Label the adjacent sketch of a Lac Operon in a prokaryotic cell with the terms in the chart. Write the function for each.

|Number |Structure |Function |

| |Structural genes | |

| |Operon | |

| |RNA polymerase | |

| |mRNA | |

| |Promoter | |

| |Operator | |

| |Repressor | |

| |Regulatory gene | |

| |Inducer | |

Create Three Venn Diagrams (at least 5 items in each space), comparing the following concepts:

Gene expression/Gene regulation and

Prokaryotic Gene Expression/Eukaryotic Gene Expression and

positive gene controls/negative gene controls OR pre-transcriptional controls/post-transcriptional controls OR pre-translational controls/post-translational controls

In the following diagram of Protein Synthesis, draw, label and explain 6 specific ways that genes can be differentially expressed to result in alternative gene products, different metabolic functions and/or differentiated cells.

[pic]

Distinguish between the terms determination and differentiation with regard to gene expressions. Provide an example and explanation of experimental evidence that supports the claim that different cell types result from differential gene expression in cells with the same DNA.

Distinguish between embryonic versus adult stem cells. Explain (with justification) their arguments for and against stem cell research.
