A 1.2% Agarose Gel will separated DNA based on . O charge only both charge and size O size only neither charge nor size Question 2 A 1.2% Agarose Gel will separated dyes, proteins and amino acids based on . charge only both charge and size Osize only neither charge nor size Methylene Blue is a positively-charged dye. Which of the following components of DNA will it bind? purine bases O pyrimidine bases Dye will bind to all these DNA components O deoxyribose sugar phosphate group Question 6 Select the three parts of a DNA nucleotide. ribose monosaccharide deoxyribose nitrogenous base amino acid phosphate

Answer 1

answers are marked in circle

explanation as follows

1. a agarose gel electrophoresis seperate DNA molecule on the basis of its charge, mass, size and shape lower the value of these factor DNA move fast in gel and higher the value of these factors DNA moves slowly on gel.

2. agarose gel separate dye, protein and amino acids on the basis of its charge and size because different charge and size have different mobility in electric field ( and principle of electrophoresis is that separation of biomolecules on the basis of their charge, mass, size, shape in electric field.)

3. methylene blue is positively charge dye which bind to phosphate group of DNA because in DNA phosphate group is negatively charged and it is main reason why DNA has negative charge.

4.DNA( Deoxyribose Nucleic Acid) it is polymer of nucleotide which is composed of deoxyribose sugar, nitrogenous base( A,T,G,and C)and phosphate group)

Methylene Blue is a positively-charged dye. Which of the following components of DNA will it bind? purine bases Opyrimidine bases Dye will bind to all these DNA components O deoxyribose sugar O phosphate group

Question 6 Select the three parts of a DNA nucleotide ribose Omonosaccharide deoxyribose nitrogenous base amino acid phosphate

Question 2 A 1.2% Agarose Gel will separated dyes, proteins and amino acids based on charge only both charge and size size only neither charge nor size
