How to identify the cis-elements in genomic DNA? also how to script a simple code in C/perl to do the same.?

to identify, one should look for physical or chemical traits of cis-elements in genomic DNA.


please do mention how the cis-elements can be identified in a strand of genomic DNA.


the code should take in a sample DNA strand as the input and identify and give the cis-element in that as the output. the code can be in either C or perl or any programing language.

Your description of the methodology sounds correct, but I do not have any code that would search for only cis-elements.
