Difference between Euchromatin and Heterochromatin | Chromosomes

Learn about the difference between Euchromatin and Heterochromatin. Difference # Euchromatin: 1. The chromatin fibres in this region are loosely coiled as compared with hetero­ chromatic regions 2. Euchromatin is deeply stained in divisional cycle but less stained in interphase. 3. The region is genetically active and con­tains unique DNA. 4. Euchromatic regions are able to synthesize mRNA in vitro. [...]

Difference between DNA and RNA | Nucleic Acid

Learn about the difference between DNA and RNA. Difference # Deoxyribonucleic Acid (DNA): 1. Except some viruses, RNA is non-genetic material taking part in protein synthesis. 2. RNA is found both in nucleus and cyto­plasm. 3. Usually single-stranded, in some viruses double stranded, e.g., in Reo viruses. 4. Three types - mRNA, rRNA and tRNA. 5. Sugar is present in [...]

Difference between Mitosis and Meiosis | Cell Cycle

Learn about the difference between Mitosis and Meiosis. Difference # Mitosis: 1. The cell divides only once. 2. Mitosis takes place in the somatic cells. 3. Mitosis occurs both in sexually as well as asexually reproducing organisms. 4. The DNA replicates once for one cell division. Prophase: 5. The duration of prophase is shorter. 6. Mitosis is comparatively simple and [...]
