Verified step by step guidance1
Understand that all cells in an organism contain the same DNA, but not all genes are expressed in every cell.
Recognize that gene expression is regulated and varies between different cell types, allowing cells to perform specialized functions.
Learn that during development and in response to environmental signals, cells activate specific sets of genes while repressing others.
Consider examples such as muscle cells expressing genes for muscle proteins, while nerve cells express genes for neurotransmitters.
Conclude that different cells express different genes based on their function, not randomly or uniformly across all cells.
