Question

If the primers shown were used in a DNA analysis of person 1, 2, and 3, what order would the bands appear, from top to bottom, after running the gel?

Answer 1

Hello your question lacks the required diagram attached below is the missing diagram

answer : 1,3,2 ( b )

Step-by-step explanation:

Considering the gel electrophoresis the small fragment of 8 DNA long from the second person will move faster and reach the bottom then it will be followed by the 12 long DNA fragments of the third person, finally the transcribed DNA of person 1 to a length of 16 fragments long will follow i.e. The smaller fragments will move faster and they will settle at the bottom of the gel

hence option B is the correct answer
