If the amount of agarose added is more, the molecule under analysis should have following characteristic
(a) Small size
(b) Large size
(c) Size has no relation with amount of agarose
(d) Amount of molecules under analysis matters
Correct answer: (A) Small size
Explanation:
Higher agarose concentration → Smaller pores → Better resolution for smaller molecules
- Lower agarose concentration → Larger pores → Better resolution for larger molecules
Thus, if more agarose is added, the gel becomes denser, making it easier for small molecules to pass through, while larger molecules get trapped and move slower.
Why Not the Other Options?
-
(B) Large size ❌
- Large molecules migrate poorly in high-concentration agarose gels because of small pore size.
-
(C) Size has no relation with amount of agarose ❌
- Size is directly related to agarose concentration. More agarose = better resolution of smaller molecules, while lower agarose = better resolution of larger molecules.
-
(D) Amount of molecules under analysis matters ❌
- The quantity of sample affects band intensity, but not the resolution or separation efficiency.
Final Answer:
✅ (A) Small size

Anurag Giri
August 13, 2025Ans 1 Higher agarose concentration → Smaller pores → Better resolution for smaller molecules
Khushi Agarwal
August 13, 2025Option 1 is correct
If concentration increase then pore size decrease
Aman Choudhary
August 13, 2025option a is correct
because agarose does not have any crosslinker to reduce pore size if more addition of agarose the size become decrease
Soniya Shekhawat
August 13, 2025Concentration is inversely proportional to pore size
Soniya Shekhawat
August 13, 2025So small size is correct option.
Mohd juber Ali
August 14, 2025Option (a) Agarose gel ki concentration increase karne par pore size kam ho jate h only small molecule pass ho sakta h large molecule tarp ho jate h pore size kam hone se molecule small size…
Anjani sharma
August 14, 2025Answer 1 as the agarose concentration increase the pore size will decrease

Priya dhakad
August 14, 2025Answer 1st is correct if agarose concentration is increased then pore size small
Karishma Don
August 14, 2025increase concentration of agarose leads to small pores
Nilofar Khan
August 14, 2025Correct answer is a
Mansukh Kapoor
August 14, 2025The correct answer is option 1st
Small size because of more agarose is added than it becomes denser and it is easier to pass small molecules and large molecules trapped in it
Priyanka choudhary
August 14, 2025Correct answer the small size because of this the consentration is increase than pore size decrease
Sneha Kumawat
August 14, 2025Higher agro concentration hone pores size small ho jata hai jo small molecules ke liye better resolution deta hai

Dipti Sharma
August 14, 2025Higher agarose concentration means Smaller pores which gives better resolution for smaller molecules.

Priti khandal
August 14, 2025Option A is right sir small size because Agarose concertration is increase then pore size small

Divya rani
August 16, 2025Small size kyunki Agarose ki jyada concentration s chote pore bnenge yani chote molecules usme separate jyada Ache s honge
Aafreen
August 17, 2025Ans -1 small size
If more agarose is added the gel becomes denser it makes easier for small molecules to pass through it

High agarose concentration → small pores
Neeraj Sharma
August 18, 2025Option A small size is correct as the concentration is inversely proportional to pore size so the larger the agarose molecules more binding pore size less hence the molecule must be small to move easily and for better resolution
