This is the final installment of a lil' programming trilogy; I decided to write code for a Turing machine that can transcribe DNA to mRNA, and then wrote a similar but less capable version in Python (since I'm just starting out). Now, it's come to Scratch! This is also my first foray into lists, so yay for that.
If you don't know, DNA to mRNA transcription is the first key process of protein synthesis, and it occurs in the nucleus. DNA is split into two and enzymes read one strand, then assemble a second strand of mRNA to match it. This project copies that process and allows you to quickly and easily transcribe DNA like the cells in your body right now. Here's a link to the Amoeba Sisters' video on protein synthesis: https://www.youtube.com/watch?v=oefAI2x2CQM&vl=en
