New Reviews on AdN, Incomplete Dominance and Molasse Published at EurekaMag.com
The BioMedical Magazine EurekaMag.com publishes articles on specific topics in the biological and medical sciences. The latest inclusions cover AdN which is an abbreviation for Adenine nucleotides, Incomplete Dominance which is is a form of intermediate inheritance, and Molasse which are sandstones, shales and conglomerates formed as terrestrial or shallow marine deposits in front of rising mountain chains.

The BioMedical 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 on biological and medical topics including those which have recently become popular. Most of these reviews are included in the Scientific Keywords Category and in the Science Reviews Category of EurekaMag.com.
The EurekaMag.com article on AdN covers Adenine nucleotides which play important roles in biochemistry including cellular respiration and protein synthesis. They are also chemical components of the energy-rich adenosine triphosphate (ATP), the cofactors nicotinamide adenine dinucleotide (NAD) and flavin adenine dinucleotide (FAD), and deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The EurekaMag review on AdN covers a study of AdN concentration during different growth phases of the fungus Candida albicans. It also shows that the content of adenine nucleotides in closed buds of Quercus robur increased temporarily between mid-Feb and mid-March and that the main increase in AdN concentration appeared when buds became swollen or at bud break. The article also covers AdN-gene expression in human tissues. Unlike AdN, its receptors are expressed in many human tissues. Human R2 expression is not highest in the liver but in AT where it is associated with MMIF expression.
The EurekaMag.com review on Incomplete Dominance covers this form of intermediate inheritance in which one allele for a specific trait is not completely dominant over the other allele. A very well known example is that of snapdragon plants. When red and white snapdragons are crossed, the dominant allele that produces the red color is not completely dominant over the recessive allele that produces the white color and the resulting offspring are pink. The article provides other examples including one on the plant pathogen Erysiphe graminis f. sp. avenae. Two genes showed complete dominance of resistance to eight races and incomplete dominance towards two. It also presents incomplete dominance in Morning Glory in which the mutable a allele exhibits incomplete dominance. In this flowering plant not only intensely colored flakes but also white spots and sectors are often observed in lightly colored flowers.
The article on Molasse at EurekaMag.com covers the sandstones, shales and conglomerates formed as terrestrial or shallow marine deposits in front of rising mountain chains. It presents the influence of the Alpine upliftment and associated geographic changes on the regional climate between the Bavarian Molasse to the Vienna basin by investigating the faunal assemblages and geochemistry of Miocene marine and brackish ostracods of their Molasse sediments. The 18O values for marine fossils of the Molasse between 20 and 13 Ma reflect global changes in climate when comparing them with records of climatic change from the global oceans. This is also true for the increasingly brackish conditions up to 11 Ma, where combined geochemical records are still compatible with the global changes in temperatures. Near Lausanne, remains of large mammals have been recovered from de “Molasse grise de Lausanne” over a long period of time. Among the spectacular fossils are jaws and isolated teeth of rhinoceroses, pigs and ruminants.
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.
