Biology 93
Gene Regulation and Development
Embryo development of most organisms→ single celled zygote produce cells of
different types, each has different structure and function
Cell types organized into tissues→ organs→ organ systems→ whole organism
Transformation from zygote → adult are from cell division, cell differentiation,
morphogenesis
Cell differentiation- cells specialize in structure and function
Morphogenesis- physical process that gives organisms its shape

Different gene expression is a result of genes being regulated differently in cell
types
Materials in egg set up gene regulation, which is carried out as cells divide
Zygote divides by mitosis, different cytoplasmic determinants lead to different
gene expression
