Question

48 multiple choice 1 point restriction enzymes can generate either blunt ends or sticky ends. sticky ends here mean the ends are double - stranded. the ends contain enzymes to join them together. the ends have bases that are complementary to each other. the ends are non - complementary.

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: Blunt ends are also double - stranded, so this is not a defining feature of sticky ends.
• Option 2: Sticky ends do not contain enzymes for joining; ligase is used for that, so this is incorrect.
• Option 3: Sticky ends are single - stranded overhangs with complementary bases, which allows them to "stick" to complementary ends. This matches the definition of sticky ends.
• Option 4: Sticky ends are complementary, not non - complementary, so this is incorrect.

Answer:

The ends have bases that are complementary to each other. (The option with the radio button selected, which is the third option in the list: "The ends have bases that are complementary to each other.")
