Yes, DNA does have a shelf life. It has a shelf life of about four years if it is properly preserved.
DNA that left inside and dry at room temperature can last for years, such as that found on hairs in a hair brush. DNA in harsh conditions such as high heat or strong chemicals, can degrade very quickly (minutes to years). DNA that is preserved well can last a very long time - an ancient human from over 4000 years ago was recently discovered with DNA of sufficient quality that it could be sequenced. DNA can stick around forever, as long as it is in the right conditions.
orgns are preserved because other persons will make use of it that's why it's preserved.
He preserved food by pasteurization .
A fossil is any trace of an organism preserved in a rock.

They are going to use DNA from a preserved thylacine fetus.
Yes, it is possible for them to have DNA. But in most cases the part that would have held the DNA will have disintegrated. If hair or skin and other organs are preserved by cold or some other process it is possible to obtain DNA. We have gained knowledge about Dinosaurs and Mammoths through this sort of DNA.
Routine DNA fingerprinting of any person arrested for ANY offence has meant many previously un-solved crimes have been cleared, due to evidence preserved at the scene being matched against the police DNA database.
It's "well-preserved".
Yes. Viable DNA has been preserved withing the animal's teeth and bones. Many studies are being conducted to see if would be possible to clone a mammoth by using modern elephants as segregates.

Rics is totally not preserved! My parents are from Laos and they told me it's not preserved.
Flora preserved jam every year. The mummy was perfectly preserved. I preserved a petal of the rose in my copy of The Scarlet Letter. The preserved skin tissue helped identify the body.
The Australian Museum's head of evolutionary biology, Dr Don Colgan is leading a team of scientists in an attempt to bring the Tasmanian Tiger back from extinction. Dr Colgan led the team in extracting fragments of DNA from the body of a preserved Tasmanian Tiger pup which had been preserved in alcohol 137 years ago. The next step should be to attempt to tease whole chromosomes from the fragmentary bits of DNA salvaged from the preserved pup. Dr Colgan has already stated that this attempt (at its present funding) only has an eight to ten percent chance of success.
embalmers preserved a mummy.
