About This Chapter
NYSTCE Biology: Genetic Mutations - Chapter Summary
This chapter has been put together to help you prepare for questions on the New York State Teacher Certification Examinations (NYSTCE) Biology exam. Learn about the types, causes and effects of genetic mutations. In this series of short lesson videos, our expert instructors will discuss:
- Penetrance and phenotypic variability of genetic disorders
- Types and effects of point mutations
- Environmental effects on mutation rates
Included with these lessons is a series of quizzes that will help reinforce what you've learned. You can use the video tags to jump between the lessons' main topics. A practice chapter exam will help you determine whether you understand genetic mutations well enough to correctly answer pertinent questions on the NYSTCE Biology exam.
NYSTCE Biology: Genetic Mutations Chapter Objectives
The NYSTCE Biology exam is used by the state of New York to measure future biology teachers' understanding of their field of study. This teacher certification exam is composed of 90 multiple-choice questions and one constructed-response question which are administered in a 240-minute session. These questions can be categorized into a series of subareas that include Cell Biology and Biochemistry. The section may feature questions about the implications of mutations.
1. Genetic Disorders: Penetrance & Phenotypic Variability
Did you know that sometimes a dominant human genetic condition will skip a generation in a family? It does happen, and some dominant genetic conditions will also have a wide range of phenotypes, sometimes even within the same family. Learn more in this lesson about phenotypic variability!
2. Point Mutations: Types, Processes & Effects
You might not think about your DNA that often, but you would probably notice if something was mutated on your DNA! This lesson will discuss what happens when your DNA gets mutated, focusing specifically on point mutations and their impacts.
3. Mutagens: How the Environment Affects Mutation Rates
What causes mutations to occur in living things? How do we avoid mutations? Are mutations always bad? Discover answers to these questions and more in this lesson on mutagens.
