The SARS-CoV-2 non-structural protein 1 (Nsp1), also referred to as the host shutoff factor, suppresses host innate immune functions. By combining cryo-electron microscopy and biochemistry, we show that SARS-CoV-2 Nsp1 binds to the human 40S subunit in ribosomal complexes, including the 43S pre-initiation complex and the non-translating 80S ribosome. The protein inserts its C-terminal domain into the mRNA channel, where it interferes with mRNA binding. We observe translation inhibition in the presence of Nsp1 in an in vitro translation system and in human cells.
Explanation:
Plant) Banana
Trait: Smaller seeds, larger fruit, thinner skin
People breed plants to gain desired produce with more yield. After years of genetic nurturing, the perfect bananas were created with smaller seeds, larger sizes, and an offspring with greater abundance for maximum profit.
Animal) Chihuahua
Trait: Smaller size
Chihuahuas are a great example of artificial selection in a domesticated animal because over time people successfully breaded different dogs to acquire the size of the chihuahua.
Answer:
C. Viruses require cells to survive and reproduce
Explanation:
Viruses are considered <u>non-living organisms because they are not able to survive and reproduce on their own</u>. Instead, they select a cell, also known as a <em>host</em> cell, where it can reproduce. Once the virus finds this host, it injects it genetic material and takes over its functions.
Therefore, <u>they highly depend on another cell to survive and reproduce</u>. This could lead scientists to think that viruses evolved after cells, as they wouldn't be able to survive without them.
