Question

11) A scientist found that strain K of the organism Enterobacter aerogenes produces a restriction enzyme. This is the third restriction enzyme to be identified from this organism. What name will this enzyme receive? 12) Restriction enzymes cut DNA and create a) blunt ends b) sticky ends c) one sticky end and one blunt end electrode because 13) When in an electrical field, plasmids will travel toward the a) negative; because the bases have a positive charge. b) negative; the positive charge contributed by the nitrogen containing bases is larger than the negative charge from the sugars and phosphate groups c) positive; the sugar molecules in the backbone have a negative charge. d) positive; the phosphate groups in the backbone have a negative ch

Explanation / Answer

11) The name will be EaeKIII, where Eae represents the mricroorganism, K is the strain and III stands for third

12) Restriction enzymes cut DNA and produce sticky ends.

13) when in an electrical field, plasmids will travel toward the POSITIVE electrode because THE PHOSPHATE GROUPS IN THE BACKBONE HAVE A NEGATIVE CHARGE.
