Explanation:

• DNA Helicase: Its function is to unwind or 'unzip' the double - stranded DNA molecule. This separation of the DNA strands is essential for processes like replication and transcription as it provides the single - stranded templates required.
• DNA Polymerase: In DNA replication, it synthesizes a new complementary DNA strand. It reads the existing DNA strand (template) and adds nucleotides according to the base - pairing rules (A - T, C - G).
• RNA Polymerase: During transcription, it reads the DNA template strand and builds an mRNA (messenger RNA) strand. It follows the base - pairing rules (with Uracil (U) in RNA instead of Thymine (T) in DNA when pairing with Adenine (A)).

Answer:

• DNA Helicase: 'unzips' DNA for replication
• DNA Polymerase: builds a complimentary DNA strand during replication
• RNA Polymerase: reads DNA and builds an mRNA strand during transcription
