Chromosome jumping was also used in isolating the CF gene. It is similar to chromosome walking, but eliminates the need to detect overlapping regions Figure 8.

Partial restriction digestion produces large overlapping DNA fragments. Fragments arc circularized with DNA ligase, bringing ends that were some distance apart together. Resulting circles are cut to release the junction region, which is cloned to form a jumping library.
When a probe detects a homologous DNA in the library it will be associated with DNA from some distance away in the chromosome. The associated DNA is then used as a probe to make another jump in the library, or as the starting point for chromosome walking. Identifying a gene of interest in a set of clones is a challenge. Cloned DNA was used as a probe against genomic DNA of other species, because genes are likely to be more conserved than nongene sequences. Genomic fragments from a variety of species were analyzed by Southern hybridization a zoo blot.
DNA probes from genes are expected to hybridize with mRNAs in a Northern, and this technique can test whether a sequence is transcribed.
This probe identified a single cDNA clone by Northern blot, and that clone was then used to find the genomic CF sequences. Isolation of the CF gene was confirmed when DNA sequences in this region proved to be different in a normal and a CF individual, showing a deletion of 3-bp in the CF patient. Computer analysis of the CF gene predicts that the CFTR cystic fibrosis transmembrane conductance regulator protein has two similar membrane- association motifs, and an ATP binding domain.
The common CF mutation removes phenylalanine from the 1st predicted protein domain. Relevant molecular markers include: a. RFLPs detected by restriction digestion and blotting. PCR product polymorphisms detected by agarose gel electrophoresis. Alleles detected by allele-specific oligonucleotides ASOs. Highly polymorphic DNA regions are preferred for typing, and great variation is shown in regions of DNA consisting of short tandem repeats: a.
Microsatellites, also called single tandem repeats STRs , have repeating units of 2—4 bp b. Minisatellites, also called VNTRs variable number of tandem repeats , have repeating units ranging in size from 5 to a few tens of base pairs.
The size variation is detected by probing for the particular repeat sequence. The probe may be specific for STR or VNTR sequences at one genomic locus a monolocus or single-locus probe or at a number of loci a multilocus probe. DNA typing in a paternity case would proceed as follows Figure 8. DNA samples typically from blood are obtained from mother, baby and putative father. DNA is cut with a particular restriction enzyme, electrophoresed and transferred to a membrane filter by Southern blotting.

Baby and mother are expected to share one allele, while baby and father share the other allele. If the man and baby do not share a common allele, DNA typing has proved he is not the father. If they do share an allele, paternity is possible, but not proven, since other men also carry the allele at some frequency that can be calculated.
Often five or more different polymorphisms are characterized. If all match with the putative father, the combined probabilities calculated for the array of polymorphisms can be convincing evidence in court. The role of DNA typing in court cases is still being determined, and DNA typing is not generally accepted for proving parenthood or guilt, although it is widely used as evidence of innocence.
DNA evidence is most commonly rejected for procedural reasons, such as errors in evidence collection or processing, or due to lack of population statistics for the alleles in question. Examples of DNA typing used to analyze present-day samples include: a.
