question 10

Multiple Choice

• B) There are viral proteins that bridge the two sequences.
• C) The two sequences are both on the same side of the helical nucleocapsid.
• D) The polymerase protein is large enough to bind both sequences.
• E) The polymerase does not need to bind to both sequences simultaneously.
