Refer to the figure below, and then answer the question that follows.

-More than one restriction enzyme can be used to cut a piece of DNA at a time.If you used the restriction enzyme BamHI,which recognizes the sequence GGATCC (shown in the figure),as well as another enzyme that recognizes the sequence AATT,how many DNA fragments would be produced from the DNA strand shown?

Quizplus · Accepted Answer

The DNA strand shown must have multiple occurrences of the sequences GGATCC and AATT for the enzymes BamHI and the other enzyme to cut. Since BamHI recognizes GGATCC and the other enzyme recognizes AATT, the presence of these sequences multiple times would result in multiple cuts. Without seeing the actual DNA sequence provided in the question, the correct answer involves understanding that more than one restriction site for each enzyme would result in more than four fragments, leading to the selection of five fragments as the most likely outcome based on the information given.
