Which of the following succinctly explains differential gene expression? (Use recall strategy.)

• A. Differential gene expression refers to the unequal segregation of ribosomes during cell division, causing daughter cells to synthesize different proteins despite identical genomes.
• B. Different cell types express different subsets of genes from the same genome, producing distinct proteins that determine cell-specific structure and function.
• C. It is a process by which cells permanently destroy half of their chromosomes during development, creating distinct genetic templates for each tissue.
• D. Differential gene expression means each cell type contains different DNA sequences that encode unique proteins unavailable to other cells.

Answer: (B)
