If an organism had a DNA polymerase III that lost its ability to proofread,
which of the following statements would be TRUE?
If an organism had a DNA polymerase III that lost its ability to proofread, which of the following statements would be TRUE?
- DNA could not be synthesized, and the organism would die.
- . DNA polymerase III would randomly add new nucleotides, and the entire sequence of new DNA would be worthless. The organism would die.
- The mutation rate for the organism would increase, and more substitutions would be seen in its DNA than in an organism that had functional proofreading. (correct)
- . The proofreading ability of RNA polymerase would restore the lost proofreading ability of the DNA polymerase III, and the organism would be normal.
