The diagram below shows a segment of DNA with a total length of 4900 base pairs (the base letters are not shown). The arrows indicate recognition sites for two different restriction enzymes (enzyme X and enzyme Y). The numbers indicate how many base pairs in between each restriction site and/or the ends of the DNA segment. A) If the DNA was treated with restriction enzyme X ONLY, how many DNA fragments would be produced? B) What would be the length of the largest fragment?
