Answer:
microscopy, cell culturing, DNA tagging
Explanation:
Microscopy: is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye.
Cell culture: is one of the major tools used in cellular and molecular biology, providing excellent model systems for studying the normal physiology and biochemistry of cells
Immunostaining: histopathology for the diagnosis of specific types of cancers based on molecular markers.
DNA tagging: Gene tagging Gene tagging refers to the identification of existing DNA or the introduction of new DNA that can function as a tag or label for the gene of interest.
