Question
Do all cells of the body express the same genes?No, since they don't contain the same DNANo, since they don't all need to make the same proteinsYes, since they all make the same proteinsYes, since they all contain the same DNA
Solution
No, not all cells of the body express the same genes. While it is true that all cells in an organism contain the same DNA, not all genes are expressed in every cell. This is because different cells have different roles and therefore need to produce different proteins. For example, a liver cell does not need to produce the same proteins as a brain cell. Therefore, even though all cells contain the same DNA, they do not all express the same genes.

Can one gene make different proteins?Group of answer choicesNo, because one gene can code for only a single proteinYes, by modifying the original DNAYes, by splicing the resulting mRNA differently (i.e., removing different exons)No, because genes do not make proteins
