TTC-Understanding Genetics-DNA Genes and their Real-World Applications
English | Size: 2.94 GB
We use it routinely to cure diseases, solve crimes, and reunite families. Yet we've known about it for only 60 years. And what we're continuing to learn about it every day has the potential to transform our health, our nutrition, our society, and our future. What is this powerful mystery?
It is DNA?deoxyribonucleic acid, the self-replicating material present in nearly all living organisms. Award-winning teacher, author, and cancer researcher Dr. David Sadava unlocks its mysteries in his new course, Understanding Genetics: DNA, Genes, and Their Real-World Applications. He guides us through decades of scientific discovery and the weighty implications for us, as individuals and as a society.
Genetics: The Science of Heredity
How are the traits of an organism?be it a fern or a human father?passed on to its offspring? This course outlines the history of the science of genetics and explains in detail what we have learned in recent decades about the building blocks?DNA.
Dr. Sadava, a working scientist who draws on examples from his own research, shows us how understanding genetics allows us to improve medical treatment and nutrition, vastly improving our health and quality of life.
Understanding genetics is also a critical step toward understanding our human identity. Examining our DNA?how it works and what happens when something goes wrong?enables us to see the roots of how our bodies work, why we get sick, and how traits are passed through families.
Enjoy this rare opportunity to peer over the shoulder of a working scientist; learn how he puzzles through the problems of genetics to find meaningful solutions that can save lives. Dr. Sadava shares cutting-edge research guided by his passion to help laypeople understand the meaning and importance of genetics.
Genetics' Long and Fascinating History
Our understanding of human development has certainly evolved since ancient Greek times, when Aristotle thought that the ingredients in semen were reorganized by menstrual fluid during intercourse to produce an embryo. And as late as the 17th century, Antonie Van Leeuwenhoek thought he saw tiny, fully formed babies when he looked under a microscope at sperm.
Other past civilizations, however, knew more about genetics than we might think. For example, Egyptians successfully bred the date palm 4,000 years ago to improve the quality and quantity of their fruit crop. In Asia and the Near East 3,500 years ago, horses were bred for speed in racing.
But while humans have worked to improve plant and animal characteristics for thousands of years, we've only come to truly understand what genes are made of and how they work during the past century.
