Correct answer: A. move faster and travel farther through the gel
- A. move faster and travel farther through the gel
- B. remain near the wells
- C. dissolve in the buffer
- D. become positively charged
Explanation
The gel acts as a molecular sieve, so small fragments slip through its pores more easily than large ones. Fragment size can therefore be read directly from the distance travelled.
