Students will review:
In this chapter, you'll learn the answers to questions including:
- How does protein synthesis occur in the cell?
- What mechanisms do cells use to regulate gene expression?
- What is an operon and how does it function?
- How does RNA processing in eukaryotic cells occur?
- How does an RNA sequence translate into an amino acid?
- When does codon recognition occur during the translation process?
- What parts do peptide bonds and ribosomes play in genetic translation?
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. 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.
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.
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.
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.
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.
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.
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.
11. The Central Dogma of Biology: Definition & Theory
The central dogma of biology describes the flow of information from gene sequence to protein product. In this lesson, learn how the processes of transcription and translation work in cells, and discover how crucial sequence information is at every step.
12. What Is a Gene? - Definition & Structure
Genes are little codes found in our cells that make up who we are. This lesson covers where genes are located, how we get our genes, and the functions of genes.
