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 [...]
The below mentioned article provides an overview on Ribonucleic Acid (RNA). In broad features, the chemistry of RNA is comparable to the chemistry of DNA. The chemical analysis shows the following two main differences in the polynucleotide chains of DNA and RNA: (i) The sugar in RNA is ribose whereas it is deoxyribose in DNA. (ii) While in DNA, the [...]
The following points highlight the five main classes of chemical compounds in chromatin. The classes are: 1. Nucleic acids 2. Basic proteins or histones (protamines in sperm nuclei of some fishes and birds) 3. Acidic proteins (Non-Histones) 4. Lipoproteins 5. Associated inorganic molecules. Chemical Compounds in Chromatin: Class # 1. Nucleic Acids: The nucleic acids are of two types: (i) [...]
