About This Chapter
MTEL Biology: Genetic Mutation, Variability and Engineering - Chapter Summary
Use the lessons in this chapter to refresh your memory about genetic mutation, variability and engineering as you prepare for the MTEL Biology Exam. The video lessons cover everything you are likely to be tested on, including:
- Human genetics and potential genetic abnormalities
- Variations and mutations in genes
- Definitions of genetic engineering and restriction enzymes
- Significance of DNA plasmids and ligase
Our experienced instructors guide you through all the topics, highlighting the important points so that you are prepared. By learning through different modalities, it becomes easier and more enjoyable to recollect what you need to know.
Objectives of the MTEL Biology: Genetic Mutation, Variability and Engineering
The MTEL Biology Exam is a standardized assessment instrument. It evaluates your comprehension of all the topics under the heading of 'Biology'. You need a passing score to be eligible for a teacher's license in the Commonwealth of Massachusetts. The topics in this Genetic Mutation, Variability and Engineering chapter are part of the Genetics, Evolution and Biodiversity Objective. There will be 17-19 multiple-choice questions on this objective. By completing the self-assessment quizzes that accompany the lessons, you can measure what you know and still need to learn and practice answering the types of questions you'll see on the test.
There are 100 multiple-choice and 2 open-response test items on the MTEL Biology Exam. The multiple-choice questions have you read a question or passage and choose the correct response from several presented to you. The open-response items evaluate your integration of biology knowledge by having you write two articulate, organized and logical essays on biological topics.
1. Human Genetics: Multifactorial Traits & Model Organisms
How do we study human genetics when most traits arise from multiple genes? It's certainly more complicated that drawing a simple Punnett square. Never fear, for model organisms are here!
2. Genetic Variability and Random Mutation
Evolution is driven by variation among populations. The amount of variability determines how well a population can adapt to environmental changes, while random mutations can provide new variations that help a population adapt to unexpected changes.
3. Genetic Abnormalities in Human Growth and Development
What are mutations and other chromosome abnormalities? How can these abnormalities affect human development? What are some common genetic disorders and their causes? Learn the answers to these questions in this lesson.
4. What is Genetic Engineering? - Definition and Examples
How do we make the insulin used by diabetic patients? In this lesson, you'll learn the basics of how genetic engineering can be used to transform a bacterial host cell into a genetically-modified organism that produces human insulin.
5. What is a DNA Plasmid? - Importance to Genetic Engineering
DNA plasmids play an integral part in most genetic engineering experiments. In this lesson, you'll learn about key features of a plasmid, such as a multiple cloning site, an origin of replication, and a selectable marker.
6. Restriction Enzymes: Function and Definition
Restriction enzymes played a critical role in the advent of genetic engineering. In this lesson, you will learn what role restriction enzymes play in creating recombinant DNA.
7. How Ligase is Used to Engineer Recombinant DNA
DNA ligase makes recombinant DNA technology possible. In this lesson, you will learn how new versions of genes can be designed for experiments in novel host organisms using DNA ligase.
