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.
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.
What is RFLP used for?
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
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.
When one dna molecule replicated the result is two dna molecules what is true of the second dna molecule?
DNA actually has 3 forms. A-DNA, B-DNA, and Z-DNA. B-DNA is the kind you are most familiar with and present in most organisms. A-DNA can be found in dehydrated samples while Z-DNA is rare and mostly synthesized in the lab.
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 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.

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.
Does a molecule have DNA?
DNA is a molecule so no.

Is DNA an organic molecule?
Yes, DNA is an organic molecule.
Is DNA an organic or inorganic molecule?
DNA is an organic molecule.
What is involved in a DNA test?
The whole science behind it involves a process called agarose gel electrophoresis, which involves DNA being put on a buffer. First, a comb is placed on the left side of a box, on the negative side. Then, buffer is placed into the box until it cools and becomes solid, similar to frozen gel. Once cool, the agarose is poured onto the buffer so there is just a slight amount of agarose above the level of buffer. The comb is then taken out, leaving holes where the comb was. Then, the DNA is put into the holes made by the comb. There is an electric power supply that is attached to the box that contains buffer which the DNA was put upon, and when switched on, the electric power supply puts a charge on the agarose, making the DNA go all the way to the right (towards the positive side, since DNA is negatively charged). This will separate the DNA into RFLP's (Restriction Fragment Length Polymorphism). The RFLP's are not all the same length- the bigger RFLP's will move slower, and thus not move too far from the starting point, which was on the negative side on the left. The smaller RFLP's will move fast and far, spreading out the RFLP's by size. After about 2 hours, the electric power supply is turned off, leaving the RFLP's spread out by size. If you compare one human's DNA to any other human's DNA, there will be little difference. This is the same for every human. However, there is a slight difference in everyone's DNA. When the RFLP's are created after agarose gel electrophoresis, there will be some RFLP's that are different from others. When agarose gel electrophoresis is done for the DNA specimin found, the entire section of RFLP's should match up. If the RFLP's don't match up, than the person was not the culprit.
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.
