One is unequal crossing over, in which recombination happens between different positions on chromosomes that are misaligned during meiosis. 

Another is replication slippage, in which the DNA polymerase loses its place and copies a segment of chromosome twice.

E. coli SSB- Note that this protein is not a DNA-unwinding protein; its function is to stabilize DNA that is already in the single-stranded condition

ssb mutants have a quick stop phenotype, and are defective in repair and recombination as well as in replication.

All DNA polymerases require a 3'-0H priming end to initiate DNA synthesis.

The priming end can be provided by an RNA primer, a nick in DNA, or a priming protein.

For DNA replication, a special RNA polymerase called a primase synthesizes an RNA chain that provides the priming end.
