Which of the following correctly explains how gene expression can change in a differentiating cell in an animal embryo?A. DNA methylation triggered by apoptosis leads to suppression of some genes and expression of others.B. Presence of germ layers trigger hormonal release from endocrine glands, signaling to certain cells to express genes.C. Cell signals through plasmodesmata allow coordination of cellular activities and cell differentiation.D. Cues from the cytoplasm and from surrounding cells can induce changes in gene expression.

Which of the following best describes the concept of cell differentiation during the development of a multicellular organism? A. During development, all of the genes in the embryo's cells are expressed at first, but fewer and fewer are expressed as time proceeds. B. During development, different sets of genes are deleted from different cell types so that at the end of development, each cell has only the genes it needs. C. During development, different cells become specialized to have different phenotypes even though they all originated from the same cell. ..

In mice, the copy of the Igf2 gene that is inherited from the mother isnever expressed in her offspring. This happens because the Igf2 genefrom the mothera. always undergoes a mutation that inactivates its function.b. is deleted during oogenesis.c. is deleted during embryonic development.d. is not transcribed in the somatic cells of the offspring.
