About This Chapter
NYSTCE Biology: Cell Cycle & Division - Chapter Summary
Use the lessons in this chapter to reinforce your understanding of the phases of the cell cycle and cell division processes. Key terms are defined and visual examples will help to support the learning experience. These lessons will address topics on which you will be tested when taking the Biology CST:
- Defining the genome
- Identifying structures of chromosomes
- DNA packaging and the cell cycle
- Explaining the processes of mitosis and cytokinesis
- Comparing sexual and asexual reproduction
- Detailing phases of reductional and equational cell division
- Discussing the cellular processes of autotrophs and heterotrophs
- Aneuploidy, adult stem cells and nondisjunction
Those who find visual presentations most helpful in learning or reviewing biology topics will find these lessons beneficial. The quizzes at the end of each lesson allow you to check what you have retained from the videos and see if you need to further review any specific topics.
NYSTCE Biology: Cell Cycle & Division Chapter Objectives
The Biology CST of the NYSTCE (New York State Teacher Certification Examinations) assesses your knowledge of and ability to teach students about cells, biochemistry, life processes, genetics, and evolution. The Cell Cycle & Division chapter will prepare you to answer questions on a portion of the second subarea of this test, 'Cell Biology and Biochemistry.' This subarea is worth 17% of the entire Biology CST.
The computer-based Biology CST combines 90 multiple-choice questions and a written assignment. The NYSTCE is a teacher certification exam; in addition to content area exams in such areas as chemistry, mathematics, physical education, social studies, and more, teachers can seek initial certification or certification in literacy or communication skills, performance, bilingual assessment, or teaching skills.
1. 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.
2. Chromosomes: Structure & Physical Features
You've probably heard about chromosomes before, but how much do you truly know about them? This lesson will discuss their structure and features and will go over all of the vocabulary you need to know to be a chromosome expert!
3. 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.
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. Overview of Mitosis: Mitotic Spindle & Phases of Chromosome Segregation
Have you ever wondered how we grow? We start off as tiny embryos that eventually develop into adult humans, but how? The answer is through mitosis. We will look at mitosis and some specifics of it here.
6. 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.
7. 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.
8. Overview of Reductional & Equational Cell Division in Meiosis
This lesson is going to give a general overview of the two divisions that take place during meiosis. We will take a look at why these divisions are referred to as reductional and equational division.
9. 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.
10. Embryonic and Adult Stem Cells: Uses, Origins & Properties
How can we grow a brand new windpipe? Or a heart? In this lesson, we'll learn about embryonic and adult stem cells and how scientists are using them to give people a new lease on life.
