Your partly correct only cell devision DNA makes two exact copies that can repear themselves to 100%. When DNA is dammaged by toxic intake true food and environment DNA alters. RNA comes in 3 forms mRNA tRNA and rRNA with each their own fundamental function of the genome translation into practice. However when the genome(DNA) is dammaged the RNA takes over the error and can't fixt it so altered/dammaged proteins get build and altered processes get activated with auto-immuun disease and cancer as a consequence.Genetic mutation is not random it's bonded by toxic environment and ultraviolet light. All chemical elements not from nature in human body (foreign) is toxic and stacksup in organs which leads to disease.

Reply to comment by anon525as in Given that reproduction is difficult or impossible when both animals have different numbers of chromosomes, how did so many species evolve to have so many different numbers of them? by MercurioLeCher
