Here's a breakdown:
* Introns: Non-coding regions within a gene that are removed during RNA processing. They are transcribed into the initial RNA molecule but are spliced out before the mature mRNA is translated into protein.
* Exons: Coding regions within a gene that are joined together to form the final mRNA molecule. They contain the genetic information that will be translated into protein.
Think of it like this:
* Gene: A whole recipe for a cake.
* Introns: Instructions for the cake mold, which are not needed for baking the cake itself.
* Exons: Instructions for the ingredients and baking process, which are necessary to create the cake.
RNA processing involves removing the introns and joining the exons together, producing a mature mRNA molecule that can be translated into protein.
