the results of gel electrophoresis are shown below. what can you determine about the dna from looking at the results of this test? a. strand 3 is larger than strand 4 b. strand 2 is larger than strand 3

the results of gel electrophoresis are shown below. what can you determine about the dna from looking at the results of this test? a. strand 3 is larger than strand 4 b. strand 2 is larger than strand 3

Answer

Brief Explanations:

In gel - electrophoresis, larger DNA fragments move slower through the gel matrix and stay closer to the starting point (negative electrode), while smaller fragments move faster towards the positive electrode. Strand 3 is closer to the negative electrode compared to strand 4, indicating strand 3 is larger.

Answer:

A. Strand 3 is larger than strand 4
