Question
Chapter 28, Problem 8P
Summary Introduction
To determine: The effect of mutation in LexA gene that prevents the autocatalytic cleavage of LexA protein.
Introduction:
RecA proteins and LexA repressor are the part of SOS response which regulates the DNA repair mechanism if the DNA is damaged due to exposure of DNA damaging agent. RecA protein binds to the damaged site of DNA and produces self-cleavage of the LexA repressor followed by active gene transcription.

I need help with the following question
For CARS, which statement is not true regarding its advantages?
a) Contrast signal based on vibrational characteristics, no need for fluorescent tagging.
b) Stronger signals than spontaneous Raman.
c) Suffers from fluorescence interference, because CARS signal is at high frequency.
d) Faster, more efficient imaging for real-time analysis.
e) Higher resolution than spontaneous Raman microscopy.
