Students will review:
This chapter helps students review the concepts in a cell division unit of a standard AP Biology course. Topics covered include:
- The genome
- Chromosomal characteristics and structure
- DNA packaging
- Mitosis and meiosis
- Aneuploidy and nondisjunction
1. Basic Genetics: The Genome & Chromosomes
Genomes are the DNA content of a cell, and DNA is organized into chromosomes. Learn about basic genetics, such as genomes and chromosomes, gametes, homologous chromosomes, and diploid complements.
2. How is DNA Organized into Chromosomes? - Structure & Function
DNA is organized into chromosomes and even further organized within those chromosomes. Explore the structure of chromosomes, the function of DNA, and learn about genes and their role in DNA.
3. The Cell Cycle: Definition, Phases & Sequence
The lifetime of a cell is described as the cell cycle. Learn about the definition of the cell cycle and explore the phases and sequence of the cell cycle.
4. How is DNA Packaged? - Chromosome Condensation & Karyograms
Discover how DNA is packaged by understanding how chromosomes condensation and karyograms work. Explore DNA packaging, cell division, histone modification, chromatin packaging, and karyograms.
5. Parts of a Chromosome & Their Roles
Chromosomes are made of a number of multiple parts with different roles. Learn about the parts of a chromosome and their function, including the centromere, chromosomal arm, and telomere.
6. Mitotic Spindle: Definition, Formation & Function
Explore the definition of mitotic spindle as well as its formation and function. Learn about the parts of the mitotic spindle, including microtubules, centrosomes, astral and kinetochore microtubules, and chromosome movement.
7. Stages of Mitosis: Description & Sequence
Mitosis is a continuous process with five different stages: prophase, prometaphase, metaphase, anaphase, and telophase. Explore detailed descriptions of the different stages of mitosis.
8. Cytokinesis: Animal Versus Plant Cells
Cytokinesis is a natural process that occurs when a plant or animal cell is divided into two new daughter cells. The process is constantly repeated to create new cells. Learn about cytokinesis and the difference between animal cell division and plant cell division.
9. Asexual vs. Sexual Reproduction: Comparison & Characteristics
Organisms reproduce in two indifferent ways. Explore a comparison of the characteristics of asexual versus sexual reproduction and discover the differences between mitosis and meiosis.
10. Meiosis: Comparison to Mitosis, Crossing Over & Process
Meiosis and mitosis describe the processes in which cells divide to create new cells. Learn about the similarities and differences between meiosis and mitosis, meiotic recombination, and the various stages of meiosis.
11. Meiosis I Stages: Prophase I, Metaphase I, Anaphase I & Telophase I
In Meiosis I, the number of chromosomes in cells is reduced by one-half. Learn about the different stages of Meiosis I, including Prophase I, Metaphase I, Anaphase I, and Telophase I.
12. Meiosis II: Definition, Stages & Comparison to Meiosis I
Learn about the definition and stages of meiosis II and how it compares to meiosis I. Compare the types of cell division during meiosis I with that of meiosis II, and take a closer look at the five stages of meiosis II.
13. Nondisjunction & Aneuploidy: Definition & Examples
Nondisjunction occurs when homologs or chromatids fail to separate during a phase of mitosis or meiosis, while an aneuploidy is a cell with an abnormal number of chromosomes. Explore the definitions and find examples of nondisjunction and aneuploidy.
14. Centrosome: Definition & Function
Within a cell, structures such as centrosomes have several purposes and functional responsibilities in cellular function. Learn about the definition of centrosomes, their role and function in cell division, and some useful vocabulary.
15. Sister Chromatids: Definition & Concept
Sister chromatids play a very important role in mitosis. Understand the definition and concept of sister chromatids; examine the difference between chromatin, chromosomes, and chromatid; chromatids vs. homologous pairs; and explore sister chromatids in mitosis and meiosis.
16. Chromosome Banding: Definition & Techniques
Here we will discuss what chromosome banding is. We will also look at several different types of chromosome banding, techniques for chromosome banding, and why one would want to perform chromosome banding.
