>what is a helicase? you mean helix?

DNA helicases are a class of proteins which are involved in the unwinding
of DNA, I believe. A diagram depicting a helicase is found at:

In the previous post I should have strictly said: The Werner's syndrome
gene (WRN) has been identified and the protein it codes for is similar to
a DNA helicase. The previous post does state: Helicases are involved in
DNA replication, recombination, chromosome segregation, DNA repair,
transcription or any function that requires unwinding of the DNA.
