How many chromosomes are found in prokaryotes? - one What is another place that can have DNA in prokaryotes? - plasmid Bacteria generally have a? - single large chromosome Super Coiled DNA is - DNA packed and coiled which is held together by proteins. It is not bounded by a membrane. Plasmids - -Extrachromosomal circular DNA -Contain genes which are not necessary for the organism's survival but which may be useful to it (e.g antibiotic resistance genes, genes for enzymes which degr...
