Web4 de jul. de 2024 · Cancer cells often have an abnormal number of chromosomes and the DNA becomes increasingly abnormal as it develops a multitude of mutations. Some of these are driver mutations, meaning they drive the transformation of the cell to be cancerous. WebThe main difference between our genome and bacterial genome is that our DNA molecules are packed into structures we called chromosomes and they are linear, meaning they have a starting point and an end point. Bacteria don't have chromosomes and their DNA is circular. Due to the mechanism of DNA replication, our DNA isn't completely replicated. WebHere are some ways that mitochondrial and chloroplast DNA differ from the DNA found in the nucleus: High copy number.
