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.
DNA is a very large molecule, made up of smaller units called nucleotides that are strung together in a row, making a DNA molecule thousands of times longer than it is wide. Each nucleotide has three parts: a sugar molecule, a phosphate molecule, and a structure called a nitrogenous base.The nitrogenous base is the part of the nucleotide that carries genetic information, so the words nucleotide and base are often used interchangeably.The bases found in DNA come in four varieties: adenine, cytosine, guanine, and thymineoften abbreviated as A, C, G, and T, the letters of the genetic alphabet.ach nucleotide has three parts: a sugar molecule, a phosphate molecule, and a structure called a nitrogenous base.
