Surely you know about Rosalind ? It's an online collection of programming problems related to bioscience. Each problem has a pamphlet with biological/genetic background.

There is no online IDE you must use, and no time limit. However, you're asked to paste or upload the output within a few minutes of downloading the randomly generated input dataset, so your solutions must be efficient. Rosalind encourages Python and provides relevant tutorials, but you can use any language you like. Rust, Lua, Javascript, Smalltalk, LISP, Nim, INTERCAL, Bash or Scala - it's up to you.

I have seen Rosland before [0]. It is fun, but the really difficult problems are the ones with tons of biological edge cases. The level of complexity biology throws at you is truly staggering.
