RNA secondary structure Updated 2025-07-16
Analogous problem to the secondary structure of proteins. Likely a bit simpler due to the strong tendency for complementary pairs to bind.
Type of RNA Updated 2025-07-16
The most important ones are:
Integrase Updated 2025-07-16
Reverse transcriptase Updated 2025-07-16
Converts RNA to DNA, i.e. the inverse of transcription. Found in viruses such as Retrovirus, which includes e.g. HIV.

By GitHub around Black Lives Matter, due to a possible ludicrous relationship with slavery of black people:For the love of God, the word "master" is much more general than black slavery. If you are going to ban it, you might as well ban the word "evil".
Several software projects followed the purge from their codebases, maybe GitHub followed someone else's lead, it's hard to say.
The words "whitelist" and "blacklist" were also targeted.

R (complexity) Updated 2025-07-16
Set of all decision problems solvable by a Turing machine, i.e. that decide if a string belongs to a recursive language.
Undecidable problem Updated 2025-07-16
Is a decision problem of determining if something belongs to a non-recursive language.
Or in other words: there is no Turing machine that always halts for every input with the yes/no output.
Every undecidable problem must obviously have an infinite number of "possibilities of stuff you can try": if there is only a finite number, then you can brute-force it.
