RFLP (often pronounced "rif lip", as if it were a word) is a method used by molecular biologists to follow a particular sequence of DNA as it is passed on to other cells. RFLPs can be used in many different settings to accomplish different objectives. RFLPs can be used in paternity cases or criminal cases to determine the source of a DNA sample. RFLPs can be used determine the disease status of an individual. http://www.bio.davidson.edu/COURSES/genomics/method/RFLP.html
What else can I help you with?
What is a person's unique RFLP pattern?
sometimes, there isn't enough DNA found at a crime scene to be properly analyzed by forensic scientists. RFLPs are used to make exact copies of the DNA sequence so that it can be better analyzed in the lab.
Why is STR analysis better then RFLP analysis?
because STR only requires small pieces of DNA (2-5 base pairs long). it is fast and automated wheres RFLP can take up to a month to accomplish. STR is also better because it allows the use of the Polymerase Chain Reaction (PCR). whereas RFLP requires large amounts of non-degraded DNA and automation is not possible.
How is the DNA molecule divided in RFLP?
In RFLP analysis, the DNA molecule is first isolated from the sample. Then, it is digested with restriction enzymes to cut it into fragments at specific sites, creating a pattern of different lengths. These fragments are separated by size using gel electrophoresis, allowing for comparison of the fragment patterns between different samples.
Why do the number of DNA fragments and the length of each fragment produced by RFLP analysis differ from person to person?
As the DNA fragments results from the action of the restriction enzymes and on the other hand mutations alter the sites where the restriction enzymes react therefore there is difference in number and of length of each fragment from person to person.
The use of RFLPs are genetic fingerprinting is based on?
Originally, yes. RFLP stands for Restriction Fragment Length Polymorphism. An enzyme which cuts DNA is added to a sample of DNA purified from blood or whatever tissue is available for the test. The enzyme will cut DNA only at particular sites, yielding many segments of cut DNA. The pattern of cuts can be seen by taking this partially digested DNA and running it through a gel to separate the smaller fragments from the larger fragments. This produces a set of distinctive bands that are essentially unique to every individual on the planet, although members of the same family may have similar patterns.For more details, refer to http:/en.wikipedia.org/wiki/DNA_profiling .
What can be the main limiting factor in the use of RFLP?
What can be the main limiting factor in the use of RFLP?
In molecular biology RFLP is an acronym for what?
RLFP is an acronym for Resriction Fragment Length Polymorphism. RLFP analysis is used to identify changes in a genetic sequence that occurs at a site where a restriction enzyme cuts. RFLP's can be used to identify specific mutations and also trace inheritance patterns!
What is the difference between a gene and RFLP?
A gene is a specific sequence of DNA that contains the instructions for making a particular protein or RNA molecule, while RFLP (restriction fragment length polymorphism) is a technique used to detect variations in DNA sequences by cutting DNA with restriction enzymes and separating the resulting fragments by size. In other words, a gene is a functional unit of DNA, while RFLP is a method to study genetic variation at the DNA level.
What method is used to make DNA fingerprints?
A method known as RFLP (restriction fragment length polymorphism) analysis can be used to make a DNA fingerprint.
What is the full form of RFLP?

Is it possible for two people to have the exact same RFLP banding pattern?
It is highly unlikely for two people to have the exact same RFLP banding pattern due to the vast genetic variability among individuals. RFLP analysis is based on variations in DNA sequences, making it improbable for two unrelated individuals to have identical patterns.
What is the rflps?
Do you mean "RFLP" if so its, restriction fragment length polymorphism. (DNA analysis)

What Is made during an RFLP analysis?
During an RFLP (Restriction Fragment Length Polymorphism) analysis, DNA is digested with restriction enzymes, separated by gel electrophoresis, and transferred to a membrane for hybridization with a probe. The resulting pattern of DNA fragments of varying lengths is visualized to identify variations in DNA sequences between individuals.
