A researcher is evaluating the role of a growth factor during embryonic development. She notices that this factor functions in both neural development and limb development. How is that possible?
A)The effects of the growth factor may be concentration-dependent.
B)The effects of the growth factor may be dependent on location.
C)The growth factor may result in the transcription of different genes, depending on cell type.
D)The growth factor may be signaling through different transduction pathways.
E)All of these choices are possible explanations for the observations.

Question

Quizplus · Accepted Answer

It is possible that the role of the growth factor is concentration-dependent, dependent on location, resulting in the transcription of different genes depending on the cell type, or signaling through different transduction pathways. All of these explanations are possible reasons why the growth factor functions in both neural and limb development.
