Which protein is responsible for unveiling the dna double helix 2 strands to prepare it for copying

The correct answer is DNA helicase.  

DNA helicases help in the unwinding of DNA. They play an essential function at the time of DNA replication as they distinct the double-stranded DNA into single strands, and permit each strand to undergo copying or duplication.  

It works by melting the hydrogen bonds, which holds the DNA into the double helical composition. The region of the DNA where the DNA helicase has unzipped the DNA is called replication fork.  

the answer is otpion c) understanding

he wants to be heard one more time. he wants to be understood. he needs the truth one more time.

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.
