For in-silico tool, I would like to classify coding and non-coding regions of gene.So can anybody kindly explain the the properties of these two regions for classification?
Very bfiefly (like Mr Putin likes to say :) ). If you count a triplet frequency dictionary so that the triplets are tiled with no gaps, but with no overlapping, for coding and non-coding area, then such triplet frequency dictionaries differs significatnly to distinguish he coding from non-coding parts. Meanwhile, quite a lot depends on specific issues of the task...
You might want to capitalize from the paper attached, and from few more references:
