Essentials of Genetics is a guided introduction to many of the key concepts of genetics, from DNA structure and function to population genetics. Essentials of Genetics is an excellent reference for students or lifelong learners and teaching tool for faculty, featuring high quality video-based visualizations of genetics processes, clear explanations, and links to advanced study resources.
To better inform our decisions at the doctor, the grocery store, and at home, it is crucial for us to know something about genetics. As we cultivate this understanding, we need to explore the evidence that supports our modern knowledge of genetics. Scitable invites you to do so, throughout our Topic areas.
Cytogenetics is the study of chromosomes and their role in heredity. The articles in this room provide rich information on chromosome structure and composition, the methods that scientists use to analyze chromosomes, chromosome abnormalities associated with disease, the roles that chromosomes play in sex determination, and changes in chromosomes during evolution.
Evolutionary genetics examines the genetic relationships among groups of organisms and how changes in their genes shape the patterns of evolution and biodiversity. The articles in this room focus on five main areas: phylogenetics; mutation and molecular population genetics; the genetics of speciation; genome evolution; and evolution and development.
Gene expression and regulation describes the process by which information encoded in an organism's DNA directs the synthesis of end products - RNA or protein. The articles in this room explore the vast array of molecular and cellular processes and environmental factors that impact the expression of an organism's genetic blueprint.
Transmission genetics is the study of how genes are passed from one generation to the next. This articles in this room explore a wide range of topics in classical genetics. They also illustrate how the analytical power of gene inheritance combined with the molecular approaches covered in the other topic rooms help us to understand some of the most complex problems in genetics.
Understanding the role of genetics in disease has become a central part of medical research. As such, the articles in this topic room explore the complex relationship between human genetics and various disease states. This room examines current medical research and tools targeting these conditions in the effort to better treat or prevent them.
This topic room covers the ethical, legal, and social implications (ELSI) of genetic advances and their applications. To lay a foundation for ELSI discussions, this collection of articles explores the unique medical, ethical and legal issues encountered in genetic diseases, and the profound impact genetic conditions have at the individual, family, and societal levels.
A genome is an organism's complete set of genetic material. Thus, genomics is genetics on a huge scale, including information about vast numbers of genes and DNA sequences from scores of organisms. The articles in this room explore genomics-based methods for the study of genetic variation, the value of genomic data, and of course, the politics surrounding the uses of genomic data.
The articles in this topic room describe the science surrounding the structure and function of DNA. Here, you will find information on the chemical structure of DNA; organization of DNA into chromosomes, genes, and gene families; the processes of DNA replication, transcription, and translation; as well techniques related to manipulation of the genetic sequence.
Population and quantitative genetics focus on the genetic basis of variation among the individuals in a population. Population genetics focuses on allele and genotype frequencies, whereas quantitative genetics focuses on the ways that variation in genotype and environment contribute to variance in phenotype among individuals. The articles in this room address both subjects.
Spotlights are focused explorations of key topics in science: current issues in the news, emerging lab techniques, thought leader perspectives, governmental policy, and a range of other subjects. Spotlights provide an entry point into the rich and dynamic world of science.
No illness has dominated international headlines recently like the A-H1N1 virus, also known as the "swine flu." In early 2009, the emergence of A-H1N1 effectively shut down the Mexican economy and created widespread fear. By mid-2009, the virus had spread to become a global pandemic. How should the world's governments respond to this crisis?
The use of genetically modified organisms (GMOs) in agriculture dates back to the 1980s when the food industry sought new ways to increase the yield and durability of their crops. While GMO-based techniques are a valuable tool in the effort to decrease world hunger, some groups oppose their use because they believe that GMOs create harmful imbalances in the environment.
The use of stem cells in scientific research and medical treatments has sparked controversy because some stem cells are derived from human embryos. Nevertheless, the medical benefits derived from stem cell research are potentially significant. Should governments publicly fund stem cell research, as they fund many other kinds of therapeutic research? Should ethical concerns prevent scientists from conducting such research?
The use of synthetic drugs to enhance athletic performance, commonly referred to as doping, has exploded in recent decades. As newer methods for doping emerge, researchers must respond with tests capable of detecting them. This tug-of-war between dopers and testers has advanced the science of human physiology and drug testing significantly. Who is winning in this high-stakes competition?
