The SOS system repairs DNA that has gaps, breaks, and other lesions by
A. cutting DNA from other parts of the genome and pasting it into the gaps or damaged areas.
B. stabilizing single-stranded DNA until the next round of normal replication.
C. using specialized DNA polymerases that will synthesize a new DNA strand even if there is not a normal complementary DNA strand to act as a template.
D. using available mRNA and a special RNA-dependent DNA polymerase to fill in the gaps and replace damaged DNA.
