Multiple Choice
Which of the following is true about bacterial DNA replication?
A
It requires RNA polymerase to initiate the process.
B
It begins at a single origin of replication.
C
It occurs in the nucleus of the cell.
D
It proceeds in a unidirectional manner.
Verified step by step guidance
1
Understand that bacterial DNA replication is a process by which bacteria duplicate their genetic material before cell division.
Recognize that bacterial DNA replication begins at a single origin of replication, which is a specific sequence in the DNA where replication starts.
Note that bacterial cells do not have a nucleus; instead, their DNA is located in the nucleoid region, so replication does not occur in a nucleus.
Realize that bacterial DNA replication proceeds in a bidirectional manner, meaning it moves outward in two directions from the origin of replication.
Clarify that RNA polymerase is not required to initiate DNA replication; instead, DNA replication is initiated by a group of proteins including helicase and primase.
