The Gre factors/TF11S enable the polymerase to cleave a few ribonucleotides from the 3' terminus of the RNA product, thereby allowing the catalytic site of RNA polymerase to be realigned with the 3' -OH.

Malaria (Parasitic)

Sporozoites enter the bloodstream by mosquito.

The sporozoites migrate to the liver, where they multiply, transforming liver hepatocytes into giant multinucleate schizonts, which release thousands of merozoites into the bloodstream.
