Answer:
Uracil
Explanation:
RNA stands for ribonucleic acid. This helps with the expression of genes.
Bases of RNA
RNA has 4 different bases: adenine (A), uracil (U), cytosine (C), and guanine (G). Next to each base, you can see the symbol that represents the base. These bases are called nitrogenous bases because they contain nitrogen and act as a base (as opposed to an acid). These monomers are one of the building blocks of nucleic acids.
In RNA, adenine and uracil bond, and cytosine and guanine bond.
DNA
RNA and DNA are commonly confused because they perform similar jobs, but nonetheless, they are different. One reason they are different is that DNA does not have uracil. In DNA, adenine bonds with thymine (T).
