Help yourself to a piece of 11 by 17 paper. Put your name on it.
ONE SIDE OF PAGE:
Answer the following questions using illustration and using the vocabulary words:
Lac Operon
structural gene
operator gene
regulator gene
cAmp
glucose
lactose
Cap
Promoter, Operator
Lac z, Lac y, Lac A
1. What is the purpose of the Lac Operon?
2. Draw the Lac Operon, and label the regulator gene, he cap, promoter, operator, lac z, lac y, lac A and the RNA polymerase creating the mRNA. Draw, label and identify the three proteins encoded by lac z, y and a
3. label the purpose of the three proteins encoded by lac z, y and a
4. Explain in an illustration how the lac repressor works
a. to inhibit mRNA synthesis in the absence of lactose
b. to cause mRNA synthesis to happen in the presence of lactose
c. Include the role of cAMP in your illustration
OTHER SIDE OF PAGE:
Draw mitosis and meiosis, side by side. Assume 2n=4 and n=2
label and colour code the chromatin/chromosomes/chromatids. Explain what happens in each step. Include the following words: diploid, haploid, homologous pairs, centrioles, spindlefibres, interphase, prophase, metaphase, anaphase telophase
