Ch 20: CEOE Middle Level Science: DNA Transcription & Translation

About This Chapter

Our CEOE Middle Level Science preparation course includes the DNA Transaction & Translation chapter. Our short, instructor-led video lessons will help you understand these topics as you prepare to pursue teacher licensure.

CEOE Middle Level Science: DNA Transaction & Translation- Chapter Summary

The DNA Transaction & Translation chapter of our CEOE Middle Level science exam study guide will first help you with the basics of DNA transaction and translation before going into a more comprehensive overview of these concepts. In this chapter, we have lessons on:

  • Protein synthesis
  • Copying DNA into RNA
  • Gene expression
  • The characteristics and role of an operon
  • Prokaryotic and eukaryotic cells
  • Peptide bonds
  • Elongation and initiation

By understanding the inherent concepts behind DNA transaction and translation, you'll not only be able to handle multiple-choice questions dealing with their basic principles with ease, but also apply them to more complex problems on the exam. The animated video lessons are led by experts and are easy to navigate. We'll help you understand the above concepts to better prepare you for your CEOE Middle Level Science examination.

Test your knowledge with a 30-question chapter practice test
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.

The Role of Ribosomes and Peptide Bonds in Genetic Translation

6. 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

7. 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.
