A DNA Fingerprinting Exercise for
نویسنده
چکیده
"Hands on" laboratory exercises are excellent teaching tools because they have the potential to reach students with all types of learning styles. Unfortunately the large monetary investment required to obtain supplies and equipment and train instructors prevents many schools from providing hands-on learning experiences with DNA technology. Students in non-laboratory courses are even less likely to gain an appreciation for the types of information that can be obtained from DNA analysis. courses can include DNA analysis as a topic if this information is presented well in the absence of a lab. Therefore low cost alternatives to traditional laboratory exercises are desirable in order to convey principles of DNA technology to a wider variety of students. The importance of understanding DNA analysis is clear; as the use of DNA information becomes pervasive in society, everyone from a jury member to an individual applying for health insurance will have to make decisions about information derived from DNA analysis. At Seattle Central Community College, students use an exercise based on a DNA fingerprinting technique, RFLP analysis, to determine the identity of a criminal using evidence obtained from the scene of a crime. This learning exercise can be used in either a laboratory or lecture style course and can accommodate almost any budget, as the cost is limited to providing strips of paper and scissors. Although this exercise was originally designed as part of a genetics course for biotechnology majors, it has also been used successfully for non-science majors.

Background and Objective: The use of lactobacilli as probiotics requires the application of accurate and reliable methods for the detection and identification of bacteria at the strain level. Repetitive sequence-based polymerase chain reaction (rep-PCR), a DNA fingerprinting technique, has been successfully used as a powerful molecular typing method to determine taxonomic and phylogenetic relat...

DNA fingerprinting has become an important tool for diversity assessment and varietal identification in plant breeding programs. Semi- random PCR primers targeting intron-exon splice junctions (ISJ) were used to evaluate the potential of these markers in identification and classification of rice genotypes. A total of 12 ISJ primers were used for screening fourteen Egyptian rice genotypes, inclu...

Ten field isolates of Mycoplasma gallisepticum (MG) from different geographical areas of Iran were analyzed by random amplification of polymorphic DNA (RAPD). RAPD analysis produced reproducible banding patterns on the basis of which various distinct amplification patterns could be detected. MG isolates compared with reference strains (S6 and Mg SS) and vaccine strain (ts-11) and demonstrated...

Fusarium solain is the most important pathogen of huge range of plant hosts, especially potato in the word, which causes tuber rot in storage and root rot of potato plants in fields. Fifty four isolates from potato, bean, chickpea and cucurbit (melon, watermelon and cucumber) was subjected in a study through analysis of vegetative compatibility groups (VCGs) and rep-PCR DNA fingerprinting.
