UNIT 4 TEST Question 1 Which of the following could be a potential ramification of a defective nucleotide excision repair (NER) pathway? Thymine dimers would accumulate and increase the probability of developing skin cancer. =>. A defective nucleotide excision repair pathway would not be able to repair thymine dimers. The accumulation of thymine dimers would increase the probability of developing skin cancer. The correct answer is “Thymine dimers would accumulate and increase the p...

Unit 2 Quiz 1. Which level of protein structure is disrupted through the hydrolysis of peptide bonds? a. Primary b. Tertiary c. Secondary d. Quaternary Answer: A. The primary structure of a protein is the sequence of amino acids held together by peptide bonds. Peptide bonds are formed by dehydration reactions and disrupted by hydrolysis. 2. A mutation in the beta-hemoglobin gene, which results in the replacement of the amino acid glutamate in position 6 with the amino acid valine, leads...

WGU C785 Final Exam What is the basic structure of an amino acid? What do they look like? (ANS- amino group (NH2 or NH3), carboxyl group (COO or COOH), alpha carbon (C), and variable group How do you identify the 3 different types of side chains: non-polar/hydrophobic, polar, and charged? (ANS- Non-polar/hydrophobic - end with CH or "can't have" water. Polar - end with OH, SH, or NH. Charged - end with a charge what kinds of bonds do each of the 3 different types of side chains make? ...
