Study Notes
Advantages of AFLP
- Main advantage of AFLP over RAPD: ability to detect a large number of polymorphic bands in a single reaction
- Additional advantage of AFLP over RAPD: use of a combination of restriction enzymes and PCR primers to generate highly robust and reproducible markers
Gel Electrophoresis in AFLP
- Typically, a polyacrylamide gel is used for separating DNA bands in AFLP
Similarities between T-RFLP and DGGE
- Both T-RFLP and DGGE are molecular biology techniques used to analyze microbial communities
AFLP Digestion
- Unique step in AFLP compared to RFLP: PCR amplification of restricted fragments
- Primary function of MseI and EcoRI: restriction enzymes used to digest genomic DNA in AFLP, generating fragments for PCR amplification
Principles of RFLP
- Principle of Genomic DNA Restriction Fragment Length Polymorphism (RFLP): analysis of variations in the length of DNA fragments generated by restriction enzymes
High-Throughput Analysis Methods
- T-RFLP (Terminal Restriction Fragment Length Polymorphism) is a high-throughput analysis method commonly used for single species microbial fingerprinting
AFLP in Food Microbial Analysis
- In food microbial analysis, AFLP stands for Amplified Fragment Length Polymorphism
ARDRA and RFLP in Microbial Community Profiling
- What distinguishes ARDRA from RFLP: ARDRA (Amplified rDNA Restriction Analysis) targets the 16S rRNA gene, whereas RFLP targets the entire genome

Description
Test your knowledge of the principles of Restriction Fragment Length Polymorphism (RFLP) and its application in Random Amplified Polymorphic DNA (RAPD-PCR). Explore concepts like denatured DNA, non-specific PCR, and the use of smaller primers to produce a PCR 'fingerprint'. Identify the differentiation of yeast strains by RAPD-PCR, targeting variable regions within the genome.
