Does DNA have anything like IF-statements, GOTO-jumps, or WHILE loops?
In software development, these constructs have the following functions:
- IF-statements: An IF statement executes the code in a subsequent code block if some specific condition is met.
- WHILE-loops: The code in a subsequent code block is executes as many times as specified, or as long as a specific condition is met.
- Function calls: The code temporarily bypasses the subsequent code block, executing instead some other code block. After execution of the other code block the code returns (sometimes with some value) and continues the execution of the subsequent block.
- GOTO-statements: The code bypasses the subsequent code block, jumping instead directly to some other block.
Are constructs similar to these present in DNA? If yes, how are they implemented and what are they called?
