When cells are placed under stressful conditions, they have the capacity to recycle macromolecules for use as nutrients in a process of lysosomal degradation.

The DnaG primase is an RNA polymerase is smaller than RNA Polymerase; and synthesizes short stretches of RNA that are used as primers for DNA synthesis.

DnaG primase associates transiently with the replication complex, and typically synthesizes a 10-base primer. Primers start with the sequence pppAG positioned opposite the sequence 3’–GTC-5’ in the template.

There are two types of priming reaction in E. coli: The oriC system, named for the bacterial origin, basically involves the association of the DnaG primase with the protein

complex at the replication fork.
