Worksheets3.2.2 Binary Fission and Viruses
Total questions: 10
Worksheet time: 5mins
What is the process called in which prokaryotic cells divide?
Mitosis
Binary fission
Meiosis
Budding
During binary fission, what happens to the circular DNA in prokaryotic cells?
It is destroyed
It is replicated
It is converted into linear DNA
It remains unchanged
What is the role of plasmids during binary fission in prokaryotic cells?
They are discarded
They are replicated
They are converted into proteins
They are used as energy sources
How many daughter cells are produced from one prokaryotic cell after binary fission?
One
Two
Three
Four
What is the main difference between binary fission and viral replication?
Binary fission involves a host cell
Viral replication involves cell division
Binary fission does not require a host cell
Viral replication does not involve DNA
Why do viruses not undergo cell division?
They lack DNA
They are non-living
They are too small
They have no cytoplasm
What happens to the viral nucleic acid after it is injected into the host cell?
It is destroyed by the host cell
It replicates the virus particles
It becomes part of the host DNA
It remains inactive
In binary fission, what is the variability in the number of plasmid copies in daughter cells?
There is no variability
It is always the same as the parent cell
It can vary between daughter cells
It is always zero
Which of the following is NOT a characteristic of binary fission?
Involves replication of circular DNA
Produces genetically identical cells
Requires a host cell
Involves division of cytoplasm
What is the primary function of the host cell in viral replication?
To destroy the virus
To replicate viral particles
To provide nutrients to the virus
To convert viral RNA to DNA
