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.
Scientists
can also glimpse the awful effects of Alzheimer's disease when they look at
brain tissue beneath the microscope:
Alzheimer's tissue has numerous fewer nerve
cells and synapses than a well brain.
<span>
<span>Plaques, unusual
clusters of protein particle, which are construct up between nerve cells.</span>
</span>
<span>
<span><span>Dead and dying nerve cells contain tangles,</span> which
are produce of twisted strands of a further protein.</span>
</span>
<span>Scientists
are not absolutely sure what causes cell death and tissue deficiency in the
Alzheimer's brain, but plaques and tangles are key suspects.</span>
