Jakarta, In some particular cases such as criminal forensic DNA sometimes required examination of the victim. Actually is there a difference between the examination of DNA forensic DNA tests are normal?
"Actually, just the same as regular DNA testing, forensic DNA testing but usually if the case will be brought to court so that the force of law," says Dr. Herath Sudoyo, MD, PhD as senior researcher at the Eijkman Molecular Biological Institute on the sidelines talkshow Loreal Indonesia Fellowship For Women In Science 2011 in the House Higher Education, Jakarta, Monday (06/20/2011).
DNA or Deoxyribo Nucleic Acid is a nucleic acid that stores all information about genetics. DNA is what determines the type of hair, skin color and specific qualities of human beings.
DR Herath said DNA testing could be done for paternity checks, criminal or immigration (eg a country would not accept a person's entry if it was not his family).
"Which is used for DNA testing is part of the body of people who want to be tested and also for comparison," said researcher who received his PhD from the Monas University, Melbourne Australia 1990.
Generally, the body that is easier to do the examination is blood or cheek mucosa graft, whereas if you use the hair but can also have a higher difficulty level.
If using a blood sample is then taken and white blood cells instead of red blood cells. This is because red blood cells have no cell nucleus which is the most accurate test because the cell nucleus can not be changed.
The specimen is then extracted its DNA before it is processed by a variety of molecular techniques to identify the genomic characteristics of the locations have been determined.
The method used in DNA testing is to identify fragments of DNA itself. Or it simply is a method to identify, collect and inventory the files are typical characters of the body.
DR Herath revealed to non-priority cases took over 12 days to get results because it gives time for the laboratory to analyze, while for cases with priority as is the case then the result could bomb out within 1 day.
"Declared fit if the person's DNA with the DNA match 99.99 percent of the comparison, which is seen here is the structure of DNA is its TGCA," says Dr. Herath.

While a lot of DNA contains information for a certain function, there is some called junk DNA, which is currently used for human identification. At some special locations in the junk DNA, predictable inheritance patterns were found to be useful in determining biological relationships.
