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. Both DNA and RNA are nucleic acids, and are polymers of nucleotides. A nucleotide has three components: a pentose (five-carbon sugar), and attached to different parts of it a phosphate group and a nitrogenous base (either a purine or a pyrimidine).he monomers of DNA are deoxyribonucleotides, because their sugar is deoxyribose. The nucleotides in a nucleic acid are not all identical. There are four kinds in each nucleic acid, differing only in their bases. The bases in the nucleotides of RNA are cytosine, uracil, adenine, and guanine.
