Web1 hour ago · Every cell in our body contains a vibrant population of mitochondria, or, more precisely, of mitochondrial DNA molecules (mtDNAs). Just like members of any population mtDNAs multiply (by replication) and die (i.e., are removed, either by degradation or by distribution into the sister cell in mitosis). An intriguing question is whether all … WebMitosis :: DNA from the Beginning Concept 7 All cells arise from pre-existing cells. When chromosomes were first identified, there was some debate about whether they were artifacts or real cellular components. Some scientists thought that chromosomes might be contaminants or some type of staining imperfections.
