mouse skin cell. What differences can we expect to see between these two
cells’ nuclear genomes?

more nerve- specific genes.
B) The two cells have almost identical genomes, but the skin cell has more
skin-specific genes.
C) The two cells have different genomes: the nerve cell has nerve-specific
genes but not skin-specific genes, and the skin cell has skin-specific
genes but no nerve-specific genes.
D) The two cells have similar genomes, but the nerve cell has more nerve-
specific genes and the skin cell has more skin-specific genes.
