Titanium metal is obtained from the mineral rutile, TiO2. The process requires multiple steps, as shown in the following reactions:
- (a) Write mole ratios to show the relationship between the reactants and products for each reaction.
- (b) How many moles of TiO2 are needed to form one mole of titanium?
- (c) How many kilograms of rutile are needed to produce 95 kg of Ti?

- Diabetes is a group of metabolic diseases characterized by abnormal regulation of blood glucose levels. If left untreated, diabetes leads to chronic hyperglycemia and numerous pathological complications. Classify each characteristic according to whether it best describes type 1 or type 2 diabetes mellitus.

- Book problem 28-22: Human and horse insulin both have two polypeptide chains, with one chain containing 21 amino acids and the other containing 30 amino acids. They differ in primary structure at two places. At position 9 in one chain, human insulin has Ser and horse insulin has Gly; at position 30 in the other chain, human insulin has Thr and horse insulin has Ala. How must the DNA for the two insulins differ? Book problem 28-24: The codon UAA stops protein synthesis. Why does the sequence UAA in the following stretch of mRNA not cause any problems?

Piefly summarize the process of transcription. Include in your summary a list of at least 2 proteins that are involved in transcription. Your summary should be 2-3 sentences long. B. Pyrrole-imidazole polyamides such as the ones discussed in this paper are designed to bind specific sites on DNA. These types of polyamides can be used to inhibit transcription. a. Explain in 1-2 sentences how a molecule that binds to a specific DNA sequence could inhibit transcription. b. Many types of cancer are caused by problems with transcription. Explain in 1-2 sentences why a molecule like a polyamide would be better for treating a cancer caused by mis-regulations in transcription than a molecule that inhibits the functionality of RNA polymerase II. (Hint, think about side effects). C. A chemist made a similar molecule but rather than using pyrroles and imidazoles, they just used cyclopentane molecules. Would this molecule bind DNA as efficiently as the original polyamide? Explain your answer in…arrow_forward
