Q.
Study the given figure carefully and select the correct statements regarding this
I. It represents typical agarose gel electrophoresis which showing differential migration of DNA fragments II. Lane 1 contains undigested DNA fragments III. Lanes 2 to 4 contains digested DNA fragment IV. Smallest DNA bands are present at ($A$) position and largest DNA bands are present at ($B$) position
A) I, II and III
B) I, II and IV
C) II and III
D) III and IV
Explanation
Largest DNA bands will be at (A) and smallest DNA bands will be at (B) because in this DNA is move according to their size in agarose small DNA fragment will have small resistant so this fragment move to long distance as compared to large DNA fragment
