DNA molecules are able to move through a gel due to (Pick all the correct choices can be multiple):
A. Diffusion
B. Electric fields
C. Buffers
D. Magnetic fields
Homework Answers
DNA molecules are able to move through a gel due to
B. Electric fields
Explanation-
DNA being negatively charged moves on the gel plate to the positive
terminal and this is total based on the size of the DNA particles
as the shorter ones travel quicker and to a greater distance than
the larger one's and hence are seperated.
C. Buffers
Explanation -
Buffers maintain the pH balance of the plate and provides the DNA
particles with suitable pH for easy movement and seperation.
A. Diffusion
Explanation -
Diffusion can too be regarded as one of the reason as due to
diffusion only the movement of macromolecules take place on the gel
plate be it be agar or agrose gel plate.
Magnetic field have no such role.
But most preferred and suitable answer is Electric field and Buffers.

Biologists use gel electrophoresis to sort DNA segments by size. DNA segments are placed at one end of a gel. DNA is negatively charged (with a charge of two electrons per base pair). When you “run the gel” you are generating an electric field by connecting anodes and cathodes at the ends of the gel. This causes the negatively charged DNA segments to move towards the positive electrode. After running the gel, smaller DNA segments have moved farther from the...

The picture above represents an agarose gel that was used to analyze plasmid DNA after it was cut with the restriction enzyme HindIll. The plasmid was incubated with Hindill until all of the available Hindlll cut sites were cut by HindIll. After running the sample on the gel, three bands were detected (Note that there are three wells shown at the top of the gel for loading samples, however, only the middle well was loaded with sample). Based on this...

Question 4-12 points Biologists use gel electrophoresis to sont DNA segments by size. DNA segments are placed at one end of a gel. DNA is negatively chargod (with a charge of two electrons per base pair). When you "run the gel" you are generating an electric field by connecting anodes and cathodes at the ends of the gel This causes the negatively charged DNA segments to move towards the positive electrode. After nunning the gel, smaller DNA segments have moved...

Why are MHC molecules able to bind a variety of peptides? Group of answer choices A. the peptide-binding groove of a specific MHC molecule can bind several peptides simultaneously B. The MHC genes undergo somatic recombination to produce thousands of MHC molecule variants C. MHC bind very loosely and transiently to peptide antigens, so a wide variety of peptide antigens can bind any specific MHC molecule D. a small number of amino acids in the peptide antigen bind specifically to...
