Which statement is most accurate?
A. Hair is different from kidneys because the cells that make up hair and kidneys have different genes.
B. All cells have the same genes, but different genes are active in different cells.
C. As cells and tissues differentiate, they produce new genes.
D. All cells have the same genes, and all of a cell's genes are active at the same time.
Answer (2)
The most accurate statement is B: all cells have the same genes, but different genes are active in different cells, leading to unique cell functions. This highlights the importance of gene expression in cell differentiation. Specialized functions arise because specific genes are turned on or off in various cell types.

The statement that is most accurate is that all cells have the same genes, but different genes are active in different cells, leading to their diverse functions. This principle of gene expression is fundamental to understanding how cells become specialized. Cells like hair and kidney cells express different sets of genes, resulting in their unique characteristics. ;
