Question 12

A skin cell and a muscle cell are taken from the same person. Which statements about these two cells are true? Select all that apply.

  1. They contain the same genesBonne réponse
  2. The skin cell contains only skin genes
  3. Different genes are switched on in each of themBonne réponse
  4. The muscle cell has thrown away the genes it does not use

Explication

Every body cell of one individual grew from the same fertilised egg and keeps the full set of genes, so what separates a skin cell from a muscle cell is which of those genes are active. If cells kept only the genes they use they would have to discard genetic material, and ordinary growth does no such editing.
