WGU C785 BIOCHEMISTRY FINAL EXAM 2022/2023 REVIEWED (LATEST UPDATE)/GRADED A+ 1. The polymerase chain reaction is a tool used to study protein structure. True False (correct answers)False Feedback PCR is a tool used to amplify a specific segment of DNA. What color is the primer in the following diagram? Red Purple Blue (correct answers)Red Feedback Recall from the section on DNA replication that DNA polymerase needs a primer to begin DNA synthesis. This requirement means the primers...

Assuming 100% reaction efficiency, how many DNA copies are created after the completion of four complete PCR cycles? YOUR ANSWER CORRECT ANSWER 24 16 8 4 5. What is the function of DNA polymerase in the process of PCR? YOUR ANSWER CORRECT ANSWER It separates the two DNA strands so that replication may occur. It recognizes the primers and uses the available dNTPs to replicate the template DNA sequence. It synthesizes primers and uses the available dNTPs to replicate the templat...

WGU C785 Biochemistry Unit Exam Questions Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary Correct Answer: Primary 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. A mutation in the beta-hemoglobin gene, which results in the replacement of the amino acid glutamate in position 6 with the...
