Nucleases are enzymes that catalyze the hydrolysis of phosphodiester bonds in DNA or RNA. They play fundamental roles in nucleic acid extraction, sample purification, contamination control, and molecular experiment quality control.
Rt-qPCR (real-time fluorescence quantitative PCR) is a basic experiment in molecular biology, which mainly includes three steps: RNA extraction, reverse transcription to cDNA, and real-time fluorescence quantitative PCR.
