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.
I believe the correct answer is to maintain homeostasis. :)
Answer:
a single genetic disorder that can produce several symptoms ... Marfan syndrome. Genetic heterogeneity is. when the same phenotype may result from the actions of different genes ... An example of a condition that exhibits genetic heterogeneity is ... Polygenic means. the traits are determined by more than one gene.
Explanation:
First person is point of view is this excerpt written. Thus, the correct option is A.

What is the first person point of veiw?</h3>
The people of Oreus received a magnificent reward for putting their trust in Philip's companions and shunning Euphraeus! And the democracy of Eretria deserves a noble reward for driving out your envoys and handing itself up to Cleitarchus!
He granted the Olynthians, who chose Lasthenes to lead the cavalry and exiled Apollonides, a heroic act of mercy. It is foolish and cowardly to hold onto such hopes, to listen to the proponents of the enemy's cause, to refuse to take any action that is necessary, and to think that because you live in such a large city, you will be protected no matter what.
