UNIQ35c721781d759d23-partinfo-00000001-QINU Results of Beta Gal Tests

ANOVA of BETA GAL Round 1—p=.232 NOT SIGNIFICANT

ANOVA of BETA GAL Round 2—p=.389 NOT SIGNIFICANT

Student t-test Beta Gal round 2

-4 vs -7: t= -1.43 sdev= 6.85 degrees of freedom = 14 The probability of this result, assuming the null hypothesis, is 0.18(Not significant)

-4 vs no iron: t= -1.80 sdev= 9.15 degrees of freedom = 12 The probability of this result, assuming the null hypothesis, is 0.097(Not significant)

-7 vs no iron: t=-0.823 sdev= 9.03 degrees of freedom = 12 The probability of this result, assuming the null hypothesis, is 0.43(Not significant)

Figure #1 (above):Relationship of the Beta-Gal production from the second test. Each category contained n=4 duplicates. Values were averaged and standard deviations were calculated to develop the above graph. Analysis with One-Way ANOVA (p=.389) and Student t-tests between groups showed no statistical significance.

The results from this first round showed a promising difference between the iron concentration of 10^-4 M and no iron, as we expected. This led us to develop a second round of experimentation for look for statistical differences with more samples. Since there was not a significant difference between the groups, we also steered away from looking for a gradient and spent our efforts testing for functionality in the second round of experimentation.

Figure #2 (above):Relationship of the Beta-Gal production from the first round of experimentation. Each category contained n=2 duplicates. Values were averaged and standard deviations were calculated to develop the above graph. Analysis with One-Way ANOVA (p=.232) showed no statistical significance. (NOTE: There were too few duplicates per category to perform Student t-tests between groups.)

Our second round of experimentation did not yield a significant difference between groups, suggesting that our construct is not functional.

Figure #3: (above) The results from Gel electrophoresis demonstrated successful transcription (shown by the bright bands). The results also suggest the presence of our DNA (shown by the lighter bands). Bright bands present at: 8 (RT-PCR) and 9 (PCR, plasmid DNA). Light bands present at: 2 (PCR negative control),6 (RT-PCR), 10 (PCR- same DNA as 3)

Figure #4: (above) Very faint fluorescence shows some potential expression.

Figure #5: (above) Amp plate—plasmid was taken up.

Figure #6: (above) Kan plate—no growth as expected UNIQ35c721781d759d23-partinfo-00000002-QINU
