If the DNA sequences of a particular gene in a skin cell and a liver cell were compared, there would be
A) a small number of differences.
B) a very large number of differences.
C) so many differences that it would be impossible to identify corresponding genes in skin and liver cells.
D) no differences.

Quizplus · Accepted Answer

The DNA sequence of a particular gene remains constant across different cell types in an individual organism. Skin cells and liver cells have the same DNA sequence for any given gene, reflecting the fundamental principle of genetic continuity in multicellular organisms. Differences in cell function are due to differential gene expression, not differences in the DNA sequence itself.
