The “Y” shaped region where new nucleotides are being added during replication is known as a(n):

Organic molecules are composed primarily of carbon atoms bound to other atoms and most inorganic molecules are not.

Explanation:

The organic compounds have as a fundamental element carbon, an element which is tetravalent because it has four covalent bonds. Carbon can form chains of variable length, thanks to that. You can also find hydrogen in those chains that's why we can say that the organic compounds are formed by hydrocarbon chains (carbon and hydrogen). Living things, we do synthesize organic and inorganic molecules and, of course we consumed both.
