Which is a common cause of cervical cancer	human papillomavirus
which of the following is correct about both binary fission and meiosis	both replicate the DNA before the cell splits
Eukaryotic chromosomes become visible with a light microscope before cell division because they	become more tightly wound
the first sign of cytokinesis in an animal cell is the formation of a	cleavage furrow
