I almost defined all the variables. Would you kindly provide some remedy to
this……
Define all the variables. Or, at least, all of the ones used around line 31.
my ($newbase)=randomnucleotide();
substr($DNA,$position,1,$newbase);
This looks to be around line 31. What does randomnucleotide() return?
sub randomnucleotide {
my ($nucleotides) = ('A','G','C','T');
That doesn't look right.
return randomelement(@nucleotide);
}
How come that's using @nucleotide but the other one is $nucleotides?
Hope this helps!
