Can electrolysis be used to separate DNA fragments?
Yep!
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.
What procedure is used to separate and analyze DNA fragments by placing a mixture of DNA fragments at one end of a porous gel and supplying an electrical voltage to the gel?
agarose gel electrophoresis
Where do you get the DNA fragments for Gel electrophoresis?
The DNA fragments comes from the method of DNA isolation.
What are okazaki fragments used to elongate?
Okazaki fragments are used to elongate the lagging strand. These fragments are used as primers for RNA polymerase to fill up the gaps in the newly formed complimentary DNA on the lagging strand. DNA ligase then seals up the gaps.

What is the role of Ficol in DNA quantification?
Ficoll, basically polysucrose is used to prepare density gradients during centrifugation to separate DNA fragments.
What explains the role of gel electrophoresis in forensic science?
It is a special technique used to separate and identify DNA fragments.
What tool does one use to separate DNA fragments?
a Polyacrylamide gel
Gel electrophorysis and GMO food?
Gel electrophoresis is a method for separation and analysis of macromolecules (DNA, RNA and proteins) and their fragments, based on their size and charge.The tool of DNA gel electrophoresis was developed in the 1970s. The process uses electricity to separate DNA fragments by size as they migrate through a gel matrix.It can be used to separate proteins that are used in genetically modified foods.
Are restriction enzymes used in gel electrophoresis?
For DNA gel electrophoresis, yes. Once the DNA is cut up into different-sized fragments, they can be electrophoresed to separate bands.
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 enzyme binds fragments of DNA on the lagging strand?
The enzyme that is used to bind DNA fragments together is DNA ligase. Using DNA ligase to join DNA fragments is the last step in the production of a recombinant DNA plasmid.
One function of gel electrophoresis is to?
To separate strands of DNA based on their size. Shorter strands will migrate more slowly than larger strands. ** Also because DNA is slightly negatively charged, it will move toward the positive end of the electrodes... this is why the current is used when running a gel. Short strand move further** than large ones due to the gel resistance.
How is a DNA FINGERPRINT PRODUCES?
Selected fragments are used to produce a DNA fingerprint.
