RE: User problem

The expression
Table[Random[Integer, {1, 4}], {Random[Integer, {240, 250}]}]
works fine for me. (Win 98 on a compaq 1200 notebook).
You probably get into troubles while using a symbol (i) appearing twice,
once as a counter for Table, and once for nothing really necessary.
If you want to be able to specify the length of your list, you can use
genome[i_Integer]:=Table[Random[Integer,{1,4}],{i}]
