DNA modifying enzymes that recognise specific motifs of double stranded DNA and cleave it into fragments of different lengths type II restriction enzyme: recognises a specific palindrome sequence motif (GAATTC) sequence motif with an axis of rotational symmetry, the sequence in 5`  3`-direction is equal on the both strands small rings of double stranded extrachromosomal and independently reproduced DNA, natural types are important for antibiotic resistance and sexual reproduction of bacteria vehicle of genetic engineering shuttle that allows reintroducing of foreign DNA into a host organism Endonucleases Palindrome Plasmids EcoRI Vector

bacterial plasmids with features for reintroducing of small foreign DNA-fragments into host organisms with the purpose of producing significant amounts of recombinant DNA Cloning vector diagram showing sites of cleavage of a DNA molecule, for example of a plasmid vector Restriction map Cleavage of DNA with this type of endonucleases creates a short complementary single stranded overhang in each cleaved end Sticky end enzymes Blunt end enzymes Endonucleases that form no 5’ or 3’ overhangs after cleavage Competent cells Bacterial cells which are able to incorporate foreign DNA

lac-Operon Bacterial expression unit of genes for lactose utilisation Agarose gel electrophoresis Method that separates DNA fragments in an electric field as a function of their lengths Polylinker Staged recognition sites of different restriction enzymes, a feature of vectors for variable insertion of foreign DNA Isoschizomer Restriction enzymes that recognise the same target sequence Ethidium bromide (EtBr) Stain that intercalates into double-stranded DNA. Under UV-light the complex of DNA and the stain fluoresces pink
