In Protein Synthesis...
DNA first gets uncoiled( opens helix) then unzips(break H-bond between N bases). Which particular enzymes does it?

Helicase or RNA Polymerase?

Proteins are made when mRNA is translated in the cytoplasm by the ribosomes.
mRNA is made from DNA. Since mRNA is an RNA, RNA polymerase.

Both Unzip and Uncoil are done by RNA Polymerase? Then what does Helicase do?

No. A helicase 'unwinds' the DNA in terms of breaking the H bonds between bases, allowing for DNA replication or transcription. I think you're using 'unzip' and 'uncoil' as synonyms here.

RNA Polymerases work in conjunction with helicase during transcription. But the helicase is still needed to 'unzip' the DNA to allow access for the RNA Pol

Nope, my 'uncoil' I meant opening the coiled helix structure of DNA, and by 'unzip' I meant breaking H-Bond.
