Is Antigenic Shift Alone Likely to Lead to Influenza Pandemics

question 51

Multiple Choice

Is antigenic shift alone likely to lead to influenza pandemics?

• A)Yes-ONLY antigenic shift can lead to the large-scale mixing of gene elements required to produce a pandemic flu strain.
• B)No-ONLY antigenic DRIFT can lead to the large-scale mixing of gene elements required to produce a pandemic flu strain.
• C)Perhaps-but it would most likely be a mixture of antigenic shift AND drift that would result in a pandemic strain.
• D)No-antigenic SHIFT is responsible for changes in the hemagglutinin protein,while antigenic DRIFT is responsible for changes in the neuraminidase protein.You must have changes in both to lead to a pandemic strain.
