Nearly all human cells do not multiply continuously but are slow-replicating and devote a big part of their energy to transcription, state the authors. DNA harm can miscode at the broken site and create mutant transcripts. This technique is usually transcriptional mutagenesis and may lead to the production of mutant proteins and could therefore be important in tumor development.
