NOTE:
(1) For each submission, each DNA sequence must start with a greater-than symbol (">") in the first column. The words right after the ">" symbol in the single initial line are optional and only used for the purpose of identification and description.

(2) If a query sequence contains any illegal character, the computation will be stopped by prompting a warning message.
