Select all that apply. correct answer: a single strand the sugar ribose Why is DNA antiparallel? correct answer: Its double strands run in opposite directions. Which of the following base...

primary structure of protein correct answer: linear sequence of amino acids in the polypeptide chain secondary structure of protein correct answer: alpha helix and beta pleated sheet alpha helix correct answer: formed when the carbonyl group of peptide bond forms a hydrogen bond with the amide nitrogen of another peptide 4 aa down the chain; proline is not commonly found among these structures beta sheets correct answer: can be parallel or antiparallel peptide chains forming rows or...

PCB exam 1 questions & answers 2023/2024 Globular proteins fold up into compact, spherical structures that have uneven surfaces. They tend to form multisubunit complexes, which also have a rounded shape. Fibrous proteins, in contrast, span relatively large distances within the cell and in the extracellular space. Which of the proteins below is not classified as a fibrous protein? - ANSWER-Elastase (the ones that are: keratin, collagen, and elastin) Which of the following statements is tr...

WGU Biochemistry Final Review 1. The polymerase chain reaction is a tool used to study protein structure. True False 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 Red Feedback Recall from the section on DNA replication that DNA polymerase needs a primer to begin DNA synthesis. This requirement means the primers will direct the DNA polymerase to only synthesize complementary stran...
