In the Sea Urchin, a Massive Diversification of Innate Recognition

question 24

True/False

In the sea urchin, a massive diversification of innate recognition receptors has occurred, resulting in the presence of over 200 TLR genes, over 200 NOD-like receptor genes, and over 200 scavenger receptor genes in the genome of these organisms. These receptors are unlikely to contribute to an enhanced innate immune response in sea urchins, because nearly all of these genes are pseuodgenes.
