Available in PDF, EPUB and Kindle. Book excerpt: The biological DNA contained in the sperm is formed by the process called gametogenesis. It consists of different phases after which male and female sex cells are formed. The structure of DNA provides a mechanism for inheritance. The conformation adopted by the DNA depends on the level of hydration, the sequence of the DNA, the amount and direction of the super-winding, the chemical modifications of the bases, the type and concentration of metal ions and the presence of polyamines in solution.

Download or read book Heritable Human Genome Editing written by The Royal Society and published by National Academies Press. This book was released on 2021-01-16 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heritable human genome editing - making changes to the genetic material of eggs, sperm, or any cells that lead to their development, including the cells of early embryos, and establishing a pregnancy - raises not only scientific and medical considerations but also a host of ethical, moral, and societal issues. Human embryos whose genomes have been edited should not be used to create a pregnancy until it is established that precise genomic changes can be made reliably and without introducing undesired changes - criteria that have not yet been met, says Heritable Human Genome Editing. From an international commission of the U.S. National Academy of Medicine, U.S. National Academy of Sciences, and the U.K.'s Royal Society, the report considers potential benefits, harms, and uncertainties associated with genome editing technologies and defines a translational pathway from rigorous preclinical research to initial clinical uses, should a country decide to permit such uses. The report specifies stringent preclinical and clinical requirements for establishing safety and efficacy, and for undertaking long-term monitoring of outcomes. Extensive national and international dialogue is needed before any country decides whether to permit clinical use of this technology, according to the report, which identifies essential elements of national and international scientific governance and oversight.
Download or read book Meiosis and Gametogenesis written by and published by Academic Press. This book was released on 1997-11-24 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: In spite of the fact that the process of meiosis is fundamental to inheritance, surprisingly little is understood about how it actually occurs. There has recently been a flurry of research activity in this area and this volume summarizes the advances coming from this work. All authors are recognized and respected research scientists at the forefront of research in meiosis. Of particular interest is the emphasis in this volume on meiosis in the context of gametogenesis in higher eukaryotic organisms, backed up by chapters on meiotic mechanisms in other model organisms. The focus is on modern molecular and cytological techniques and how these have elucidated fundamental mechanisms of meiosis. Authors provide easy access to the literature for those who want to pursue topics in greater depth, but reviews are comprehensive so that this book may become a standard reference. Key Features* Comprehensive reviews that, taken together, provide up-to-date coverage of a rapidly moving field* Features new and unpublished information* Integrates research in diverse organisms to present an overview of common threads in mechanisms of meiosis* Includes thoughtful consideration of areas for future investigation

This book was released on 2012-09-30 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Brief offers a concise, handy overview of the main concepts related to Embryology, revisited through the novel concepts that are applied daily in stem cell research and cell therapy oriented investigations. It is based on three main areas: -The process involved in female gamete differentiation and maturation. The main aspects related to cell biology will be covered and an overview of the epigenetic regulation of gametogenesis will be presented. -Early stages of embryo development with a careful analysis of the regulatory mechanisms driving cleavage, polarization and genome activation. -Stem cell and gametogenesis. The use of the oocyte as a possible source for the derivation of stem cell lines is discussed and depicted as a powerful tool to investigate oocyte potency and asymmetric imprinting. The potential biological implications are evaluated and use of stem cells to derive oocytes is presented.

Download or read book Concepts of Biology written by Samantha Fowler and published by . This book was released on 2018-01-07 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

Download or read book Understanding the Human Genome written by Kristi Lew and published by Enslow Publishing, LLC. This book was released on 2018-07-15 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Completed in April 2003, the Human Genome Project was an international effort to map out and read all the genes that make up Homo sapiens. This book supports the Next Generation Science Standards on heredity and biological evolution by examining the history of genetics and the Human Genome Project, the mechanisms behind heredity, and the types of genetic errors that lead to hereditary diseases. Through simplified explanations of complex scientific concepts, full-color images, and informative sidebars, students will also learn about the ethical issues associated with the program as well how the information gained from the research has given rise to individualized medical tests and treatments.
