A cell is replicating its DNA. Part of the DNA strand reads A-C-C-G-T-A-C. The new strand built off this section reads T-G-G-A-A-T-G. What effect might this have when the DNA replicates in the future?

• Cells having the new DNA version will look or operate differently from cells with the original DNA.

• Only the sections of DNA without mistakes will be used in the future so the DNA strand will shorten.

• The DNA will be exactly like the original since only the original strand of DNA is used as a template.

• When the new strand is used as a template the strand built from it will differ from the original DNA.
