Children receive half of their genetic material from each parent. There are specific sites on DNA, known as restriction sites, that are recognized by restriction enzymes. These are used to determine paternity.
Samples of DNA from the mother, father and child are taken. They are all digested ('cut') by the same restriction enzymes. These DNA fragments are then separated by gel electrophoresis (which separates fragments based on size).
The bands of the child are compared to the mother and father's. If the band is not the same as the mother's, it must have come from the father. If these do not match up, then the sample was not taken from the biological father.

How does Maury use gel electrophoresis to determine paternity?
Maury uses gel electrophoresis to analyze DNA samples from a child and potential parents by separating DNA fragments based on their size. The process involves running the DNA through a gel matrix, where smaller fragments move faster than larger ones, creating distinct patterns or bands. By comparing these patterns, Maury can determine if the potential parent shares specific DNA markers with the child, thus establishing paternity based on genetic matches. This method provides a visual representation of genetic relationships, making it a reliable tool for paternity testing.
Is the DNA between double first cousins so similar as to be reliable to determine paternity?
DNA between double first cousins is usually not reliable enough to solely determine paternity. Although their DNA is more similar than that of unrelated individuals, there can still be significant variability that could lead to inconclusive results. For more accurate paternity testing, it is recommended to use DNA samples from the potential father and child.
Which technique was use to produce these bands?
Gel electrophoresis
Scientists use gel electrophoresis to cut dna at a specific nucleotide True or false?
It is true that Scientists use gel electrophoresis to cut DNA molecules at a specific sequence of nucleotides.
What is protein marker and what is its use in electrophoresis?
A protein marker is a mixture of proteins of known sizes that is run alongside unknown samples in electrophoresis. It is used as a reference to help estimate the size of the unknown proteins based on their migration pattern in the gel. This allows researchers to determine the size of proteins in their samples and compare them to standards.
What are the application of paper electrophoresis?
Paper electrophoresis is used to analyze scientific experiments. One use in scientific experiments for paper electrophoresis is to determine the presence of HIV from blood samples.
Can gel electrophoresis be used to determine the purity of an enzyme?
Gel electrophoresis can be used to assess the purity of an enzyme by separating different proteins based on size. If the enzyme appears as a single band on the gel, it suggests high purity. Contaminants or impurities would result in additional bands on the gel.

How can one effectively read an electrophoresis gel?
To effectively read an electrophoresis gel, first identify the direction of the gel and the size markers. Then, analyze the bands on the gel by comparing their positions and intensities to determine the sizes and quantities of the DNA or proteins present. Use a UV light or staining method to visualize the bands clearly.

What can one do with a DNA kit?
With a DNA kit you can use the swabs and a sample of your saliva to see if someone's DNA matches another person. This is often used to determine paternity of a child.
How do you know when a woman is cheating on you?
Use a polygraph (lie-detector). Or wait for 9 months, until she gives a birth of another man's baby, then make a paternity test in a hospital.
What is paternity testing?
It's genetic testing to determine what percentage likelihood a man is the biological father of a given child.
What is the most common reason for getting a Paternity test?
use a condom and you wouldn't necessarily need a paternity text. THINK!
Is tgge and dgge same thing?
Temperature Gradient Gel Electrophoresis (TGGE) is a refinement of Denaturing Gradient Gel Electrophoresis (DGGE). Both use the same principles.
