b.They lack organelles such as chloroplasts.
c.They are less complex than eukaryotic cells.
d.They lack genetic information.
e.They lack a true nucleus.
____C_ 2. In order to be functional, a eukaryotic chromosome requires all of the following EXCEPT:
a.A centromere.
b.Origins of replication.
c.A centrosome.
d.Telomeres.
___C__ 3. Alfred Hershey and Martha Chase examined transformation using bacteriophage (bacterial DNA virus) and bacterial cells. If phage are labeled with radioactive phosphate and allowed to infect bacterial cells, the radioactive phosphate will be localized to:
