Diseases From Altered Chromosomes: Cri Du Chat and Chronic Myelogenous Leukemia

The cancerous cells in nearly all CML patients contain an abnormally short chromosome 22, the so-called Philadelphia chromosome, and an abnormally long chromosome 9. These altered chromosomes result from the reciprocal translocation shown here, which presumably occurred in a single white blood cell precursor undergoing mitosis and was then passed along to all descendant cells. … Continue reading Diseases From Altered Chromosomes: Cri Du Chat and Chronic Myelogenous Leukemia

Fetal Testings For Genetic Disorders: Amniocentesis and Chorionic Villus Sampling

Biochemical tests may detect substances associated with particular disorders, and genetic testing can detect many genetic abnormalities. Karyotyping shows whether the chromosomes of the fetus are normal in number and appearance. Source: Urry, Lisa A.. Campbell Biology (p. 289). Pearson Education. Kindle Edition. Fetal Testings For Genetic Disorders: Amniocentesis and Chorionic Villus Sampling (Campbell Biology) … Continue reading Fetal Testings For Genetic Disorders: Amniocentesis and Chorionic Villus Sampling

Evolutionary Implications of Sickle-Cell Disease

Source: Urry, Lisa A.. Campbell Biology (p. 286). Pearson Education. Kindle Edition. Evolutionary Implications of Sickle-Cell Disease (Campbell Biology) The most common inherited disorder among people of African descent is sickle-cell disease, which affects one out of 400 African-Americans. Sickle-cell disease is caused by the substitution of a single amino acid in the hemoglobin protein … Continue reading Evolutionary Implications of Sickle-Cell Disease

News: Scientists Identified Genes Associated With Parkinson’s Disease

Source: Image by Raman Oza from Pixabay By: Ana Pena, Ph.D Researchers have found new gene networks associated with the development of Parkinson’s disease, which may help them understand the underlying mechanisms of this neuro-degenerative disorder and identify potential new therapeutic targets. The study, “The landscape of multiscale transcriptomic networks and key regulators in Parkinson’s disease,” … Continue reading News: Scientists Identified Genes Associated With Parkinson’s Disease

News: E. coli Engineered To Consume Carbon Dioxide

Source: https://www.livescience.com/64436-e-coli.html Authors: Shmuel Gleizer, Roee Ben-Nissan, Yinon M. Bar-On, Melina Shamshoum, Arren Bar-Even, Ron Milo The living world is largely divided into autotrophs that convert CO2 into biomass and heterotrophs that consume organic compounds. In spite of widespread interest in renewable energy storage and more sustainable food production, the engineering of industrially relevant heterotrophic model … Continue reading News: E. coli Engineered To Consume Carbon Dioxide
