In this article we will discuss about the subject-matter and structure of Ribosomes present in the cells of plant and animals. Subject-Matter of Ribosomes: In the cytoplasm of the cell there are found particles composed of RNA (ribonucleic acid) and proteins. These are called ribosomes. These particles occur in all the cells that synthesize proteins and they are involved in [...]
Learn about the Comparison between Meiosis and Mitosis. Comparison # Meiosis: 1. In mitosis, chromosome doubling is followed by separation of daughter chromosomes, i.e., there is division of centromere in mitosis. 2. Mitosis occurs in all the cells of the body. 3. It completes in one sequence of stages, i.e., there is only series of divisional stages. Prophase: 4. Prophase [...]
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 [...]
