Next, we will take a drop of DNA from each whale and put it in a special plate and send it to our collaborator at Oregon State. His team will then perform a related technique that will provide a DNA fingerprint for each whale. This information will identify each whale uniquely and show familial relationships. Then we may be able to separate our whales into families and see if we sampled any whales twice. The DNA extractions started today so that work is in process. In addition, James continues his work on chemical dispersant toxicity in human cells, while Cathy ramps up her efforts of [more...]

How Fingerprinting Helps In DNA Paternity Testing

This form of fingerprinting method is also known as DNA profiling. Using this technique, the individuals are identified on the basis of their unique DNA profiles. This DNA profiling is done by analyzing the VNTR sequences. It stands for variable number tandem repeats. This sequence is found to be different in individuals except in twins. As per the facts mentioned above, the DNA samples of the child will exhibit the similar VNTR loci as that of their parents. This fingerprinting helps in identifying that whether the known father of a child is genuinely his biological dad. In fact, it is [more...]

Despite the fact that the assailants broke into the wrong home, they decided to rob the elderly woman. During the robbery they tied up the woman and taped her mouth shut. Detectives were able to locate a fingerprint on a the piece of scotch tape located at the crime scene that matched the defendant's fingerprints. The third case against the defendant was a kidnapping charge that allegedly occurred when the defendant held a pawn shop owner hostage in his home for over 9 hours. The defendant and his accomplices beat the victim for hours in an effort to secure the pass codes to get into his [more...]

Browse > Home / Technology / New forensic test can match suspects’ DNA with crime samples in 4 hours (ChattahBox) – As we have seen even in high profile cases, getting confirmation on a DNA hit can take a very long time. But a newly developed test could make checking DNA from people arrested for crimes with DNA samples from crime scenes stored in forensic databases almost as easy as matching fingerprints. With the test, police could check on whether a person’s DNA matches that found at past crime scenes while suspects are still being processed and before a decision on whether to [more...]

DNA fingerprinting simplified

One of the most frequently used tools in biochemistry and biotechnology, agarose gel electrophoresis is a common forensic technique often used in genetic or DNA fingerprinting. The procedure is achieved by moving negatively charged nucleic acid molecules through a gelatinous substance known as agarose by using an electric field. Andrew, in collaboration with his father and other researchers, completed the study, which is published in the January 2008 issue the American Society of Horticultural Science’s journal HortTechnology. The youngest author ever to publish in an ASHS journal, Andrew [more...]

DNA Testing- The Process_9585

DNA testing, accordingly, is the scientific process and technique employed to competently identify individuals through their respective DNA features. This is also known in this field by other terms, such as DNA profiling, DNA typing,Nike TN Requin, or genetic fingerprinting. DNA profiles are encrypted sets of numbers that reflect the genetic makeup of a person. This can be used to identify and verify that person accurately. In this technique,mercurial glide, it uses repeat sequences which scientists describe as highly variable. These are what are known technically in this field as the [more...]

Biologists Tackle Cells' Identity Crisis

The group has now developed and tested a standardized procedure for extracting DNA from cells, doing the fingerprinting and interpreting the results.“Without policing, many investigators may not be motivated to do the necessary tests.” Many researchers already use DNA fingerprinting to test their cell lines, notes Steve Oglesbee, director of the tissue-culture facility at the Lineberger Comprehensive Cancer Center of the University of North Carolina in Chapel Hill. The ATCC and other repositories have already established fingerprints for some of the most commonly used lines. "We're [more...]

DNA fingerprinting or (altogether now) the Polymerase Chain ...

In nature, cells make more DNA by undergoing a process known as replication. This is where the amount of DNA is essentially doubled so that a cell dividing into two new cells can give each of these two cells a complete copy of the DNA. However, replication is a relatively complex process (see previous notes on this), requiring the regulated actions of over half a dozen different enzymes – technically challenging to pull off in the laboratory. PCR is therefore an experiment that simplifies the process of replication for greater efficiency in test tube settings. A bit of history :Kary Mullis [more...]

Variants of PCR (1)

The bacteriophage T4 DNA polymerase was also tested shortly after the first reports of PCR. It has a higher fidelity of replication than the Klenow fragment. Since it is also destroyed by heat, it has seen little use since the development of thermostable polymerases. The DNA polymerase from Thermus aquaticus (or Taq), was the first thermostable polymerase used in PCR, and is still the one most commonly used. The enzyme can be isolated from its 'native' bacterial source, or from a cloned gene expressed in E. coli. The Stoffel fragment is produced from a truncated gene for Taq polymerase, [more...]

The DNA Fingerprinting Process

The DNA fingerprinting process was developed in 1985 by the British scientist Alec Jeffreys. At first, DNA fingerprinting was used to establish genetic relationships in paternity and immigration cases. It was first used to secure a conviction of rape in 1987 and is becoming more common in violent crimes, such as assault and battery charges, in which skin, semen or blood is found. Since then, DNA Fingerprinting has been subject to great controversy and scrutiny by the scientific and criminal justice community. Leading scientists have waged battles in the courtroom over the reliability of [more...]

E. Coli Timeline Reporting – Investigation and Oubreak

To find cases in an outbreak of E. coli O157 infections, public health laboratories perform a kind of “DNA fingerprinting” on E. coli O157 laboratory samples. Investigators determine whether the “DNA fingerprint”  or PFGE (pulsed field gel electrophoresis)pattern of E. coli O157 bacteria from one patient is the same as that from other patients in the outbreak and from the contaminated food. Bacteria with the same “DNA fingerprint” are likely to come from the same source.

Rape Kit Examination Leads to Solving Crimes - The Daily Beast

Like many victims, the courageous teen spent the next several hours in a hospital emergency room, where doctors examined her and prepared an evidence collection kit that they knew could supply a forensic link to the stranger who committed the devastating crime. The exams are intrusive and impersonal, too, yet survivors submit to them in hopes that the results will bring a perpetrator to justice. But there were no DNA databanks operative at that time, and no suspect against whom to compare the DNA left on the young woman's body.
