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 are the scientific uses for polyacrylamide?
it is used in gel electrophoresis.....for the separation of DNA fragments
Flouresecnt dyes are used in DNA electrophoresis?
Yes, fluorescent dyes are commonly used in DNA electrophoresis for visualizing DNA bands when they are exposed to ultraviolet (UV) light. These dyes bind to the DNA molecules to make them visible and easy to analyze. Examples of fluorescent dyes used in DNA electrophoresis include ethidium bromide and SYBR Green.
When is DNA cut during electrophoresis?
Electrophoresis technique is not designed to cut DNA molecule. When DNA is analyzed by electrophoresis to determine its molecular mass, the molecular biology engineer usualy digests the DNA molecule, before the electrophoresis, with specific enzymes called "restriction enzymes" in order to obtain fragments of diverse molecular weights that can be seen as bands in electrophoresis gels.
How are DNA fragments separated on DNA fingerprinting?
Gel electrophoresis
What is used to sort DNA into lengths?
Gel Electrophoresis
What is used to sort DNA into different lenghts?
Gel Electrophoresis
What are the common stains that is used after DNA electrophoresis?
Common stains used after DNA electrophoresis include ethidium bromide, SYBR Safe, and GelRed. These stains intercalate with DNA and allow visualization under UV light. They are used to detect and analyze DNA fragments separated on the gel.
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.
What is used to separate DNA fragments by size?

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.
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.
Why you do electrophoresis?
electrophoresis is the process of putting dyed DNA that has been cut by enzymes into a gel substance in order to seperate the DNA for genetic ID. It can be used for paternity testing comparing DNA of the child to the father.
What is the role of EtBr in electrophoresis?
Ethidium bromide interchalates with DNA. It doesn't affect electrophoresis, but it help visualise the DNA bands after electrophoresis. The EtBr that is bound to the DNA will fluoresce under ultraviolet light.
Difference between vertical and horizontal gel electrophoresis?
Horizantal gel electrophoresis is generally used for RNA/DNA based studies, while vertical gel electrophoresis is used for protein based studies.
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 the gel electrophoresis use for?
to separate proteins and DNA molecules according to their size and charge.
How is gel electrophoresis used in determining paternity?
Gel electrophoresis is used in determining paternity by separating DNA fragments based on their size. By comparing the DNA profiles of a child and potential father, scientists can determine if the father's DNA matches the child's, indicating paternity.
