DNA has a halflife of 521 years. That means that in 521 years, half of the DNA that you passed down through your children has decayed. At this rate, in 6 million years, your decendants will be void of your decay..decays... but is that true?
Not exactly. DNA which is sitting out will decay. but let's not forget our descendants come from DNA which is, at most, half being no more than 60 years old (but probably at most 30) and the other half at most being likely less than one day old.
Now, you have personal experience in the creation of descendants and us men over here have personal experience in the fresh manufacture of DNA. Mow, you have told us you were pregnant at 14. That means that you had two components: eggs that were created when you were in your mother's womb, which means that set of DNA was about 14 1/2 years old (unless I'm wrong, my understanding is a woman gets her lifetime supply of eggs while she is a fetus.) Now, when you mated with your boyfriend, at the moment of his orgasm he ejaculated ~500,000,000 fresh sperm into you that his testicles had manufactured probably no more than a couple of hours earlier, meaning that set of DNA was less than three hours old. Thus at any time you or any woman becomes pregnant through the usual and customary fashion, her fetus started out with half its DNA being very fresh from the father, and the other half being about 6 months older than her. (For non-usual and customary methods like frozen eggs or in vitro fertilization, then it's no older than the maximum time of viable storage plus the older of the eggs or the sperm.)
What is DNA? It is a set of four chemicals arranged in certain combinations, that in 5%-10% of what is there, provide the instructions to produce a living organism. (90-95% of DNA is believed to be "junk" DNA; DNA that either has no (known) function, or its function is disabled (turned off).)
So, realize that the DNA of living entities are the copy of that came from its parent (for entities that use cloning or pathogenesis for reproduction) or 1/2 of the DHA of each of its parents (for two-parent entities) or proportional amounts for any that have three or more parents, plus, for all entities, changes that come from copying errors such as environmental problems like the environment being hostile like too acidic or too alkaline, or gets mutated trhough cosmic rays. This means the DNA at the time of conception is no older than the oldest of their parent(s).
So while DNA as a chemical becomes 1/2 degraded in 521 years, the DNA in entities still alive remains fresh because the entity grows and rebuilds its cells on a constant basis. But that's not completely true because cosmic rays cause mutations, creating tiny changes in its DNA.
