A)electron microscope
B)radioactive staining
C)fluorescent staining
D)DNA stain and a light microscope
E)a stain particular to human cells

Accepted Answer

To view and analyze human chromosomes in a dividing cell, DNA stain and a light microscope are required. DNA stain will label the chromosomes while a light microscope will enable the observer to see the stained chromosomes. An electron microscope is not necessary for visualizing chromosomes in dividing cells. Radioactive staining and fluorescent staining can be used to label chromosomes, but they still require a light microscope to observe. A stain particular to human cells is not necessary as all human cells contain the same genetic material.
