NEET Solved Paper 2017 Question 57
Question: What is the criterion for DNA fragments movement on agarose gel during gel electrophoresis?
Options:
A) Negatively charged fragments do not move
B) The larger the fragment size, the farther it moves
C) The smaller the fragment size, the farther it moves
D) Positively charged fragments move to farther end
Show Answer
Answer:
Correct Answer: C
Solution:
- During agarose gel electrophoresis, DNA fragments are separated based on their size. Smaller fragments move faster and farther through the gel matrix compared to larger fragments. This is because the gel acts as a sieve, allowing smaller molecules to pass through more easily than larger ones.
