s). Generic nucleotide structure. The connection that forms between nucleotides is between the sugar of the first nucleotide and the phosphate group of the second. 2  Each connection between nucleotides is a covalent bond, so the nucleic acids have a covalently attached sugar-phosphate backbone.
