DEFINITION

Classification: 435/463

Involving general or homologous recombination (e.g., gene targeting, etc.):

(under subclass 455) Processes wherein one or more segments of nucleic acid of sufficient length and similarity to target said nucleic acid to a region or regions of DNA in the cell are present on the nucleic acid molecule and wherein the segment or segments direct homologous recombination into said region or regions in the cell by means of the general recombination mechanism of the cell.

(1) Note. Not proper for this subclass are methods wherein a recombination event occurs in site-specific fashion, directed by a specific enzyme or other specific catalytic agent. Also excluded are random integration methods which are classified instead according to other elements of the invention.

462, for recombination events occurring in site-specific fashion, directed by a specific enzyme or other specific catalytic agent.
