Hi Monks,
I would like to place "-" into string A based on the position they are in string B.
Basic Idea: ABABA goes to AB--A-BA based on template BB--B-BB
I can do this just by looping over the two strings, as below, but I am wondering if there is a neat perl way of doing it with out using loops? Thanks for your guidance! 
  my $j =0;
        for($i=0;$i<length($protein);$i++){
        my $chr=substr($protein,$i,1);
                if($chr ne "-"){
                        $new_dna=$new_dna.substr($dna,$j,1);
                        $j=$j+1;
                }else{
                        $new_dna=$new_dna."-";
                } 
                                                                      
+                                                                     
+                                                                     
+                                  }
