Document Summary
1st mid-term: covers first 4 lectures, june 5, 5-7pm. 2nd mid-term: cover first 8 lectures, july 12, 7-9pm, sy110. Chemical reactions that usually take many years to complete can be completed shortly with the help of enzymes. Role enzymes & proteins allow the cells to carry the chemical process. Multiple disciplines, including biology, chemistry, cell & molecular, thermodynamic, organic chemistry, genetics. Chemistry of life: four key concepts (slide 8) Biological chemical reactions are reversible using another enzyme to carry out the opposite reactions. Tata box binding probes in 3 different organisms, including 1) sulfolobus acidicaldarius: arabidopsis thaliana, 3) homo sapiens. Function of the tata box: drive the transcription of rna polymerase. At the amino acid level, the 3 proteins from the diagram look similar in terms of conformation. Despite the differences in the amino acid sequence in the 3 organisms, folding of the protein plays an important (larger) role in determining the function of the protein.
