The length of the priming RNA is limited to eight to 14 bases. Apparently, DNA polymerase III is responsible for displacing the primase.

Loss of the zeta population 

Epidermal cell types do not fully regenerate in the absence of zeta neoblasts, the remaining neoblasts (likely sigma) and their derived cell types are unaffected.
