If the ribosomes were damaged and stopped functioning, the cell would likely die because it constantly needs to replenish its proteins including enzymes as well as ribosomal proteins to make more ribosomes!
The two important features that characterize the adaptive immune system are specificity and memory.
The ability of the adaptive immune system to target specific pathogen and generate a tailored immune response against it is termed as specificity.
The ability of the adaptive immune system to remember the first exposure to the pathogen and thus, generate a heightened and more rapid immune response against the same pathogen on subsequent exposure is termed as memory.
