i have searched the web for a good web site that would help with that question and found one that might be wat ur looking for try it and see. just click on the link below.

figure out the efgfect of the enzyme. Or you can test DNA structure. Inhibitary enzymes have a blacked actionsite whereas activation enzymes have activation sites open to substrates

The biological stamp should be something connected to the genetic make-up and the DNA of an individual. But the most visible and verifiable one is one's fingerprint. This is quite unique to individuals.

well, its a little more complicated than the above person mentions.\n\nAside from finding the right person to do so the process is listed below:\n1)  Restriction Enzymes break apart several parts of your DNA\n2) All the DNA sequences are put into a microfilament inside a gel.\n3) The gel is attached to an anode and a cathode at one end.\n4) the heavier and more electronexgative pieces move to the anode.\n5) this gives you a unique fingerprinting of your dna. The end result is a bunch of lines on gel which is unique to yourself.\n\nIf you want to get the sequences of your DNA figured out the project is much more complicated and would take many many years. However, the human genome project did it. And since every person has a 1% difference in their alleles (that is right ONLY ONE PERCENT!) it is very similar. Moreover out of 1000 nucleotide bases in a sequence of a polypeptide or DNA, 999 are the same as any other given person. So essentially the human genome project maps your genome very very closely.

Stain with ethidium bromide (careful, its a carcinogen) and photograph under uv light.\n\nMeasure the migration of the bands and those of the size reference.  Plot the migration of the size reference on semi-log paper and use the resulting curve to detemine the size of your plasmid fragments.

none all fingerprints are unique

If the DNA samples applied to the autoradiogram come from both parents and the child, try comparing the distance traveled child's DNA fragments to that of both the mother and father.  There should be commonality to some degree if there is a relationship.  The more markers in common, the more likely the sire.

Hi, here are some good websites that explain these methods better than I could:\nhttp://www.dbbm.fiocruz.br/james/GlossaryB.html \n(short definition of bootstrapping)\nhttp://virgil.ruc.dk/kurser/Sekvens/bootstr.htm\nhttp://gogarten.uconn.edu/mcb221/class30.html\n\n+++++++++++++++++++++++++++++++++++++++++++++++\nhttp://www.dbbm.fiocruz.br/james/GlossaryM.html (short definition of maximum likelihood)\nhttp://statgen.iop.kcl.ac.uk/bgim/mle/sslike_1.html (explanations)\n\nBoth are used for phylogenetic analysis. Maximum likelihood is one of the criteria for inferring phylogenetic relationships, based on a given model of evolution. It's used for protein or DNA sequence characters. \n\nJacknifing is used to evaluate equally parsimonious phylogenetic trees; basically it involves repeated random resamplings of data to see if the resulting trees are reliable.

Simply:\nTake sample cells from your body where a mutation is expected, and from a normal site.\n\nUse an enzyme to dissolve the cell's membrane\n\nUse alcohols to separate the DNA from the solution.\n\nTake the solution and use PCR (Polymerase Chain Reaction) to technically clone the DNA (make copies of it), but add in both normal and abnormal nucleotides (For both the mutated and non-mutated)\n\nPut it in a gel electrophoresis chamber and run electricity through the solution.\n\nYou can actually separate the abnormal nucleotides into specific chambers (A C G T )\n\nThe DNA fragments will separate throughout the gel and will create a pattern which shows the order of the nucleotides so you can find the specific code for the DNA.\n\nCompare the suspected mutated one to the normal cell.\n\n(It's pretty complex but that's the simple version)

any biological item has DNA,hair,saliva,blood- doesnt take much to capture a dna sample

You have to send in a sample.  You wouldn't have to travel personally to a lab.  I'm assuming you mean some sort of DNA fingerprinting profile.  We're a long way from mail-in complete genomes.

The best way to trace maternal ancestry is through Mitochondrial DNA. It is only passed down throught the mother and therefore much less intergrated than "normal" DNA.\n\nThey have used this technique to find the origins of the first "Eve" as it were. So its definitely possible.

First collagen is a protein, so DNA can not be from collagen.  It could be from hair samples.  There is a technique called small pool PCR which allows you to make a 'pool' containing only one genome equivalent, and use that pool for PCR amplification.  That is how you separate out the individual samples.  You would then do 'DNA fingerprinting' using SNPs or microsatellite markers.  PCR would help separate human from non-human DNA, but it wouldn't help if teh DNA sample contains multiple people; and amplification of that sample would be complex and contaminated.  You'd have to separate out the DNA somehow, either by small pool or by cloning.

DNA comparison by electrophoresis. I've seen kits available in school divisions for science classes. On a similar note: paper chromatography to check if the composition of ink between samples are same or different.

1986-In the first use of DNA to solve a crime, Jeffreys used DNA profiling to identify Colin Pitchfork as the murderer of two young girls in the English Midlands. Significantly, in the course of the investigation, DNA was first used to exonerate an innocent suspect.\n\n1987-DNA profiling was introduced for the first time in a U.S. criminal court. Based on RFLP analysis performed by Lifecodes, Tommy Lee Andrews was convicted of a series of sexual assaults in Orlando, Florida.\n\nhope this helps
