Exit Ticket: Problem 6 Molecular Biology Workflow (Initial check)

A quick check on today's hinge idea. Enter your Student ID, answer each item, and submit. You will see your result right away. This is practice, not a grade.

1. 1. A restriction enzyme is used in cloning to:

   ACut DNA at a specific sequenceBMake many copies of a DNA regionCJoin two DNA fragments togetherDRead the order of the DNA bases

2. 2. A plasmid and an insert are both cut with EcoRI. Cutting both with the same enzyme gives:

   ATwo pieces of exactly the same lengthBA plasmid that needs no ligaseCSticky ends that match and pair upDEnds that must be filled in first

3. 3. A cut plasmid is mixed with ligase, but no insert is added. What happens to most of the plasmid?

   AIt is cut into smaller piecesBIt closes back on itselfCIt is copied many timesDIt stays a straight line
