Which of the following statement is true with regards to the bacterial DNA polymerases III and I? Both DNA pol III and DNA pol I exhibit 3 'to 5' polymerase activity DNA pol III exhibits 3' to 5' exonuclease activity while DNA pol I exhibits 5'to 3' exonuclease activity DNA pol III is responsible for removing RNA primers only in the leading daughter strand DNA pol III replaces RNA primers with DNA in both the leading and lagging strands Two of the choices are correct

Which statement is TRUE? During the replication of bacterial chromosomes: DNA pol III is responsible for the majority of DNA synthesis on both the leading and lagging strands. DnaA makes the primers necessary for continuing synthesis by DNA polymerase (DNA pol). DNA polymerase (DNA pol) moves along the template strand in the 5' → 3' direction. DNA helicase removes primers from a replication fork, allowing DNA pol to read the template strand during synthesis. initiation at oriC requires the Tus protein to bind to specific sequences, creating ssDNA for assembly of replisomes.

What comparison between DNA and RNA polymerase is NOT true? A. DNA pol catalyzes the addition of deoxyribonucleotides, RNA adds ribonucleotides B. Both DNA pol and RNA pol synthesize in the 5' to 3' direction C. RNA pol makes more mistakes than DNA pol D. DNA pol temporarily displaces (opens) the DNA strand, RNA pol does not E. RNA pol does not need an RNA primer to initiate transcription, DNA pol does need a primer
