The GHC API requires writing the code evaluation model from scratch. This is a complicated task. iHaskell reimplements a lot of GHCi directives (so notebooks can be GHCi compatible) but doesn’t cover a lot of useful ones e.g :set package and :script. For this reason, Sabela evaluates the code with a cabal subprocess. This ensures that you get all of GHCi’s API for free.
In 1977, Sanger developed a much simpler sequencing method, called “chain termination,” which is today known simply as Sanger sequencing. This technique took advantage of a different type of special nucleotide called a dideoxyribonucleotide, or ddNTP. ddNTPs lack one of the hydroxyl groups present on a normal dNTP, preventing the chemical reaction necessary to add another nucleotide and terminating DNA elongation.
