Carboxylic Acids. Lipids are a macromolecule we need to survive and many of them happen to contain carboxylic acids. Choose one lipid - could be a particular steroid, fatty acid, or tri-glyceride and discuss its structure and potential reactivity. please cite on source using APA citation format.

Two persons differ in several SNPs (single nucleotide polymorphisms), however, after their proteins are compared, you realize that only some SNPs induce changes in amino acid sequence. What is going on here? How come some SNPs induce amino acid change while others don't? (GENETICS QUESTION)

Does AUG occur only at the start of a protein?  How can a ribosome “know” which AUGs represent start codons? What is the actual link between the amino acid and the mRNA molecule? (IOW=What are the “translating” tools that translate RNA language into amino acid(protein) language?hint#2=there are 64 of them)

The enzyme known as alcohol dehydrogenase is capable of oxidizing ethanol, methanol and other hydroxyl group containing organic compounds into their corresponding aldehydes. Such an enzyme with ___ catalyzes the reaction of structurally related substances. Select one:

a. absolute specificity

b. relative specificity

c. stereospecificity

d. no specificity

suppose you dissolved 2000 U of enzyme in 1 ml of buffer. you take a 20 microlitre of diluted enzyme and add it to 1 ml of substrate solution with a concentration of 0.5mM. how long would it take to covert all of the substrate in the solution? ( assume ideal conditions)

During the mismatch repair of DNA, the repair enzyme

1. will remove several nucleotides on both DNA strands.

2. will remove several nucleotides on one DNA strand.

3. will remove only the mismatched nucleotide.

4. will remove the mismatched nucleotide, and the same enzyme will replace it with the correct nucleotide.

5. is unable to detect mutations.

Financial Accounting:

1- Describe the Double-Declining Balance (DDB) depreciation method. Explain a real life business example of an actual fixed asset being depreciated using the Double-Declining Balance (DDB) depreciation method. (Review pages 454 to 457 & pages 476 to 478)

2- Describe a bond issued at a premium. Explain why an investor would purchase a bond issued at a premium instead of a bond issued at par or a bond issued at a discount. (Review pages 515 to 520)

A 65.0 mL solution of 0.118 M potassium alaninate (H2NC2H5CO2K) is titrated with 0.118 M HCl. The pKa values for the amino acid alanine are 2.344 (pKa1) and 9.868 (pKa2), which correspond to the carboxylic acid and amino groups, respectively.

a) Calculate the pH at the first equivalence point.

b) Calculate the pH at the second equivalence point.

A protein with a wild-type allele (P^wt) and protein with a mutant allele (P^m) are one amino acid in the position 12 of the protein chain. The mutant allele's sequence is 5'CTT whereras the wild-type allele's sequence is 5'CAT.

Using an amino acid chart, find :

P^wt in position #12

P^m in position #12
