The rate at which large DNA fragments move through the electrophoretic gel is?
The rate at which large DNA fragments move through the electrophoretic gel is slower compared to small DNA fragments because larger fragments experience more resistance as they navigate through the gel matrix. This results in larger DNA fragments being located closer to the well where they were loaded onto the gel, while smaller fragments move further down the gel towards the positive electrode.
How does gel electrophoresis separate DNA by size?
Gel electrophoresis separates DNA fragments based on their size through an electric current. The negatively charged DNA molecules move towards the positively charged end of the gel. Smaller fragments move faster and migrate further through the gel than larger ones, resulting in the separation of DNA fragments by size.
How can gel electrophoresis be used to separate and analyze DNA fragments?
Gel electrophoresis separates DNA fragments based on size by applying an electric field to move them through a gel matrix. Smaller fragments move faster and travel further, allowing for analysis of DNA size and quantity.
Explain how an agarose gel can separate DNA fragments of different lengths.?
The separation of DNA fragments is based on size. When a DNA sample is run in a gel (electrophoresis), the lighter fragments migrate faster than the heavier (longer) fragments under the influence of an electric current. At the and of the process, the shorter fragments are found at the terminal end of the gel and the longer fragments closer to the origin
What is the technique that gel electrophoresis uses to separate and analyze DNA fragments based on their size and charge?
Gel electrophoresis separates and analyzes DNA fragments by passing an electric current through a gel matrix, causing the DNA fragments to move based on their size and charge.

After DNA is cut with a restriction enzymes how is the mixture of DNA fragments sorted?
The mixture of DNA fragments can be sorted using gel electrophoresis. In this process, the DNA fragments are separated based on size as they move through a gel under an electric field. The smaller fragments move further and faster than the larger ones.
How does agarose gel electrophoresis work to separate DNA fragments based on their size?
Agarose gel electrophoresis separates DNA fragments based on their size by using an electric current to move the fragments through a gel made of agarose, a substance derived from seaweed. Smaller DNA fragments move faster through the gel, while larger fragments move more slowly. This separation occurs because the gel acts as a sieve, with smaller fragments able to navigate through the pores more easily than larger fragments. As a result, the DNA fragments are separated into distinct bands based on their size when viewed under ultraviolet light.
How can an agarose gel facilitate the separation of DNA fragments?
An agarose gel can facilitate the separation of DNA fragments based on their size. When an electric current is applied to the gel, the negatively charged DNA molecules move through the gel towards the positive electrode. Smaller DNA fragments move faster and travel further through the gel than larger fragments, resulting in distinct bands that can be visualized and analyzed.
What is used to separate DNA fragments by size?
Electrophoresis. Restriction enzymes are used to cut DNA into fragments. Solutions containing these fragments are placed on the surface of a gel to which an electric current is applied. The electric current causes the DNA fragments to move through the gel. Because smaller fragments move more quickly than larger ones, this process separates the fragments according to size.
How does gel electrophoresis separate DNA by size?
Gel electrophoresis separates DNA fragments based on their size through an electric current. The negatively charged DNA molecules move towards the positively charged end of the gel. Smaller fragments move faster and migrate further through the gel than larger ones, resulting in the separation of DNA fragments by size.

Why does the DNA fragment size change as you move from the cathode to the anode?
In gel electrophoresis, DNA fragments move towards the anode (positive electrode) because DNA is negatively charged. Smaller fragments move faster through the gel matrix, so they appear closer to the anode while larger fragments move slower and appear closer to the cathode. This results in separation of DNA fragments based on size.
What is the technique that gel electrophoresis uses to separate and analyze DNA fragments based on their size and charge?
Gel electrophoresis separates and analyzes DNA fragments by passing an electric current through a gel matrix, causing the DNA fragments to move based on their size and charge.
What causes the difference in how far different DNA fragments move through an agarose gel?
The difference in how far DNA fragments move through an agarose gel is primarily influenced by their size. Smaller DNA fragments navigate through the porous matrix of the gel more easily than larger ones, allowing them to travel further in a given time. Additionally, the gel concentration can affect the mobility of the fragments; higher concentrations create smaller pores that hinder the movement of larger DNA. Overall, this size-dependent mobility is used in techniques like gel electrophoresis to separate DNA fragments for analysis.
Why does DNA move through the gel during electrophoresis?
During electrophoresis, DNA moves through the gel because it is negatively charged due to the phosphate groups in its backbone. When an electric field is applied, the negatively charged DNA is attracted towards the positive electrode, causing it to migrate through the gel matrix. Smaller DNA fragments move faster through the gel than larger fragments.
