Issues surrounding newborn and infant nursing are global. In efforts to acknowledge the international community, each Newborn and Infant Nursing Review NAINR issue will feature a column that highlights care-related issues from a featured country or region of the world.
This article focuses on Kenya. Newborn and infant health issues are global ones. To review issues occurring in different areas of the world, a different area of the globe will be featured that addresses NAINR's theme-oriented topic. This month, Kenya will be featured. This month's article focuses on genetics. The molecular material, which is the material that changes most rapidly in genetics, is current and presented at a suitable level for students.
Enhanced for this edition is the coverage of genomics, the analysis of the information contained within complete genomes of organisms. Experimental Approach. Research is the foundation of our present knowledge of genetics. The presentation of experiments throughout iGenetics allows students to learn about the formulation and study of scientific questions in a way that will be of value in their study of genetics and, more generally, in all areas of science.
The amount of information that students must learn is constantly growing, making it crucial that students not simply memorize facts, but rather learn how to learn. In my classroom and in this text I emphasize basic principles, but I place them in the meaningful context of classic and modern experiments.
Thus, in observing the process of science, students learn for themselves the type of critical thinking that leads to the formulation of hypotheses and experimental questions and, thence, to the generation of new knowledge.
Classic Principles. Our present understanding of genes is built on the foundation of classic experiments, a number of which have led to discoveries recognized by the Nobel Prize. These classic experiments are described so that students can appreciate how ideas about genetic processes have developed to our present-day understanding. CRISPR, a genome-editing tool, is a straightforward technique that allows specific, highly accurate modification of DNA sequences within genes and is thus a powerful tool in the world of genetic research and gene therapy.
In addition to this chapter, we call your attention to the introduction to Chapter 1 for an introduction to CRISPR and to also note that we have chosen this gene-editing system as the subject matter illustrated on the cover.
Special Topics Chapter 6 illustrates the many of advances that have been made in the study of human neurogenetics. Huntington disease, a monogenic human disorder, has been subjected to analysis for over 40 years using every major approach and technique developed to study molecular genetics, and as such, exemplifies the growing body of information that has accrued regarding its causes, symptoms, and future treatment.
Additional new chapters arise from a major reorganization and expansion of our coverage of regulation of gene expression in eukaryotes, where we have split our previous coverage into three parts: transcriptional regulation Chapter 17 , posttranscriptional regulation Chapter 18 , and epigenetic regulation Chapter Chapter 18 includes much of the content previously contained in the Special Topics chapter Emerging Roles of RNA in the previous edition.
Chapter 19, focused on epigenetics, is an expansion of the content previously contained in the Epigenetics Special. Topics chapter from the previous edition. Collectively, the addition of these four new chapters provides students and instructors with a much clearer, upto-date presentation to these important aspects of genetics. Continuing Pedagogic Features We continue to include features that are distinct from, and go beyond, the text coverage, which encourage active and cooperative learning between students and the instructor.
Appearing in many chapters, this feature prompts students to apply their analytical thinking skills, linking the experimental technology to the findings that enhance our understanding of gene function. It includes a section called Your Turn, which directs students to related resources of short readings and Web sites to support deeper investigation and discussion of the main topic of each essay.
Use of the Case Study should prompt students to relate their newly acquired information in genetics to ethical issues that they may encounter away from the course.
Since we cannot see genes, we must infer just what this unit of heredity is, based on experimental findings. Students are asked to review numerous findings discussed in the chapter and to summarize the process of discovery that was involved.
This feature places added emphasis on our pedagogic approach of conceptual learning.
