Nitrogenous base,purines and pyrimidines are the two categories of nitrogenous bases,pentose sugar,in DNA the sugar is 2'-deoxyribose,Phosphate Group,a single phosphate group is PO 4.
1 DNA and RNA base pairing is slightly different, since DNA uses the bases adenine, thymine, cytosine, and guanine; RNA uses adenine, uracil, cytosine, and guanine. 2  Uracil differs from thymine in that it lacks a methyl group on its ring. RNA nucleotides are defined by the sugar ribose, and contain a slightly different set of nitrogenous bases: adenine, guanine, cytosine, and uracil. RNA molecules do not contain thymine. Unlike DNA, RNA is usually present in a single-stranded form. In addition, because they are copied from only a limited region of the DNA, RNA molecules are much shorter than DNA molecules. A DNA molecule in a human chromosome can be up to 250 million nucleotide-pairs long; in contrast, most RNAs are no more than a few thousand nucleotides long, and many are considerably shorter. A nucleotide consists of a sugar, a phosphate and a nitrogenous base. In RNA the sugar is ribose, in DNA it is deoxyribose. DNA contains the bases A, T, C and G. RNA contains … the bases A, U, C and G. 1 person found this useful. * a nitrogenous base (cytosine, guanine, adenine, or uracil) - this is important for making the RNA code for an amino acid, essentially this is where the information is transmitted by the RNA. * a ribose sugar-this is an important difference between RNA and DNA, as DNA contains a deoxygenated ribose molecule. 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. Here's the answer for both DNA and RNA. Answer: Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts: 1  Nitrogenous Base. 2  Purines and pyrimidines are the two categories of nitrogenous bases. 3  Pentose Sugar. 4  In DNA, the sugar is 2'-deoxyribose. 5  Phosphate Group. 6  A single phosphate group is PO 4 3- .
