Explanation: 

Detailed explanation-1: -The spike protein is found on the surface of the virus that causes COVID-19. After the protein piece is made, our cells break down the mRNA and remove it, leaving the body as waste. Next, our cells display the spike protein piece on their surface.

Detailed explanation-2: -The bulbous projections seen on the outside of the coronavirus are spike proteins (red-orange). This fringe of proteins gives the virus its crown-like appearance under the microscope, from which the Latin name corona is derived.

Detailed explanation-3: -The World Health Organization (WHO) has decided to name the disease caused by the novel coronavirus “COVID-19” and refers to the virus that causes it as the “COVID-19 virus.” CO for corona, VI for virus, D for disease, and 19 for the year the outbreak was first recognized, late in 2019.
