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 [...]
The following points highlight the four major phases of the cell cycle. The phases are: 1. G1 (gap1) phase 2. S (synthesis) phase 3. G2 (gap 2) phase 4. M (mitosis) phase. Cell Cycle: Phase # 1. G1 Phase: The G1 phase is set in immediately after the cell division. It is characterised by a change in the chromosome from [...]
