Answer:
DNA Helicase
Explanation:
The process of DNA replication is very complex and requires a variety of proteins in the form of Enzymes.
The DNA replication starts at the site which is about 245 base pairs long and is rich in AT sequences called Origin of replication. The origin of replication recognised by an enzyme called DNA helicase which breaks the hydrogen bonds present between the bases and unwinds the DNA. The RNA primase enzymes then synthesizes an RNA primer which gets attached and to which DNA polymerase binds and add nucleotides.
Thus, the first enzyme that binds to the DNA is DNA helicase.

Explanation:
Protists are very diverse group of organism, it contains all the organisms that does not fits into other kingdom. All of the protists are not heterotrophs some of them are autotrophs. They reproduce sexually but some of them reproduce asexually. Example: amoeba: binary fission. Some of the protists are multicellular. Some of them are unicellular too.
All carbohydrates are made up of carbon, oxygen, and hydrogen.
The chemical formula for Glucose is

.
The chemical formula for Fructose is the same as that of Glucose. The difference between the two is how they are structured.
The chemical formula for Sucrose is

.
As you can see in the chemical formulas of Glucose, Fructose, and Sucrose, they are all made up of the elements carbon, hydrogen, and oxygen.
Explanation:
Monomers are small molecules, mostly organic, that can join with other similar molecules to form very large molecules, or polymers. Polymers are chains with an unspecified number of monomeric units. a polymer. Homopolymers are polymers made by joining together monomers of the same chemical composition or structure.
