OAE - Biology: Protein Synthesis- Chapter Summary
Utilize these video lessons to get a better understanding of protein synthesis and its relationship to DNA, RNA, and amino acids within the body. Enjoy these videos as many times as you like until you know DNA and RNA like the back of your hand. Soon, you will be ready to:
- Define the central dogma of protein synthesis
- Describe the process of transcription from DNA to messenger RNA
- Examine how gene expression is regulated
- Detail the splicing of introns and exons in eukaryotic cells
- Understand the genetic code used to transform RNA into amino acids
- Comprehend how tRNA and anticodons translates the genetic code
- Explain the purposes of ribosomes and peptide bonds
Each video was put together by one of our expert instructors, each of whom specializes in making complex information like protein synthesis easy to understand. Study from your computer, tablet, phone, or any other mobile device. Try out our self-assessments to get a feel for the types of questions you'll encounter on the OAE Biology test.
OAE - Biology: Protein Synthesis - Chapter Objectives
For Ohio educators seeking licensure to teach biology, passing the Ohio Assessments for Educators (OAE) Biology exam is a prerequisite. The exam is made up of five content domains, each one focused on a different area of biology. This study guide is set up to prepare you for questions about protein synthesis in the genetics and evolution section content domain. This section covers 27% of the test. You have 180 minutes to complete the 150 multiple-choice questions on the entire OAE Biology exam.
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.
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.
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.
4. 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.
5. 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.
6. 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.
7. 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.
