![]() ![]() One approach in constructing a restriction map of a DNA molecule is to sequence the whole molecule and to run the sequence through a computer program that will find the recognition sites that are present for every restriction enzyme known.īefore sequencing was automated, it would have been prohibitively expensive to sequence an entire DNA strand. There are other ways of mapping features on DNA for longer length DNA molecules, such as mapping by transduction. In molecular biology, restriction maps are used as a reference to engineer plasmids or other relatively short pieces of DNA, and sometimes for longer genomic DNA. Restriction mapping requires the use of restriction enzymes. ( October 2016) ( Learn how and when to remove this template message)Ī restriction map is a map of known restriction sites within a sequence of DNA. Please help improve this article if you can.
