The exonuclease FEN1 removes the RNA primers of Okazaki fragments. The complex of DNA polymerase d and FEN1 carries out the same type of nick translation that E. coli DNA polymerase I carries out during Okazaki fragment maturation

When equal amounts of extrorotatory and levorotatory isomers are present, the resulting mixture becomes optically inactive because the optical activities of each isomer cancel each other.

Such a mixture is called a racemic or dl-mixture or (±)-conglomerate and this process of converting an optically active compound into the racemic modification is known of racemization.
