Briefly describe nonrepudiation and its importance for EC and electronic transactions
What will be an ideal response?
Nonrepudiation is assurance that an online customer or trading partner cannot falsely deny their purchase, transaction, etc. For EC and other electronic transactions, including cash machines or ATMs, all parties in a transaction must be confident that the transaction is secure; the parties are who they say they are (authentication), and that the transaction is verified being completed or final. Authentication and nonrepudiation are potential defenses against phishing and identity theft.

You come across an article that discusses a new drug that interferes with hydrogen bonding during protein formation. Based on your understanding of the levels of protein organization, which of the following is a probable consequence following exposure to this new drug?
A. Protein folding will arrest during the formation of tertiary structure. The drug would interfere with the ability of the alpha helix or beta sheet to form the bonds necessary to fold into a globular protein. B. The drug would prevent amino acids from bonding together which would in turn prevent the formation of the primary structure of the protein. C. Protein folding will arrest during the formation of secondary structure. The drug would prevent the polypeptide from forming an alpha helix or a beta sheet. D. The polypeptide would be unable to form a quarternary structure because it would be unable to form the bonds necessary to link up with other protein molecules.
