  • Q:

    Under a high amount of mutagen exposure, the SOS mechanism of replication in prokaryotes forces reproduction past the normal mitotic checkpoints regardless of mutations. Which of the following is a likely fate of the daughter cells derived from E. coli in an SOS reproduction mode?

     

    A

    viability of only a single daughter cell due to isolation of mutated genes in one daughter cell

    B

    no noticeable differences because the checkpoints were all passed

    C

    a survival advantage due to gain-of-function mutations

    D

    death due to high mutation rate in gene products
