Question 1 (1 point)

Which are examples of common viruses our bodies have all likely fought?

Question 1 options:

Chicken Pox

The Flu

Common Cold

All of the above

Question 2 (1 point)
How do viruses replicate in the host?

Question 2 options:

They reproduce through mitosis

They reproduce through meiosis

They hijack the cells factories since they can't replicate on their own

They don't reproduce at all

Question 3 (1 point)
What happens to the cell when a virus reproduces in it?

Question 3 options:

It explodes

It turns into the virus

It shrinks

Nothing happens

Question 4 (1 point)
What happens when the body realizes theirs a virus in it?

Question 4 options:

It can't do anything, because it's too late

Continues to make more viruses

Targets and destroys infected cells

Shuts down vital organs

Question 5 (1 point)
What is responsible for cutting up double stranded RNA?

Question 5 options:

RNA polymerase

DNA Polymerase

Dicer

RNAi

Question 6 (1 point)
Another way the body can fight against viruses is through RNAi. RNAi will take chopped up segments of double stranded RNA and use them against the virus.

What does it prevent the cell from doing?

Question 6 options:

Copying DNA

Making Proteins

Transcription

Making RNA

Question 7 (1 point)
Scientists can use the same basic mechanism of RNA interference to turn off 3 genes at a time to study the effect on the cell and the organism.

Question 7 options:
True
False
Question 8 (1 point)
Human cells naturally fight viruses with RNAi.

Question 8 options:
True
False
Question 9 (1 point)
Understanding how viruses work can be helpful in treating cancer.

Question 9 options:
True
False
Question 10 (1 point)
Saved
What do viruses inject in the cell it binds to?

Question 10 options:

Their genetic code

Their offspring

Other bacteria

Cancer

1 answer

Here are the answers to your questions based on the information provided:

Question 1:
All of the above
Common viruses include Chicken Pox, The Flu, and the Common Cold.

Question 2:
They hijack the cells factories since they can't replicate on their own
Viruses do not have the machinery to replicate themselves, so they infect host cells to utilize the host's machinery for replication.

Question 3:
It explodes
Often, the host cell may lyse (explode) during the release of new viral particles, although it can also go through other processes such as budding.

Question 4:
Targets and destroys infected cells
The immune system recognizes infected cells and works to eliminate them.

Question 5:
Dicer
Dicer is responsible for processing double-stranded RNA into smaller fragments used in RNA interference.

Question 6:
Making Proteins
RNA interference (RNAi) prevents the translation of mRNA into proteins.

Question 7:
True
Scientists can use RNA interference to study the effects of turning off multiple genes at once.

Question 8:
True
Human cells do use RNA interference as a natural mechanism to combat viruses.

Question 9:
True
Understanding viral mechanisms can provide insights into cancer treatments and therapies.

Question 10:
Their genetic code
Viruses inject their genetic material (DNA or RNA) into the host cell to begin the replication process.

These answers should align with your understanding of viruses and their interactions with host cells.
