RNA molecules are very similar to DNA and are attracted to the unzipped DNA. The RNA molecules partner with the single stranded DNA molecules to form a mirror image copy of the DNA. RNA differs slightly from DNA: in place of every molecule of T (thymine) you have a molecule of U (uracil). So, every A in the DNA binds to a U in the newly formed RNA.
