Summary Introduction
To tell:
Why HIV replicates only in certain human cells and how scientists are able to culture HIV nowadays.
Introduction:
Without any involvement of the living organism, the cell is grown and cultivated and is termed as cell culture. In the cell culture technique, different methods are followed to provide the same environment that is present inside living organisms. The techniques involved are to provide nutrients to a stable condition for them to grow and make passages of it. The cell culture is to help the in-vivo tests.

Why is a webbed plate capable of producing a higher lysate titer (pfu/mL) than a cleared plate?
a.) A webbed plate has plaques that have gone through more rounds of replication because the number of host cells did not limit phage replication, creating exponentially more phage particles
b.) A webbed plate has no more host available for replication, meaning the plate is full of exponentially higher amounts of phage
c.) A cleared plate has less bacteria than a webbed plate, so there are more plaques present
d.) A cleared plate contains more phage than a webbed plate because it started with a more concentrated phage sample
Which of the statements is TRUE about conjugation?
a)
Plasmid DNA is transferred from a donor (F+) cell
b)
It may only be performed by competent cells
c)
DNA is always integrated into recipient chromosome
d)
It may be specialized or generalized
In the mid-1990s, researchers discovered an enzyme in HIV called protease. Once
the enzyme's structure was known, researchers began developing drugs that fit into
the active site and blocked it. This strategy for stopping HIV infections is an example
of what phenomenon?
OA) feedback regulation
OB) competitive inhibition
OC) immunization
OD) allosteric regulation

- You are designing a phage therapy for a cystic fibrosis patient with an multi-antibiotic resistant Mycobacterium infection. The Mycobacterium infection is preventing the patient from taking immunosuppressant drugs that are needed for a successful lung transplant. The idea is that introducing the right phage to the patient will kill the Mycobacterium cells and allow the patient to go on immunosuppressant drugs that will ensure the new lung is not rejected by the body. You finally find a phage that you think will work because it attaches to and injects its genome into the patient's Mycobacterium isolate. Next, you need to be sure of what characteristics of the phage infection cycle? Pick all that are true A. That the phage delivers new antibiotic resistance genes to Mycobacterium via transduction B. That the correct proteins are expressed during the phages metabolism C. That the infection is lytic D.That lysogeny is the primary infection pathwayarrow_forwardDespite our advancement in Science and Technology, thanks to the invention of the early scientists Robert Hooke and Antonie Philips van Leeuwenhoek that paved the way to the discovery of cells and the cure of many diseases, why is it that there are still many who are hesitant to have themselves immunized by COVID-19 vaccines?

- (there are multiple right answers to this homework question but I can't tell which one is right) You are designing a phage therapy for a cystic fibrosis patient with an multi-antibiotic resistant Mycobacterium infection. The Mycobacterium infection is preventing the patient from taking immunosuppressant drugs that are needed for a successful lung transplant. The idea is that introducing the right phage to the patient will kill the Mycobacterium cells and allow the patient to go on immunosuppressant drugs that will ensure the new lung is not rejected by the body. In the first step of your phage therapy design process, you isolate the exact Mycobacterium strain from the patient. What is the most important thing must you establish next about this bacterial isolate? That the isolate is genomically stable so you can study it That the isolate is similar to Mycobacterium in other patients That the isolate rapidly evolves due to horizontal gene transfer That the Mycobacterium is…arrow_forwardA new virus has been determined to triple its population size every 5 hours.
