Answer:
Angiotensin II atrial natriuretic peptide(ANP) lowers blood pressure.
Explanation:
Increase in plasma volume leads to increase in blood pressure and a decrease in plasma level also leads to a decrease in the blood pressure. ANP is an enzyme which stimulates the decrease in blood levels through certain factors thereby causing a decrease in the blood pressure.
Meanwhile ADH stimulates increase in blood plasma levels thereby increasing the blood pressure.
Firstly, the enzyme, DNA Helicase breaks the Hydrogen bonds between a specific region of the DNA molecule and unwinds the duplex DNA molecule at the targeted gene sequence site.
Then, RNA Polymerase binds at the 3` site of the gene sequence of the sense/coding strand(only one strand) that acts as the template for mRNA synthesis. RNA Polymerase then matches free nucleotides by complementary base-pairing(A-U & C=G), working in the 5`to3` direction. Hydrogen bonds then form between the complementary bases, holding the nucleotides in place. Each free adjacent nucleotide is joined at 3` ends by Condensation reactions with the other to form Phosphodiester bonds.
Once the mRNA molecule is formed, it is separated from the synthesis complex and leaves the nucleus through pores in the nuclear envelope to moves towards ribosomes for Translation.
Lastly, the DNA double helix rewinds by forming Hydrogen Bonds.
Because the cell membrane controls what enters and leaves the cell. It also gives the cell support and protection and helps maintain homeostasis. Hope it helps you
