Students will review:
This chapter helps students review the concepts in a nucleic acid unit of a standard high school biology course. Topics covered include:
- Chemical composition of nucleic acids
- Complementary base pairing
- Double helix structure in DNA
- Distinguishing between DNA and RNA
- Categorizing RNA
1. DNA: Chemical Structure of Nucleic Acids & Phosphodiester Bonds
In this lesson, you'll discover what nucleotides look like and how they come together to form polynucleotides. We'll also explore nucleic acids and focus on DNA in particular.
2. DNA: Adenine, Guanine, Cytosine, Thymine & Complementary Base Pairing
Learn the language of nucleotides as we look at the nitrogenous bases adenine, guanine, cytosine and thymine. Armed with this knowledge, you'll also see why DNA strands must run in opposite directions.
3. DNA: Double Helix Structure and Hereditary Molecule
This lesson will help you to navigate the twists and turns of DNA's structure. We'll also clue you in on the amazing discoveries that put this nucleic acid in the limelight as the molecule of heredity.
4. Differences Between RNA and DNA & Types of RNA (mRNA, tRNA & rRNA)
In this lesson, you'll explore RNA structure and learn the central dogma of molecular biology. Along the way, you'll meet the three types of RNA and see how the cell uses them most effectively.
5. Types of Nucleic Acids
This lesson addresses the types of nucleic acids and their structures. It contains illustrations and detailed descriptions about the various components that form these molecules. A summary and brief quiz are also included.
6. Guanine: Structure & Definition
One of the bases in DNA, guanine also does some cool jobs on its own. Learn about guanine's structure, functions, and the surprising origins of its name!
7. What Are Plasmids? - Definition, Types, Function & Characteristics
Learn about plasmids and how their DNA works to allow their host to adapt to harsh environments. Discover how plasmids are useful in modern-day genetic engineering.
8. What is DNA? - Structure, Overview
This lesson will explore the race to find the structure of the DNA molecule, the parts of that structure and how they fit together, and how this knowledge has been used to advance mankind.
9. Role of mRNA in Protein Synthesis
How does the message hidden within our DNA actually become something? This lesson discusses the vital role mRNA plays in protein synthesis. It helps explain how DNA is used within a living organism.
10. Role of Ribosomes in Protein Synthesis
Protein plays a huge role in our bodies, but how it is made? This lesson describes how ribosomes read the message hidden within our genetic code in order to produce protein. A lesson summary and brief quiz are included.
11. Role of tRNA in Protein Synthesis
This lesson takes a look at tRNA and its role in protein synthesis. It also includes some background on the process of protein synthesis itself and tRNA's interactions with other nucleic acids and enzymes.
12. What Is the Function of Protein Synthesis?
This lesson discusses the function of protein synthesis. We'll explore this very important process and some of the many roles it plays in sustaining life. At the end of the lesson, test your knowledge with a quiz.
13. What Is the Purpose of Protein Synthesis?
This lesson will cover the basic steps of protein synthesis. Once we review we'll look at some key examples of why protein synthesis is important in animals, plants and bacteria.
14. What Is the Role of DNA in Protein Synthesis?
What purpose does DNA serve inside the cell? How does DNA contribute to protein synthesis? Learn the answers to these questions and more in this lesson.
15. What Is the Role of RNA in Protein Synthesis?
This lesson discusses the role of RNA in protein synthesis. We'll define protein synthesis and explore how RNA contributes to this important cellular process, then you can test your knowledge with a brief quiz.
16. What Is the Site of Protein Synthesis?
Whether you are digesting food, fighting off disease, building muscle, or healing from a cut, protein plays a vital role. This lesson will introduce protein synthesis and explain where this process occurs.
