Ch 9: Genetic Mutations: Help and Review

About This Chapter

The Genetic Mutations chapter of this College Biology Help and Review course is the simplest way to master genetic mutations. This chapter uses simple and fun videos that are about five minutes long, plus lesson quizzes and a chapter exam to ensure students learn the essentials of genetic mutations.

Who's it for?

Anyone who needs help learning or mastering college biology material will benefit from taking this course. There is no faster or easier way to learn college biology. Among those who would benefit are:

  • Students who have fallen behind in understanding the causes and effects of different genetic mutation types
  • 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 genetic mutations
  • 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 Genetic Mutations 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 Genetic Mutations chapter exam to be prepared.
