if someone lied about age, then was tested, could age be detected

Surprisingly, the answer is a possible 'yes'. At the end of each DNA stand is a group of repeating nucleotides known as 'telomeres'. When the DNA is transcribed sections of the telomeres are lost. Thus, it may be possible to predict someones age by determining how long the telomeres are. I say may because right now it isn't an exact science, but it wasn't all that long ago that we figured out how to determine a baby's father by their DNA.

Prions that protect the ends of dna strands are eroded through the course of your life so it would be possible to detect this which would give some indication of age however other factors such as smoking can cause similar damage. This is why cancer is more common the older you get as the dna has less protection from free radicles, it also means that if you clone an animal all the clones cells will actually be the same age as the original donor and the clone will be as suceptible to age related diseases as the donor even though it is new born.

Everything is possible, i don't know if it ever were tested, but i think in the future or maybe even now people can determine someone's age by DNA test. I would reckon that it is possible, but it has never been proved.

Yes in a way,but its not really done yet, but the teleomeares are cut down each time....and i guess witha few math problems you could.
How do ikno this? well its all over the news, the basic facts are
Aging is caused by Telomerase shortening

No. DNA doesn't show age, just the chromosomes that make up a person, or being.

you cannot determin age with DNA although as you become older the DNA becomes weaker and effectively starts to "come undone"

dna contains codes for protein synthesis. they dont vary with age. so, age determination wud not be possible.

not from dna,your dna is the same your whole life
