How do you do RFLP step by step?

What are the steps of RFLP?

  1. Isolate DNA.
  2. Perform PCR.
  3. Perform Restriction Digestion.
  4. Prepare Sample for Analysis.
  5. Perform Capillary Electrophroesis.
  6. Analyze Data.

How is RFLP analysis used in forensic DNA analysis?

  • Restriction fragment length polymorphism (RFLP) analysis was one of the first forensic methods used to analyze DNA. RFLP analysis requires investigators to dissolve DNA in an enzyme that breaks the strand at specific points. The number of repeats affects the length of each resulting strand of DNA.

What does RFLP stand for?

  • Restriction Fragment Length Polymorphism (RFLP) The RFLP probes are frequently used in genome mapping and in variation analysis (genotyping, forensics, paternity tests, hereditary disease diagnostics, etc.).

How are the probes screened for RFLPs?

  • The probes are screened for RFLPs using genomic DNA of different genotypes digested with restriction endonucleases. Typically, in species with moderate to high polymorphism rates, two to four restriction endonucleases are used such as EcoRI Isolation of sufficient DNA for RFLP analysis is time consuming and labor intensive.

What is the RFLP analysis technique?What is the RFLP analysis technique?

RFLP analysis technique involves cutting a particular region of DNA with known variability, with restriction enzymes, then separating the DNA fragments by agarose gel electrophoresis and determining the number of fragments and relative sizes. A restriction enzyme is an enzyme, a protein molecule, that cuts DNA at restriction sites.

How is the DNA cut in RFLPs?How is the DNA cut in RFLPs?

In RFLPs the DNA is cut using a restriction enzyme, an enzyme that cuts the DNA only where it recognizes a specific sequence of nucleotides (a restriction site). The pieces vary in size based on the location of the restriction sites.

Isolation of sufficient DNA for RFLP analysis is time consuming and labor intensive. However, PCR can be used to amplify very small amounts of DNA, usually in 2-3 hours, to the levels required for RFLP analysis.
