1) Compare and contrast Prokaryotic cell division and Eukaryotic cell division

homologously paired chromosomes haploid or diploid?
3) How do autosomes differ from sex chromosomes? How many pairs of sex chromosomes
do humans have? How many pairs of autosomes do humans have?
4) Draw a metacentric, acrocentric and telocentric chromosome.
