<span>In genetics, complementary DNA (cDNA) is double-stranded DNA synthesized from a messenger RNA (mRNA) template in a reaction catalysed by the enzyme reverse transcriptase. cDNA is often used to clone eukaryotic genes in prokaryotes.</span>
The formula for this reaction would be
N + H3 ---> NH3
The first part of the reaction are the reactants and the second part is the product.
The reactants of this reaction are N and H3.
Or you could say the reactants are nitrogen and hydrogen
