A circular chromosome is a chromosome in bacteria, archaea, mitochondria, and chloroplasts, in the form of a molecule of circular DNA, unlike the linear chromosome of most eukaryotes. Most prokaryote chromosomes contain a circular DNA molecule – there are no free ends to the DNA. Free ends would otherwise create significant challenge… WebDNA and bacteria are not comparable as they are completely different. DNA or deoxyribonucleic acid is the genetic material of organisms-- bacteria as well as …

WebCircular DNA also circumvents the Hayflick limit (thus allowing it to be "immortal"), which is the number of times a cell population can divide before it stops, presumably due to the shortening of telomeres, the sequences at the end of the chromosomes. Since circular DNA lacks telomeres, it does not get shorter with each replication cycle. Weba. Most bacteria and archaea have circular DNA in the cytoplasm, while most eukaryotes have linear DNA in the nucleus. b. Archaea and eukaryotes have histone proteins associated with their DNA, while bacteria do not have histones. c. All of the DNA in eukaryotic cells is contained within a nucleus. d.

They are most commonly found as small circular, double … WebCircular DNA molecules that are of great significance in nature as well as in numerous biotechnology applications are plasmids, which are widespread among bacteria. …

WebAfter the circular DNA is inserted in the bacteria: DNA polymerase in bacteria copies the plasmid. The bacteria then divide by binary fission so that each daughter cell has several copies of the plasmid. The bacteria transcribe the new gene and may be translated to give the required gene product.
