Remember that the 3 samples of DNA were orginally the samesize. Next, each sample was cut into pieces by the addition ofthree different restriction enzymes. 4. Compare the two methods-direct gel examination and semiloggraph-of determining the fragment size in base pairs. Which methodseems to be more accurate? Explain your answer.

Explanation / Answer
Of the two methods of direct gelexamination and semilog graph of determining the fragment size inbase pairs the semilog graph of determining thefragment size in base pairs is more accurate. This is because gel examination givesonly the rough idea of the distance travelled by the DNA fragmentsand we cannot examine the length accurately. Whereas when we take the graph we canextra plot the unknown sample in the standard graph and thencalculate the size of the fragment accurately. Hope this helps u.
