PPT-13.2 – Manipulating DNA

The Smallest Scissors in the World Have you ever used your word processors Search function You can specify a sequence of letters whether it is a sentence a word or nonsense and the program scrolls rapidly through your document finding every occurrence of that sequence How might such a function be helpful to a molecular biologist who needs to search DNA for the right place to divide it into pieces. ®.
