Summary

Automatic Translation

Protokollen beskrevet her er baseret på en genome-wide kvantificering af nyligt syntetiserede mRNA renset fra gærceller mærket med 4-thiouracil. Denne metode gør det muligt for at måle mRNA syntese sammenkædet fra mRNA i tænderne og således giver en nøjagtig måling af RNA polymerase II transskription.
