A composite part that can detect the recA.

Introduction

The SOS response is a global response to DNA damage in which the cell cycle is arrested and DNA repair and mutagenesis are induced. The system involves the RecA protein (Rad51 in eukaryotes). The RecA protein, stimulated by single-stranded DNA, is involved in the inactivation of the LexA repressor thereby inducing the response. It is an error-prone repair system that is attributed to mutagenesis.

The toxins will cause DNA damage, making DNA become single-strand DNA(ssDNA), which can activate protein RecA. So, what can protein RecA do? E.coli has a sos response system, and there is a repressor LexA which inhibits the next reaction, so the fluorescent gene won’t express. But when the a ctivated protein RecA comes and hydrolysis the repressor LexA, the next reaction ca n work, so the fluorescent gene will express. Therefore, we can know that there is Aflat oxin in the oil we test. These are all about our treatment group.
