Answer:
DNA
Explanation:
Deoxyribonucleic acid (DNA) is known as the hereditary material of cells. It carries information for coding all type of proteins in the body.
As helicases are proteins, the genetic code from which they are to be made would be present in a specific sequence on part of DNA. This code would be transcribed and mRNA will be formed. After this, the mRNA will be translated and modified into a helicase enzyme.
