D)crossing over
E)evolution

Question

Quizplus · Accepted Answer

The difference in the proteomes of liver cells, mammary cells, and skin cells can be explained by cell differentiation, which involves the activation and inactivation of specific genes to carry out specific functions in a particular cell type, leading to the synthesis of different proteins. Gene splicing and crossing over occur during meiosis and can lead to genetic variations, but they do not explain the difference in proteomes of cells with the same genome. Cell division plays a role in producing more cells, but it does not directly affect the proteome. Evolution is a long-term process that involves changes in the gene pool of a population over time, which is not relevant to the question.
