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.
Sticky ends are overhanging nucleotides that have single-stranded complementary tails.
Restriction endonucleases can cut a DNA sequence to produce two or more shorter sequences with overhanging nucleotides at both ends of the cut DNA strand known as sticky ends or those without overhanging nucleotides known as blunt ends.
The sticky ends are formed from palindromic sequences and can form the complementary base pairs easily.
Therefore, sticky ends are overhanging nucleotides that have single-stranded complementary tails.
