DNA. What is it made of? How does it makes us what we are? How and why do we share the same DNA with animals, plants, fruits, etc. ?

Trying to really simplify here; this is some really big concepts at such a micro-level that most five year olds wouldn’t really ever get it.
So DNA is made up of a sort of code, and each combination of three “letters” of that code translate to a different building block. Your DNA is made of two halves that fit together kind of like a zipper. When it’s time to read that DNA, it gets unzipped, which reveals the code inside. Then those building blocks that go with each three-letter combo line up and fold together to make proteins or hormones or whatever is being made. Then the DNA gets zipped back up until the next time it’s being read.
Most DNA is code for things that a lot of living things share. That’s why a lot of DNA is the same throughout most animals. Every mammal on the planet has blood, for example, and a lot of the parts to make mammal blood cells are very similar, so it makes sense the DNA that codes for those parts is also similar.
