From Wikipedia, the free encyclopedia
Helicaser er enzymer, der bidrager til DNA-replikation, transskription og andre cellulære processer. Når der skal foregå replikation, dvs. kopiering af DNA-strengen, skal de kodende baser blotlægges, men dette kræver, at DNA-strengens basepar adskilles først. Til denne proces bidrager helicase ved at katalysere opsplitningen af DNA'et i en replikationsgaffel.[1]
