In this article we will discuss about the organisation of DNA in bacteria. The DNA of bacteria, e.g. E. coli, is a covalently closed circular molecule. It forms the bacterial chromosome, though this chromosome is much simpler in structure and in level of organization than the eukaryotic chromosomes of plants and animals. Also, each bacterial cell normally has a single [...]
The upcoming discussion will update you about the differences between Prokaryotic DNA and Eukaryotic DNA. Difference # Prokaryotic DNA: 1. DNA content is small, less than 0.1 pg. 2. DNA occurs freely inside the cytoplasm. 3. There is nothing like nucleus. 4. Organelle DNA is absent. 5. It consists of a single molecule. 6. It is naked. 7. It is [...]
The upcoming discussion will update you about the differences between Deoxyribonucleic Acid (DNA) and Ribonucleic Acid (RNA). Difference # Deoxyribonucleic Acid (DNA): 1. It usually occurs inside nucleus and some cell organelles. 2. DNA is the genetic material. 3. It is double stranded with the exception of some viruses (e.g., phage f x 174). 4. DNA contains over a million [...]
