How can a person's muscle cells have the same exact DNA sequences as their nerve cells even though they look and perform completely different?

• The two different cells become mutated

• The proteins expressed in each cell are different

• They actually have different DNA in the two types of cells.

• The genome of the different cells changes

Replication in prokaryotes differs from replication in eukaryotes for which of these reasons?

• Prokaryotic chromosomes have a single origin of replication, whereas eukaryotic chromosomes have many.

• Prokaryotes produce Okazaki fragments during DNA replication, but eukaryotes do not.

• primase

• DNA ligase

• DNA Polymerase

• helicase
