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.
