    New Insights into Cell Division, DNA Replication and Cellular Respiration

    PRWeb – Tue, Dec 6, 2011

    The BioSciences Magazine EurekaMag.com publishes insights into specific topics in the biological sciences. The latest articles cover Cell Division which is the process by which parent cells divide into daughter cells, DNA Replication as the process of copying DNA during Cell Division, and Cellular Respiration which is a set of metabolic reactions by which cells of living organisms gain energy.

    The BioSciences Magazine EurekaMag.com covers a wide range of topics including biology, agriculture, horticulture, forestry, geography, environment and health. Drawing from this pool of scientific disciplines, it publishes articles, reviews and insights on biological topics including those which have recently become popular. Most of these reviews are included in the Scientific Insights Category of EurekaMag.com.

    The EurekaMag.com insight into Cell Division covers the process of division of parent cells into daughter cells. This insight primarily covers Cell Division in plants and includes one experimental finding that Vicia and soyabean protoplasts obtained from cultured cells regenerated cell walls and underwent sustained cell division after treatment with PEG solution. Increases in cell division, cellularity, and spleen weight coincided with increased production of cellular mediators whereas decreases in cell division, cellularity, and spleen weight were associated with decreased production of cellular mediators. Other studies cover the effects of the "ripening" gas ethylene as well as the growth regulator IAA on cell division in plants. Addition of ethylene inhibited cell division whereas application of IAA was essential for initiation of cell division.

    The EurekaMag.com insight into DNA Replication covers the the basis for biological inheritance which involves copying the DNA of all living organisms. One of the sources of this review cover research results that DNA replication and ultraviolet-induced DNA repair synthesis in permeable human fibroblasts are more sensitive to inhibition by ddTTP than polymerase.alpha and less sensitive than polymerase.beta. It also provides examples of mutations affecting the fidelity of DNA replication in E coli. One example is on how multiple nuclei are formed by DNA replication followed by karyokinesis but subsequent failure of the cells to complete mitosis and divide. The authors conclude that an alternative pathway of DNA replication exists in E coli and that aphidicolin, N-ethyl maleimide and several other compounds inhibit both DNA replication and repair. The same was true for DNA replication in the human epidermis which was strongly inhibited by aphidicolin.

    The insight into Cellular Respiration at EurekaMag.com covers the metabolic reactions in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), to gain energy and release waste products. Cellular Respiration requires sugars and, consequently, increasing the sucrose concentration in the cell medium increases the total level of cellular respiration. That concentration is usually responsible for the rate of cellular respiration which is available for infected cells to regulate its diffusive resistance. For example, poliovirus infections produce a rapid decrease in cellular oxygen consumption and thus affect cellular respiration.

    The Science Magazine EurekaMag.com was launched in November 1998 as the online version of the French science magazine "Eurêka - Le magazine des sciences" published since 1995. During the past decade, it has emerged as a comprehensive aggregator of information on biology, on the applied life sciences agriculture, horticulture and forestry, on the earth sciences, on the environmental sciences, and on the health sciences.

    The Science Magazine has recently been accredited by the Chinese Ministry of Information Industry with the registration number 案ICP备10204677号. The site delivers its content through a number of RSS feeds including a "Most Shared Content" RSS Feed and an @EurekaMag Twitter account. The @EurekaMag Twitter account currently features 44,845 tweets and 798 followers. The site accepts advertisements through the Google AdWords system.
