Provide a Web interface to the functionality provided by the
This program receives two nucleotide sequences from the user and checks
whether they are complementary.
- Create a .html file containing a web form that receives two DNA sequences from the user.
- The form should invoke a .cgi script
(a modification of the comp_seq.pl program) that receives the
form's input, and outputs a nicely formatted HTML page to the user when the form's
submit button is pressed.
Nicely formatted means (at least) that the complementary sequences
should be displayed as either "preformatted"
text (using the <PRE>..</PRE> tags) or as a table.
- The modified program should reject sequences containing characters
other than ACTG as invalid. Remove apaces and digits from the input before sequence validation.
NOTE: Your cgi program must have a .cgi extension.
It (like the .html file containing the form) must reside in your
public_html/cgi-bin directory and they must be readable and executable "by the world".
