Answer: A chemical reaction is the change of a substance into a new one that has a different chemical identity. In summary, a chemical reaction is a process that converts one or more substances to another substance. Chemical reactions start with reactants and convert them into products. Most chemical reactions inside living things are regulated by enzymes, which speed up chemical reactions.A chemical reaction is a process that changes or transforms one type of chemical into another. ... Life is the result of countless reactions happening all at the same time, most often between carbon, hydrogen, nitrogen, and oxygen atoms. Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. ... A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

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.
