OAE - Biology: Cell Division - Chapter Summary
These video lessons cover cell division in an engaging and easy-to-follow format to make it easier for you to get up to speed for the OAE Biology exam. Once you've finished this chapter, you will be able to:
- Define binary fission and list its steps
- Understand the many characteristics of a genome
- Chart the structure of chromosomes
- Differentiate asexual reproduction from sexual reproduction
- Describe the sequences of the cell cycle
- Explain DNA packaging and the transformation that chromosome condensation causes
- List the physical aspects of a chromosome
- Communicate the role and process of mitosis
- Distinguish between cytokinesis in animal and plant cells
- Understand meiosis
- Depict how reductional and equational cell division differ
- Characterize the defects caused by nondisjunction and aneuploidy
Our instructors utilize diagrams and other visual aids to help familiarize you with cell division. Take a gander at the helpful video lessons they've organized, and then test yourself with our multiple-choice assessment quizzes.
OAE - Biology: Cell Division - Chapter Objectives
For teaching candidates and teachers whose licenses are set to expire in Ohio, earning a passing score on the OAE exam for their subject area is required. Life science classes for 7th graders and older can only be taught by those who have scored a 220 OAE Biology exam.
The Biology OAE contains five domains, each focused on a different content area. You have three hours to complete the multiple-choice test. The biochemistry and cell biology section, which covers 13% of the 150 questions on the Biology OAE, includes questions about cell division. Get an idea of what to expect for these questions with our lesson quizzes and chapter exam.
1. Binary Fission: Definition, Steps & Examples
Bacteria are all around you, some make you sick, some are helpful. This lesson will examine one way bacteria reproduce called binary fission. It will also give you some examples of bacteria you may encounter.
2. Basic Genetics: The Genome & Chromosomes
There are approximately 3 billion bases in the human genome. In this lesson, you'll learn more about the genome and its organization into chromosomes. We think about DNA often as the blueprint for life, but we can also think of it as the recipe for life with the nucleus being the library.
3. How is DNA Organized into Chromosomes? - Structure & Function
Explore the structure of chromosomes and see how DNA fits inside the nucleus of the cell. In this lesson, you'll learn about histones, chromatin and nucleosomes.
4. The Cell Cycle: Definition, Phases & Sequence
Learn about the dividing and non-dividing states of the cell and discover the different phases of the cell cycle, including interphase, cytokinesis, and the stages of cell division.
5. How is DNA Packaged? - Chromosome Condensation & Karyograms
Learn how DNA packaging makes it possible to fit approximately seven feet of DNA inside a single cell. You'll see how chromosome condensation helps cells get ready for cell division.
6. Parts of a Chromosome & Their Roles
Learn all about chromosomes, including the different parts of a chromosome and the types of chromosomes in diploid organisms like humans. Learn the vocab used with chromosomes.
7. Mitotic Spindle: Definition, Formation & Function
Condensation makes DNA ready / And microtubules hold it steady / A microtubule's a fancy rope / To move the DNA is the hope / From spindle poles they do extend / To align each chromosome in the end
8. Stages of Mitosis: Description & Sequence
Let's take a second look at mitosis and focus on the phases of chromosome segregation. As we concentrate on chromosomes, you'll learn the tricky dance that takes place through all five phases of mitosis.
9. Cytokinesis: Animal Versus Plant Cells
What's a cell to do when it must divide in two? We'll explore cytokinesis and see how the process can differ in important ways when it comes to plant versus animal cells.
10. Asexual vs. Sexual Reproduction: Comparison & Characteristics
Did you know that some organisms can reproduce without a mate? Check out this video lesson on asexual versus sexual reproduction to discover the different ways organisms can reproduce and the main differences between mitosis and meiosis.
11. Meiosis: Comparison to Mitosis, Crossing Over & Process
Welcome to meiosis, a realm of division doubled for reproduction untroubled. You'll get a preview of both divisions of meiosis and see what it takes to go from a diploid cell to a haploid gamete.
12. Meiosis I Stages: Prophase I, Metaphase I, Anaphase I & Telophase I
How does meiosis keep track of homologs and reduce the genome by half? Know these answers and more as we navigate the steps of meiosis I. This lesson will be tetradical!
13. Meiosis II: Definition, Stages & Comparison to Meiosis I
Behold round two of meiotic cell division! You'll see how meiosis II keeps the genome intact and gives the final push to produce haploid gametes, which make the world go round.
14. Nondisjunction & Aneuploidy: Definition & Examples
Learn why proper chromosome segregation is essential during meiosis. We'll see how having an extra chromosome can lead to Down Syndrome and also examine the consequences of having too few chromosomes. Disruptions to the delicate balance of cell division can have far-reaching effects.
