1. The small fragment (35 kD) possesses a 5’– 3’ exonucleolytic activity, which excises small groups of nucleotides, up to 10 bases at a time.

2. This activity is coordinated with the synthetic/ proofreading activity. 

3. It provides DNA polymerase I with a unique ability to start replication in vitro at a nick in DNA.

the energy of substrate oxidation (succinate yields fumarate) drives ATP synthesis in mitochondria, we would expect inhibitors of the passage of electrons to O2 (such as cyanide, carbon monoxide, and antimycin A) to block ATP synthesis.
