These entities were proven to exist in their names
These entities were proven to exist in their namesake's "pulse chase" experiment. Their creation depends on specialized flap endonucleases and RNAse H (R-N-aze H), which remove a primer and pave the way for DNA polymerase omega. These occur in the five-prime to three-prime direction on the lagging strand, and are linked by DNA ligase. For 10 points, name these short segments of DNA created during DNA replication, named for a Japanese scientist.
