Does Dna Contain the Nitrogenous Base Uracil?

Uracil is one of four nitrogenous bases found in the RNA molecule: uracil and cytosine (derived from pyrimidine) and adenine and guanine (derived from purine). ... Deoxyribonucleic acid (DNA) also contains each of these nitrogenous bases, except that thymine is substituted for uracil.

Does DNA contain uracil?

Uracil is a nucleotide, much like adenine, guanine, thymine, and cytosine, which are the building blocks of DNA, except uracil replaces thymine in RNA. So uracil is the nucleotide that is found almost exclusively in RNA. Lawrence C.

Is there A nitrogenous base in DNA?

DNA is a long molecule, made up of lots of smaller units. To make a DNA molecule you need: nitrogenous bases—there are four of these: adenine (A), thymine (T), cytosine (C), guanine (G) carbon sugar molecules.
