Restriction endonucleases are especially useful if they generate sticky ends. What makes an end sticky?
Mazyrski [523]

The question is incomplete as it does not have the options which are:

A) single-stranded complementary tails

B) blunt ends

C) poly-A sequences

D) 5' cap

E) interference

Answer:

A) single stranded complementary tails

Explanation:

Restriction endonuclease is the enzyme which cuts the DNA sequence in the internal sequence.

The endonuclease enzyme can cut the DNA sequence in a way that it can form the cuts with the single-stranded overhangs called sticky ends and without overhangs called blunt ends.

The sticky ends are produced when the enzyme makes cut at the single strand and then makes the cut at between the same base at the nitrogenous base. This type of asymmetrical cut forms the single-stranded overhangs which can form the complementary base pairs easily.

Thus, Option-A is correct.

The complete question is as follows:

The picture shows an organ system in the human body.

Brain, Nerve, and spinal cord.

What do these organs do in the human body?

  • They filter pathogens and dead cells out of lymph before it returns to the blood.
  • They monitor and react to changes in the body and its environment.
  • They release hormones that control the activities of cells and organs.
  • They identify and destroy things that are foreign or harmful to the body.

Therefore, the correct option for this question is B, i.e. They monitor and react to changes in the body and its environment.
