Vedclass · Answer

(A) The $Feulgen$ reaction is a specific staining technique used in histology and cell biology to detect chromosomal material or $DNA$ in cell nuclei.It involves the mild acid hydrolysis of $DNA$,which exposes aldehyde groups on the deoxyribose sugars.These aldehyde groups then react with Schiff's reagent to produce a distinct magenta or purple color.Since $DNA$ is the target molecule for this reaction,the correct answer is $DNA$.
