Some students are critiquing explanations of the role of dna in cell differentiation. which statement should they select as the most accurate scientific explanation?
a.
although the cells within an organism contain the same dna, cellular rna has a more important role than dna in cell differentiation.
b.
because the dna within each of an organism’s cells varies, dna variation results in cell differentiation.
c.
although all of the cells within an organism contain the same dna, different parts of the dna are active in different cells, resulting in differentiation.
d.
because environmental factors are the primary cause of cell differentiation, it is possible for cells to differentiate into other kinds of cells, regardless of their dna content.
