Ch 7: Developmental Mechanisms for the MCAT: Tutoring Solution

About This Chapter

The Developmental Mechanisms chapter of this MCAT Prep Tutoring Solution is a flexible and affordable path to learning about developmental mechanisms in cells. These simple and fun video lessons are each about five minutes long and they teach information involving developmental mechanisms required for the MCAT exam.

How it works:

  • Begin your review or other MCAT preparation work.
  • Identify the developmental mechanisms concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our MCAT Tutoring Solution will benefit any student who is trying to learn about developmental mechanisms and prepare for the exam. This resource can help students including those who:

  • Struggle with understanding cell fate, concentration gradients, how signaling molecules control differentiation, fate mapping or any other developmental mechanisms topic
  • Have limited time for studying
  • Want a cost effective way to supplement their MCAT preparation
  • Prefer learning science visually
  • Find themselves struggling with developmental mechanisms
  • Cope with ADD or ADHD
  • Want to get ahead in preparing for the MCAT
  • Need access to MCAT review materials

Why it works:

  • Engaging Tutors: We make preparing for the MCAT exam simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live MCAT prep tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Review developmental mechanisms on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Learning objectives

  • Learn how the cells in Spemann's organizer control cell fate.
  • Describe what roles inhibitors and signaling molecules play in development.
  • Discuss how signaling molecules manage differentiation.
  • Understand how fate mapping tracks development in cells.

Spemann's Organizer: Controller of Cell Fate

1. Spemann's Organizer: Controller of Cell Fate

Have you ever wondered how different parts of a developing embryo know what kind of tissue to become? What prevents two heads from developing on the same embryo, or for that matter, what ensures that a head develops at all? A small group of cells called Spemann's organizer determines the fates of the cells around them.

Concentration Gradients, Signaling Molecules & Inhibitors in Development

2. Concentration Gradients, Signaling Molecules & Inhibitors in Development

The discovery and characterization of Spemann's organizer was a significant achievement in the field of developmental biology, but this small piece of the dorsal lip is only the tip of the iceberg when it comes to coordinating the differentiation of all of the various tissue types in a growing embryo. In this lesson, you'll learn about concentration gradients and how they can be used to create various combinations of signaling molecules in different parts of the embryo.

How Signaling Molecules Control Differentiation

3. How Signaling Molecules Control Differentiation

From signaling molecules to transcription factors and gene expression, in this lesson you'll learn what it takes for a cell to differentiate. You'll also learn some of the ways a cell can make sense of different combinations of signaling molecules and how these combinations can be used to guide a cell through the process of differentiation.

How Fate Mapping Is Used to Track Cell Development

4. How Fate Mapping Is Used to Track Cell Development

Over the years, scientists have developed several methods to label and track groups of cells as they develop. These types of experiments are called fate mapping studies. In this lesson, you'll learn the basics of fate mapping and see how technology has allowed scientists to improve fate mapping techniques.
