Search for motifs in DNA or protein
-
Interact with users at the keyboard
-
Write data to files
-
Use loops
-
Use basic regular expressions
-
Take different actions depending on the outcome of conditional tests
-
Examine sequence data in detail by operating on strings and arrays
These topics, in addition to what you learned in Chapter 4, will give you the skills necessary to begin
