Final answer:
One bacterial DNA polymerase undertakes semiconservative replication, resulting in the daughter DNA molecules containing both parental and newly synthesized strands.
Step-by-step explanation:
One bacterial DNA polymerase undertakes semiconservative replication. The others are involved in other reactions.
In DNA replication, the process is semiconservative, where each daughter DNA molecule contains one parental strand and one newly synthesized strand.
In bacteria, the initiation of replication occurs at the origin of replication, where the DNA is unwound, made single-stranded, and a short RNA primer is synthesized by primase. DNA polymerase III then adds DNA nucleotides to the primer, resulting in the synthesis of the daughter DNA strands.
