BioChem C785 - WGU - Module 1 - all questions and answers DNA replication is semiconservative, which allows each of the 2 strands to serve as a template for the new strands - CORRECT ANSWER true Recall that the DNA polymerase must bind a double-stranded polymer before it can start making its own DNA polymer. What helps the DNA polymerase to overcome this problem in DNA replication? - CORRECT ANSWER RNA primers Several components of cigarette smoke, including benzopyrene, insert themselves...

WGU C785 - Biochem- Module 2 with complete solutions Deedra's dad has Alzheimer's Disease (AD) which is caused by a change in protein structure - True Alzheimer's disease is caused by aggregation of the Amyloid beta peptide and tangle formation by the tau protein. What kinds of amino acids are likely to drive the formation of these protein aggregates? - hydrophobic After learning about Alzheimer's disease and one of the drugs used in its treatment, what other drug design strategies...

BioChem C785 module 2 quiz, Answered Fully Which image below shows the carboxyl group of an amino acid circled? - An amino acid consists of an amino group, carboxyl group, a hydrogen and a variable side chain arranged around a central alpha carbon atom. The backbone of an amino acid is the entire amino acid molecule minus the variable side chain. The carboxyl group of an amino acid is shown as COO_ or COOH attached to a central alpha carbon atom of the amino acid. Which of the following s...
