The gel below shows the result of sequencing a piece of DNA (the "template"). Each lane shows the fragments of the new strand (the "daughter" strand) that are produced when a given ddNTP is added to the PCR reaction. Based on these results, what is the sequence of the template (original) DNA strand? Please write (type) it out, making sure you indicate the 5' and 3' ends.
