Biology 102: Basic Genetics is designed to be used to prepare for the Excelsior College Basic Genetics Exam. This course covers topics that are included on the exam, such as mitosis, meiosis, stem cells and genetic research. Use it to help you learn what you need to know about these topics to pass the Excelsior exam and earn real college credit.
The genetics instructors are experienced and knowledgeable science educators, who have put together comprehensive video lessons in categories covering a range of genetic-related material. Each category is broken down into short, engaging lessons that will cover topics more in-depth. These video lessons make learning fun and interesting. You get the aid of self-graded quizzes and practice tests to allow you to gauge how much you have learned so you can know when you're ready to take the Excelsior exam.
| Chapter | Objectives | |
|---|---|---|
| The Molecular and Chromosomal Basis of Inheritance | Study DNA and RNA, including replication, types and structure. Also learn about prokaryotic transcription, eukaryotic transcription, the genetic code and protein synthesis. | |
| Transmission/Mende Genetics | Examine an overview of genetics, properties of alleles, and Mendel's laws. Discover complementation tests, exceptions to simple dominance, polygenic traits, epistasis and heredity. | |
| Population Genetics and Evolution | Analyze the theory of evolution, the Hardy-Weinberg Equilibrium and natural selection. Investigate the ideas of inbreeding, genetic fitness and speciation. | |
| Model Organisms and Developmental Genetics | Learn about invertebrate and vertebrate model organisms and the pattern formation in the basic body plan. Study different types of genes, such as maternal-effect, gap, pair rule, segment polarity and homeotic. | |
| DNA Damage, Mutation and Repair | Examine what causes mutations, including mutagens and irradiation. Also look at DNA base excision repair. | |
| Human Genetics | Explore human genetics research that touches on topics, including pedigrees, population genetics and genetic disorders. Study topics related to sex chromosomes and genetic testing. | |
| Genomics and DNA Technology | Review topics related to comparative genomics, such as homology, prokaryotes, eukaryotes and chromosomes. Explore the polymerase chain reaction, cloning, genetic modification and the Human Genome Project. |
