Linking retroelements to autoimmunity.

abstract：:A model of hematopoietic development wherein multipotentiality is conserved until segregation of myeloid and lymphoid potential has recently been challenged, proposing that megakaryocyte/erythrocyte (MegE) potential is lost in Flk2/Flt3-expressing early progenitors.

abstract：:The E. coli replication fork synthesizes DNA at the rate of nearly 1000 nt/s. We show here that an interaction between the tau subunit of the replicative polymerase (the DNA polymerase III holoenzyme) and the replication fork DNA helicase (DnaB) is required to mediate this high rate of replication fork movement.
