All cells in a multicellular organism share the same genome. Cells differ in function because of
- A
Different chromosome numbers maintained in each specialized cell type
- B
Different genomes inherited by each tissue type during development
- Ccheck_circle
Differential gene expression — different sets of genes are turned on/off
- D
Different DNA sequences arising in each tissue through somatic mutation
Explanation
Tissue identity is determined by which genes are expressed, not by genome differences.
