Question

Quizplus · Accepted Answer

Cytoplasmic segregation and induction lead to distinct patterns of gene expression within different cells of an embryo. During early embryonic development, the cytoplasm of the fertilized egg divides into smaller cells, which receive different portions of the cytoplasmic contents. These cytoplasmic contents, such as transcription factors and signaling molecules, can induce different patterns of gene expression in each cell, leading to the differentiation of the cells into various cell types.
