You can use a simple Agarose gel to separate to view the DNA on electrophoresis. Use 0.8 - 1% gel for 5-10kbp , 2% for 0.2 - 1kbp.
If the fragments are really tiny, use an Acrylamide gel (vertical gel) to electrophorese and they will show right out. This is to offset the instability of high concentration gels.

What is done to the DNA to make the bands visible in gel electrophoresis?
In gel electrophoresis, DNA is treated with a dye that binds to the DNA molecules, making them visible as bands under ultraviolet light.
What makes DNA visible?
You can an electrophoresis gel and then stain the gel using a solution such as coomassie blue to make the bands visible. Alternatively, you can stain a cell containing DNA by using acridine orange. It is necessary to observe these under an electron light microscope.
What step was necessary to make the DNA visible?
The DNA needed to be stained with a dye, such as ethidium bromide or SYBR Green, that binds to the DNA molecules and fluoresces under ultraviolet light. This allows the DNA to become visible when viewed under a UV transilluminator or gel documentation system.
How are DNA fragments separated and visualized in gel electrophoresis?
In gel electrophoresis, DNA fragments are separated based on size by applying an electric current to a gel matrix. The negatively charged DNA molecules move towards the positive electrode, with smaller fragments moving faster and traveling further through the gel. After separation, the DNA fragments can be visualized by staining the gel with a dye that binds to the DNA, making the bands visible under ultraviolet light.
Is Gel Electrophoresis used to make many copies of DNA?
no, it is used to separate different sized pieces of DNA using a gel and an electric current. Polymerase Chain Reaction (PCR) is the multiplication of DNA with the use of a PCR machine, enzymes and primers. The PCR machine allows the multiplication of DNA through temperature changes, activating each step of the reaction and copying DNA millions of times.

What instrument is used to load the DNA into the gel?
A micropipette or a loading dye is typically used to load DNA samples into the wells of an agarose gel.

How is PCR used in conjunction with gel electrophoresis to analyze DNA samples?
Polymerase chain reaction (PCR) is used to amplify specific regions of DNA in a sample. Gel electrophoresis is then used to separate the amplified DNA fragments based on size. By comparing the resulting DNA bands on the gel, scientists can analyze and identify the DNA samples.
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 is a gel used for in molecular biology research?
A"gel" generally refers to an agarose gel which is used to visualise DNA, determine the size of DNA and even a tell you a bit about its's structure (supoercoiled DNA vs linear DNA). However some gels can also be used to look at protein (often as a "western blot" gel) or RNA. The size of DNA, RNA or protein can be determined by how fast it moves across the gel when you pass an electrical current through it.
What is used to sort DNA into lengths?
Gel Electrophoresis
Which two methods are most often used in DNA fingerprinting?
The two most often used methods in DNA fingerprinting are polymerase chain reaction (PCR) and gel electrophoresis. PCR is used to amplify the DNA samples, while gel electrophoresis is used to separate the DNA fragments based on their size.
