KEY CONCEPT Biotechnology relies on cutting DNA at specific places.

Scientists use several techniques to manipulate DNA. Chemicals, computers, and bacteria are used to work with DNA. Scientists use these tools in genetics research and biotechnology.

Restriction enzymes cut DNA. Restriction enzymes act as “molecular scissors.” come from various types of bacteria allow scientists to more easily study and manipulate genes cut DNA at a specific nucleotide sequence called a restriction site

Different restriction enzymes cut DNA in different ways. each enzyme has a different restriction site

some cut straight across and leave “blunt ends” some make staggered cuts and leave “sticky ends”

Restriction maps show the lengths of DNA fragments. Gel electrophoresis is used to separate DNA fragments by size. A DNA sample is cut with restriction enzymes. Electrical current pulls DNA fragments through a gel.

Smaller fragments move faster and travel farther than larger fragments. Fragments of different sizes appear as bands on the gel.

A restriction map shows the lengths of DNA fragments between restriction sites. only indicate size, not DNA sequence useful in genetic engineering used to study mutations
