In a mutational event
WebWhat makes a frameshift mutational event more serious than a point mutational event? A. Frameshift mutations occur primarily in germline cells, and point mutations occur only in somatic cells. B. Frameshift mutations result in the deletion or addition of whole chromosomes (aneuploidy), and point mutations are undetectable at the chromosome level. WebHere, exploiting the mutational footprint of some chemotherapies, we explore their influence on the evolution of hematopoietic cells. Cells of Acute Myeloid Leukemia (AML) secondary to treatment...
