Molecular techniques

Definition

Molecular techniques refer to a set of laboratory methods used to analyze and manipulate biological molecules, primarily DNA, RNA, and proteins. These techniques are crucial for studying genetic material of parasites, allowing researchers to identify species, determine genetic diversity, and understand host-parasite interactions. They play an essential role in detecting and monitoring parasites in various environments, serving as valuable bioindicators of ecosystem health.
