Here's a breakdown:

* DNA (deoxyribonucleic acid) holds the genetic instructions for an organism.

* RNA (ribonucleic acid) is a molecule that helps carry out those instructions.

* Transcription is the process where a specific segment of DNA is used as a template to create a complementary RNA molecule. This RNA molecule will then be used to create a protein.
