The following points highlight the top three types of non-Genetic ribonucleic acid (RNA). The types are: 1. Messenger RNA (MRNA) 2. Ribosomal RNA (rRNA) 3. Transfer RNA (tRNA). Type # 1. Messenger RNA (MRNA): Monod and Jacob (1961) coined the term 'messenger RNA' to describe the template RNA that carries genetic information for protein synÂthesis from nuclear DNA to ribosomes [...]
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) [...]
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 [...]
