Ch 3: The Transcription and Translation Process for the MCAT: Tutoring Solution

About This Chapter

The Transcription and Translation Process chapter of this MCAT Prep Tutoring Solution is a flexible and affordable path to learning about the transcription and translation process. These simple and fun video lessons are each about five minutes long, and they teach the information involving the transcription and translation process required for the MCAT exam.

How it works:

  • Begin your review or other MCAT preparation work.
  • Identify the transcription and translation process 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 prep tutoring solution will benefit any student who is trying to review the transcription and translation process and earn acceptable scores. This resource can help students including those who:

  • Struggle with understanding protein synthesis in the cell, regulation of gene expressions or any other transcription and translation process topic
  • Have limited time for studying
  • Want a cost effective way to supplement their MCAT preparation
  • Prefer learning MCAT topics visually
  • Find themselves struggling with the transcription and translation process portion of their review
  • Cope with ADD or ADHD
  • Want to get ahead in their MCAT preparation
  • Don't have access to MCAT review materials

Why it works:

  • Engaging Tutors: We make reviewing the transcription and translation process 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. Complete your transcription and translation process review 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:

  • Explore how central dogma relates to protein synthesis.
  • Learn the purpose of messenger RNA.
  • Find out the three phases of transcription.
  • See how organisms regulate gene transcription through transcriptional repression and induction.
  • Learn how operons control transcription in prokaryotic cells.
  • Review RNA splicing of introns and exons.
  • Explore the genetic code.
  • Find out how peptide bonds help create amino acid chains.
  • Learn about the steps of translation: initiation, elongation and termination.

Protein Synthesis in the Cell and the Central Dogma

1. Protein Synthesis in the Cell and the Central Dogma

Learn the story of the central dogma and how it relates to protein synthesis. We'll use a simple analogy to explore the roles of transcription and translation in building protein from the DNA code. In this lesson, we'll also introduce the concept of a gene.

Transcription of Messenger RNA (mRNA) from DNA

2. Transcription of Messenger RNA (mRNA) from DNA

In this lesson, you will gain a thorough understanding of how transcription works. We will investigate how DNA is transcribed into RNA with the help of a promoter and RNA polymerase. Learn the purpose of messenger RNA and explore the three phases of transcription.

Regulation of Gene Expression: Transcriptional Repression and Induction

3. Regulation of Gene Expression: Transcriptional Repression and Induction

Do our genes work the same way all the time? How do we regulate the expression of our genes? Explore the various ways organisms control gene transcription through repression and induction of operons.

How An Operon Controls Transcription in a Prokaryotic Cell

4. How An Operon Controls Transcription in a Prokaryotic Cell

Is gene regulation really as simple as flipping a switch? What are the parts of an operon, and how do they function to control gene transcription? We'll study the lac operon to answer these questions.

RNA Processing in a Eukaryotic Cell: Splicing of Introns & Exons

5. RNA Processing in a Eukaryotic Cell: Splicing of Introns & Exons

In this lesson, we'll explore the unique considerations for gene regulation in the eukaryotic cell. We'll walk through RNA splicing of introns and exons and the addition of the 5' cap and poly(A) tail.

What Is the Genetic Code That Translates RNA Into Amino Acids?

6. What Is the Genetic Code That Translates RNA Into Amino Acids?

How is RNA translated into a series of amino acids? Learn the language of the genetic code, explore a codon dictionary, and discover some basics of genetics in this lesson on translation.

Making Sense of the Genetic Code: Codon Recognition

7. Making Sense of the Genetic Code: Codon Recognition

Explore the genetic code and how it is translated into a polypeptide. We'll practice using the RNA codon chart and learn the basics of codon recognition.

Codon Recognition: How tRNA and Anticodons Interpret the Genetic Code

8. Codon Recognition: How tRNA and Anticodons Interpret the Genetic Code

How does codon recognition work at the molecular level? Can you use tRNA and anticodons to decipher the genetic code? Learn the mechanics of codon recognition and build a polypeptide from a sample genetic code.

The Role of Ribosomes and Peptide Bonds in Genetic Translation

9. The Role of Ribosomes and Peptide Bonds in Genetic Translation

Ribosomes play a major role in the process of genetic translation. In this lesson, learn about the structure of ribosomes and how peptide bonds help to create chains of amino acids.

Translation of mRNA to Protein: Initiation, Elongation & Termination Steps

10. Translation of mRNA to Protein: Initiation, Elongation & Termination Steps

Translation, the second part of the central dogma of molecular biology, describes how the genetic code is used to make amino acid chains. In this lesson, explore the mechanics involved in polypeptide synthesis. Learn the three major steps of translation as you watch tRNA, mRNA, and ribosomes go to work.

Transcription Factor: Definition & Identification

11. Transcription Factor: Definition & Identification

What is a transcription factor? Transcription factors are one of several ways cells regulate genetic expression. In this lesson we will cover how transcription factors were first identified and how they function.
