to identify specific dna pattern in one individual, dna fingerprinting dna 指紋分析 can be used. among the non-coding dna (>95% in human genome), there are two kinds of dna segments that can be used in fingerprinting. they are with different number of repeats, different lengths of the vntrs can be obtained after cutting by   restriction enzyme  .

a dna fingerprint can then be obtained after dna denaturation, adding dna probes and staining. being amplified by   polymerase chain reaction (pcr)  , fragments of strs can be separated by gel electrophoresis. since the strs are located in highly variable region, no dna denaturation and dna probes are needed. in embryo screening, coding dna will be analyzed instead of vntrs and strs.

assemble a virtual dna fingerprint and use it to identify the culprit in a first, you’ll create a dna fingerprint (we’ll supply the lab and all instead, by marking a small number of segments of dna in one sample and then your search for “dna fingerprinting (slm5343)” returned 28 results. answer sheets, and templates are available for topics on dna’s history, code, gel electrophoresis, genome, this is a virtual laboratory experiment on dna fingerprinting. may use dna fingerprint to provide biological evidence as a proof in a dna may be extracted from red blood cells found in a blood sample.

unless you have an identical twin, your dna is different from that of every other person in the world. experts can use dna fingerprints for everything from determining a biological mother or father to identifying the suspect of a crime. then you’ll compare this dna fingerprint to those of all seven suspects to nab the perpetrator. in the last 15 years, dna has played an increasingly important role in our legal system. fortunately, the genetic comparison doesn’t require that investigators look at all of the dna found in the tissue samples.

instead, by marking a small number of segments of dna in one sample and then checking for the presence or absence of those segments in the other sample, investigators can say with some assurance whether the samples are from the same person. investigators use chemicals to cut the long strands of dna into much smaller segments. next, they introduce a small set of radioactive “markers” to the sample. these markers are segments of dna of known length, with bases that complement the code of, and bind to, sample segments of the same length. the final step is a relatively simple matter of lining up the sample profiles side by side and comparing them for the presence or absence of segments with particular lengths. the more segments the two samples have in common, the more likely it is that the samples came from the same person.
