Rd genome is the first genome of a free living organism to be completed. It is significant in that it is the strain from which the first DNA restriction enzymes were purified. The genome is shown here as a circular representation. It is 1.83 Mb in size and contains approximately 1740 open reading frames. Nucleotide 1 was defined by a unique Not I restriction endonuclease site.
Restriction mapping is essential for accurate lab work.
The GCG program MAP easily chews through DNA sequences giving you a very nice restriction map of your sequence.
