All the following will not be applicable to DNA replication in prokaryotes except:
1. It begins at several places along the chromosome.
2. It begins at the origin and travels in both directions.
3. It begins at the origin and travels around the chromosome back to the origin.

If a bacterial cell were to contain 4 nucleoids per cell, the number of copies of the bacterial chromosome present in each cell will most likely be:
1. 1
2. 2
3. 3
4. 4

Okazaki fragments during DNA replication

3. Polymerise in 5’ → 3’ direction and explain 3’ → 5’ DNA replication
4. Cause transcription
