Question

28. Below are two models of cells processes.Which model best explains how each type of cell results in a different structure with a specialized function from the same original cell?Model 1 because nerve cells and bone cells receive the same DNA; however, only specific parts of the DNA are activated in each cell.Model 2 because nerve cells and bone cells begin with the same structure; however, bone cells harden over time.Model 2 because nerve cells and bone cells receive the same DNA; however, bone cells receive more to make the protective outer covering.Model 1 because nerve cells and bone cells receive different DNA that determines the structure and function that each will perform.

Answer 1

Step-by-step explanation:

Remember both intracellular transcription factors and extracellular signaling pathways participate in cell differentiation. Intracellular transcription factors cause certain parts of DNA to be expressed in cells and have specific functions. In fact, in every cell, there is selective genetic or epigenetic regulation of gene transcription.

Thus, we can conclude that the correct answer is:

Answer:

Model 1 because nerve cells and bone cells receive the same DNA; however, only specific parts of the DNA are activated in each cell.
