Answer 1

To keep it short:

DNA contains instructions to make proteins. RNA carries these instructions to the protein factories (called “ribosomes”). DNA is in the famous shape of a double-helix. Imagine only one side/one half of that – and you have the shape of RNA, which is a single strand.

And all this happens at a micro-cellular level.
