Total questions: 20
Worksheet time: 8mins
What are the main components of bacterial cells?
Cell wall, endoplasmic reticulum, lysosomes
Nucleus, mitochondria, chloroplasts
Cell membrane, cytoplasm, ribosomes, DNA, cell wall
Cell membrane, cytoplasm, nucleus, RNA
How do bacteria reproduce?
Bacteria reproduce by binary fission.
Bacteria reproduce by fragmentation.
Bacteria reproduce through sexual reproduction.
Bacteria reproduce by budding.
Describe the lytic and lysogenic cycles of viral replication.
The lytic cycle allows for viral dormancy, while the lysogenic cycle releases new viruses.
The lytic cycle integrates viral DNA into the host genome, while the lysogenic cycle destroys the host cell.
Both cycles result in the immediate destruction of the host cell.
The lytic cycle destroys the host cell to release new viruses, while the lysogenic cycle integrates viral DNA into the host genome, allowing for dormancy.
What is antibiotic resistance and how does it occur in bacteria?
Antibiotic resistance is the ability to withstand the effects of antibiotics, occurring through genetic mutations.
Antibiotic resistance is the process of bacteria becoming more effective at reproducing.
It occurs when antibiotics are used to treat viral infections.
Antibiotic resistance is when bacteria become more sensitive to antibiotics.
What is a difference between bacteria and viruses.
Bacteria can reproduce on their own; viruses need a host cell to replicate.
Viruses have cell membrane and Bacteria don't
Bacteria aren't living and Viruses are.
Bacteria can have double stranded RNA and Viruses can't
What is the function of the Nucleocapsid?
Attaches to host
protects viral genome
Replicates viral genome
No function
What are some common diseases caused by bacteria?
flu
Tuberculosis
HIV/AIDS
Chickenpox
Common cold
Name two diseases caused by viruses.
Tuberculosis
Diabetes
Influenza, HIV
Malaria
The use of microorganisms in medical research and manufacturing is called...
(a)
How do antibiotics differ from antivirals in their function?
Antibiotics target bacteria; antivirals target viruses.
Antibiotics work by boosting the immune system; antivirals work by killing bacteria.
Antibiotics can treat viral infections; antivirals can treat bacterial infections.
Antibiotics are effective against fungi; antivirals are effective against bacteria.
What role do plasmids play in bacterial function?
Plasmids provide bacteria with genetic advantages, such as antibiotic resistance and metabolic capabilities.
Plasmids are responsible for protein synthesis in bacteria.
Plasmids help bacteria in cell division and replication.
Plasmids serve as the main source of energy for bacterial metabolism.
Explain how viruses can mutate and affect their replication.
Viruses cannot replicate if they mutate, leading to their extinction.
Viruses mutate through genetic changes during replication, affecting their ability to infect and replicate.
Mutations in viruses only occur in their protein structure, not in their genetic code.
Viruses replicate without any changes to their genetic material.
What are the symptoms of Latent TB?
Persistent cough
Chest pain
None
Fever
How do vaccines help in the immune response to viruses?
Vaccines cure viruses immediately upon injection.
Vaccines Train the immune system to recognize and fight viruses without causing illness.
Vaccines only work if the person is already infected with a virus.
Vaccines don't help with immune response.
How many Allele do Bacteria have per Gene?
One
Two
Three
Four
Describe the structure of a typical virus.
A typical virus has a core of genetic material (DNA or RNA), a protein coat (capsid), and sometimes an outer lipid envelope.
A typical virus has a rigid cell wall and can reproduce independently.
A virus consists only of a lipid envelope without any genetic material.
Viruses are made up of only proteins and do not contain any genetic material.
Are Bacteriophages a Virus or Bacterium?
Bacteria
Viruses
Neither
The name of the enzyme that makes Bacteria resistant to penicillin is called...
(a)
Can Viruses infect hosts without a protein shell?
Yes
No
Viruses don't have a protein shell
How can understanding bacterial genetics aid in biotechnology?
It allows for the study of human genetics.
It helps in creating vaccines for viral infections.
It improves the taste of food products.
It enables the development of Enzymes
