In C. elegans , P granules are described as complexes of RNA and protein that are essential for determining the fate of which specific cell type?

  • A: Muscle cells.
  • B: Epidermal cells.
  • C: Germ cells.
  • D: Neural cells.

Explanation

The text explicitly defines P granules in the context of C. elegans as "specialized cells that give rise to eggs or sperm," which are germ cells. It states, "complexes of RNA and protein direct particular cells to become germ cells. In C. elegans , such complexes, called P granules, can be detected... in cells of the adult gonad that produce sperm or eggs."
