Cells in your hair follicles produce the protein keratin, but cells in your liver do not produce keratin. which statement explains these differences
a). hair follicles contain recombined dna, which create the protein keratin
b). genes are expressed differently in liver cells and hair follicles
c). hair follicle cells contain different genes from liver cells
d). hair follicle cells do not produce dna, but liver cells do

B). Genes are expressed differently in liver cells and hair follicles

Explanation:

In given organisms all the cells of the body have the same number of genes, however, their activity varies due to differential expression of genes.

The differential expression of genes is regulated by several factors, such as histone modifications, DNA, etc. which may silence or activate the genes differentially in different cells.

Since the hair cells and liver cells of the organisms will have the same genes, they only vary due to the differential expression fo the genes.

B) Genes are expressed differently in liver cells and hair follicles

Explanation:

Cell differentiation helps produce different cells with different functions that express different genes in the genome.

Liver cells and hair follicles are an example of cell differentiation creating different functions in multi-celled organisms.

is this a question? wassup
