1. A method for expressing at least one polypeptide of interest in a host cell, the method comprising:
- a. introducing a set of genetic elements in a host cell, the set of genetic elements comprising at least one regulatory sequence and at least one coding nucleic acid sequence of interest, wherein the set of genetic elements comprises recombination sites therebetween;
b. exposing the cell under conditions promoting recombination;
c. rearranging the set of genetic elements by allowing recombination between recombination sites; and
d. selecting the host cell having expressing the at least one polypeptide of interest.

Abstract
Methods and compositions are provided for manipulating the genome of host cell to produce at least one exogenous gene product. Also provided are methods and composition for producing a programmable cell comprising a plurality of exogenous genes, wherein each exogenous gene is under the control of a disrupted regulatory sequence and wherein the disrupted regulatory sequences are restored by in vivo recombination. Preferably, the gene of interest is under the control of a genetically altered promoter which sequence recombination effects the expression of the exogenous gene(s).
