In my biology class, we’re learning about gene regulation/expression and transcription of a gene.
I sort of understood what gene regulation is, but I still don’t understand the steps that go with the process and what transcription is along with what is the purpose of that. I also don’t understand the clear difference between needing mRNA to be synthesized through DNA?
I appreciate your help.

The overall purpose of DNA is that it is many times more stable than RNA, which allows for more complex organisms.
The double strand of the DNA structure means that when a nucleic acid is damaged then the whole structure is compromised and it can be repaired or destroyed before it goes on to encode a protein that may be ineffective or harmful.
When it comes time to actually create a protein for your body though DNA is far too massive. It contains instructions for every single protein in your body. So a small piece of DNA is copied onto a strand of RNA and that RNA strand will contain only the instructions for the specific protein that needs to be made.
Think of DNA as a physical cookbook that contains 200,000 recipes. The book is way to big to move around but there are many cooks that need that information to do their jobs. RNA is a copy of a single recipe that is delivered to the cook who needs the information.
