IB SL Biology Lab Molecular Biology: Transformation and Electrophoresis Christina Qi 2/16/07 Aim: How can a plasmid be engineered to include a foreign piece of DNA and how does gel electrophoresis separate DNA molecules present in a mixture? Hypothesis: If the pGLO plasmid is inserted into competent Escherichia coli cells‚ then the transformed bacteria will be resistant to ampicillin and will glow green under UV light. If samples of DNA are cut using certain restriction

in modern medicine as they are becoming more and more resistant to antibiotics. Antibiotics were discovered in 1928 by Alexander Fleming (Walsh and McManus‚ 2000). This resulted in a huge movement forward in medical history and even greatened human life expectancy. Since then antibiotics have been widely used and abused‚ people began to treat everything with this ‘miracle’ drug. If antibiotics are continually used as bacteria grows exponentially more resistant to them then eventually society will

Biology- Change in pH Aim: To investigate the affect that change in pH levels has on a particular enzyme‚ in this case amylase. Hypothesis: In this investigation I expect as the pH reaches the optimum level‚ the rate of reaction will be fastest‚ compared to other pH levels. It is also suspected that after the enzyme has reached optimum level the enzyme activity will decrease. Through further study of the optimum level of amylase I found that the enzyme usually has an optima pH of 8. It is known
