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.
Answer:
The glucose making part of photosynthesis takes place in the stroma
explanation:
Stroma is the colorless liquid that surrounds the grana in the chloroplast inside plant cells. The stroma contains grana, and stacks of thylakoids in which photosynthesis is started before the chemical changes are completed in the stroma itself. The stroma functions by synthesizing organic molecules from water and carbon dioxide. In the stroma, an enzyme removes the carbon from carbon dioxide, and then combines it with hydrogen and oxygen and to form a simple carbohydrate molecule (glucose).
Answer:
Plasma
Explanation:
Plasma carries water, salts, and enzymes. The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma. The plasma then helps remove this waste from the body.
