About This Chapter
Who's It For:
Anyone who needs help learning or mastering chromosomes material will benefit from the lessons in this chapter. There is no faster or easier way to learn about chromosomes. Among those who would benefit are:
- Students who have fallen behind in understanding chromosomes
- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning science (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about chromosomes
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources
How It Works:
- Find videos in our course that cover what you need to learn or review.
- Press play and watch the video lesson.
- Refer to the video transcripts to reinforce your learning.
- Test your understanding of each lesson with short quizzes.
- Verify you're ready by completing the Chromosomes chapter exam.
Why It Works:
- Study Efficiently: Skip what you know, review what you don't.
- Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
- Be Ready on Test Day: Use the Chromosomes chapter exam to be prepared.
- Get Extra Support: Ask our subject-matter experts any chromosomes question. They're here to help!
- Study With Flexibility: Watch videos on any web-ready device.
Students Will Review:
This chapter helps students review the concepts in a chromosomes unit of a standard cell biology course. Topics covered include:
- The genome
- Structure and physical features of chromosomes
- Chromosome condensation and DNA packaging
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. 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.
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. 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.
