Place the steps of infection in the correct order

SARS-CoV-2 is brought into the body through the mouth or nose.
The virus uses protein spikes to bind to specific recepters on a human cell.
The RNA from the virus is released into the human cell.
The proteins and RNA use the cell's membrane to form a new virus.
Viruses travel to the surface of the human cell and are released outside the cell.
The human cell's ribosome will translate the viral RNA into proteins including RNA polymerase.

DOK.SCI.1

Watch the second video below, Evolution, which shows how SARS-CoV-2 and other viruses may change over time due to mutations.

Using your knowledge of mutations and the graph from the CDC, how would you classify the Delta variant based on current data:

DOK.SCI.2

HS-LS3-2

Watch the third video below, Detection, which shows several ways to test whether someone has been infected by the SARS-CoV-2 virus.

Watch the fourth and final animation, Vaccination, which shows how different types of vaccinations for SARS-CoV-2 prevent disease.

How do DNA and mRNA vaccines produce spike proteins? Drag each item into the correct category.

Has an artificial membrane to allow it into the human cell
Completes the translation process to create spike proteins that mimic SARS-CoV-2 spike proteins
Is brought into a cell through an inactivated adenovirus
Completes transcription prior to translation

mRNA
DNA

HS-LS3-2

The way that genetic variation appears in a population is through:

1) Through new genetic combinations through meiosis
2) Errors occurring during the replication process
OR
3) Mutations caused by environmental factors.

Make a Claim: Based on what you have watched in the videos, as well as what we have learned in class, which type of mutation do you hypothesize led to the Delta variant of SARS-CoV-2?

DOK.SCI.3

Claim and Evidence:
What would happen to the effectiveness of an original vaccination if a mutation in the virus caused the protein spike to change?
Make a claim that answers the question, then support that claim with evidence. What did you learn about mutations that would support your claim?
