A virus is a pathogenic agent, a infections particle, consisting of a core of nucleic acid (DNA or RNA) enclosed in a protein shell. Viruses are, in general, much smaller than bacteria and have a much smaller genome. But their genetic material is of many varieties, unknown in cellular organisms. Some of these are discussed here. Bacteriophage φX174 which attacks [...]
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 [...]
