I think opened up a whole new dimension to research to new and cold cases

also....

DNA can tell if the kid is yours ....hahahha !

DNA? Di Nila Alam ...................... sa Pilipinas

How it works? 

well, same question here... how does it work? i only have a slight idea because of my basic chemistry subject in high school. anyone who has gone tru formal education or thorough lecture on this? thanks.

oh i think dna it works you have to have a sample of the parents and the child's blood ,perform  blood compatibility or what they called blood cross matching (its like donating blood hahha i dont think so) is needed in here and if the results matches the dna of parents and child's DNA so that WORKS..means that he or she is their  child.....ewan.....ko kung nasagutan ng tama.....i forgot my serology subject already..we tackle that one time abt DNA ..a test to find  if the kids are yours.......lolz

ei, thanks. there are really lots of amazing things to learn...

I watched SOCO by Gus Abelgas and still they have not shown any cases about DNA testing.

ano ang patakaran ng DNA ngayon sa local crimes? is it admissible in court for exhibits? or just for criminal investigations only?

no comment

We all comment on what DNA is all about without clear understanding of its importance in criminal investigation. Its simply meant that the genes of the parents is transmitted to their offspring hence paternity or maternity is establish without any doubt. Since it is genetic, it is also unique in each individual that he can be identified from anything coming from his body for DNA testing.

attention to all criminal justice educator:

may we request for the offering of DNA matters as one our crim professional subjects so that this matters will be clarified and discussed with the crim students in the classroom.........para hindi naman tayo masyadong huli sa technology ng criminalistics.......[/cente :-*[color=green][/color]r]

hello everyone.. DNA could be discussed in Forensic Chemistry. There is no need to offer it as one of the major or professional subjects in Criminology.

To give you a background:

DNA is deoxyribonucleic acid. It is a kind of chemical that is found in ALL cells of our body (as well as in plants, animals, fungi, and bacteria). Since ALL, it is therefore found in sperm cells (hence, in semen), in saliva, in blood, in body tissues, etc. It is called the blueprint of life because it contains the code (genes) for the production of proteins and other building blocks that will become the parts of our body. It dictates the color of our hair, skin, eyes, etc. It contains the information that is necessary for us to live (and die!). The DNA is unique, no two individuals would have the same set of DNA (even twins, contrary to popular belief that everything is the same between identical twins).

Since no two individuals have the same DNA, it is a good crime-fighting tool. Through the process of DNA fingerprinting or DNA analysis, even a very minute amount of DNA could help trace the source or donor of the sample from where the DNA was obtained. This is done thru the Polymerase Chain Reaction or PCR. What the PCR does is it amplifies (or multiplies or make many copies) the small amount of DNA obtained. It is like making many copies of your 1x1 ID picture and enlarging it. Thermocycler is the machine used in making copies of DNA.

What I can say is...watch where you leave your DNA  ;D

I hope this brief intro on DNA could help you to have a good grasp of the topic. If it does not suffice, you can use the Internet to read more. You can start with <www.genetics.gsk.com/kids/dna01.htm> The topic is presented in a very simple manner (pang kids!) so even those who have no background at all could appreciate DNA.

Good luck!

hahaha! this one' a stagnant thread!

DNA is one good/best tool for personal identification. Problem here is that, only few of us here knows how to make the analysis as well as not having the equipment for the process

Not to mention that DNA analysis is quite expensive!

Those of us who had visited the PNP Crimelab in Camp Crame must have seen the machine used to process DNA examination. And according to Supt(Dr) Supe the process is quite simple to those who have undergone the training. In fact, they have several success stories in proving that DNA analysis results to better administration of justice. Yes, we have trained DNA examiner and have the equipment to do the analyses. Yun nga lang kung minsan nauubusan ng supply.
