RNA extraction and reverse transcription experiments are key technologies used in molecular biology to study gene expression and function. RNA extraction is the separation of complete, impurity-free RNA from cells or tissues, while reverse transcription is the conversion of RNA into cDNA for ...
The DNA of apoptotic cells is cut into fragments of about 200 base pairs under the action of caspase-activated nuclease (CAD), forming DNA ladders. By detecting DNA fragmentation during apoptosis, the degree of apoptosis can be evaluated.
