we analyzed the effects of additional mutations that inactivate dna replication proteins ( genes 32 and 43 ) , an rna polymerase-binding protein ( gene 55 ) , type ii topoisomerase ( gene 52 ) , and an exonuclease function involved in recombination ( gene 46 ) on the synthesis of plasmid-coded gp23 in relation to chromosome-coded t4 late proteins .
