very confused as to what DNA is, and have no technical expertise to understand detailed articles! Is DNA something you can look at under a microscope or what?

DNA is like a book that every living thing has inside their cells. It’s a book that tells your cells what to do, how to replicate and how to form you. Every living thing has DNA and by using chemicals and expensive lab equipment scientists can pull that “book” out of your cells and read it.
After we die all the materials and cells that make-up our body start to break down and that includes the DNA “book” we have inside. However, sometimes depending on how our bodies were preserved when we died, that book can last a really long time. Bones are not an especially good place to get DNA from but sometimes people can find preserved tissue inside them which you can extract DNA from.
