Bacteriophage-based transgenic fish for mutation detection
First Claim
1. A transgenic fish whose genomic DNA comprises a recoverable assayable mutation target nucleic acid sequence operably linked to a bacteriophage lambda-derived transgene construct;
- wherein the mutation target nucleic acid sequence is recoverable from the transgenic fish, transferable into a bacterial host, and assayable in the bacterial host for the presence of a mutation.

Abstract
The present invention provides transgenic fish whose somatic and germ cells contain a genomically integrated bacteriophage lambda-derived transgene construct. The transgene construct can include an excisable test nucleic acid sequence containing a heterologous mutation target nucleic acid sequence that is detectable via bioassay in a bacterial cell into which the test nucleic acid has been introduced. The frequency of mutations in the mutation target nucleic acid sequence following exposure of the transgenic fish to one or more potentially mutagenic agents can thus be evaluated.
