Dabei wird zunächst wie gewohnt eine mRNA-Abschrift des Gens angefertigt.
Diese prä-mRNA wird jedoch nicht direkt in ein Protein übersetzt, sondern zunächst zurechtgeschnitten - ein Vorgang, den Genetiker als Spleißen bezeichnen.
www.mpg.deAfter an mRNA copy of the gene has been produced, this pre-mRNA is not directly translated into protein ; instead, one or several pieces are cut out - or spliced out as geneticists put it.
In genes subject to alternative splicing, this can be done in different ways, producing different mature mRNA-molecules and finally various proteins.
