What does the bacterial cell cycle involve?

• The formation of new cells through the replication of RNA

• The formation of new cells without the replication of DNA

• The formation of new cells through the replication of DNA and partitioning of cellular components into two daughter cells

• The formation of new cells through the exchange of DNA with other cells

How do prokaryotes reproduce?

• Sexually

• Through spore formation

• Through budding

• Asexually

What is the typical structure of bacterial chromosomes?

• They have multiple linear chromosomes

• They have a single circular chromosome

• They have a single linear chromosome

• They have multiple circular chromosomes

What is the most common mechanism of cell replication in bacteria?

• Mitosis

• Meiosis

• Binary fission

• Budding

What does the cell do before dividing?

• It decreases its number of cellular components.

• It detaches from the inner cell membrane.

• It grows and increases its number of cellular components.

• It replicates its DNA.

Where does the replication of DNA start in bacterial cells?

• At the terminus

• At the origin of replication

• At the cell wall

• At the nuclear membrane

How does replication proceed after it starts?

• In the same direction until the origin is reached again.

• In random directions along the chromosome.

• In opposite directions along the chromosome until the terminus is reached.

• It stops immediately after it starts.

What is the first step in binary fission in bacteria?

• Formation of division septum

• Cell elongation

• DNA replication

• Cell separation

During binary fission in bacteria, what forms in the center of the cell?

• A new nucleus

• A division septum

• A cell membrane

• A spindle fiber

What do the two daughter cells receive after a binary fission event?

• A copy of the original cell membrane

• A copy of the original ribosomes

• A copy of the original chromosome

• A copy of the original cytoplasm
