Does a eukaryotic cell have plasmids
WebBacterial DNA – a circular chromosome plus plasmids. The DNA of most bacteria is contained in a single circular molecule, called the bacterial chromosome.The chromosome, along with several proteins and RNA molecules, forms an irregularly shaped structure called the nucleoid. This sits in the cytoplasm of the bacterial cell.. In addition to the … WebNo, humans do not make plasmid DNA. All human DNA is found within our linear chromosomes. ... Plasmids are naturally occurring in Bacteria and rarely in Eukaryotic cells. For Bacteria, which have nucleoid, the plasmid is pretty useful carrying additional genes such as antibiotic resistance or lethal mutation. It also helps horizontal gene transfer.
