DOES DNA HAVE THE EQUIVALENT OF IF-STATEMENTS, WHILE LOOPS, OR FUNCTION CALLS? HOW ABOUT GOTO?

Summary from the TLDR newsletter

While DNA is not analogous to computer code, biological systems have some pathways that operate in similar ways to computers. 'If' statements are similar to transcriptional activators, transcriptional repressors can act as 'while' statements, and there are codes that make other sections dispensable, kind of like a GOTO statement. There are no equivalents of function calls as all events happen in the same space and there is always a likelihood of interference.
