character dropped. 
StringDrop
StringDrop["string",n]
gives "string" with its first n characters dropped.
StringDrop["string",-n]
gives "string" with its last n characters dropped.
StringDrop["string",{n}]
gives "string" with its n
character dropped.
StringDrop["string",{m,n}]
gives "string" with characters m through n dropped.
StringDrop[{s1,s2,…},spec]
gives the list of results for each of the si.
Details
- StringDrop["string",UpTo[n]] removes n characters, or as many as are available.
- StringDrop["string",{m,n,s}] drops characters m through n in steps of s.
- StringDrop uses the standard Wolfram Language sequence specification.
- StringDrop[BioSequence["type","seq"],spec] applies the operation to the string "seq", yielding a biomolecular sequence.
- Given a circular BioSequence and a starting position greater than the ending position, i.e. m>n, then StringDrop[bioseq,{m,n}] drops the wrapped-around sequence starting at m and ending at n.

Newline (\n) counts as a single character:
StringDrop works like applying Drop to the list of characters:
StringReplacePart with an empty string can be used like StringDrop:
StringReplacePart can drop several sequences of characters at a time:
