About This Chapter
TExES Life Science: Nucleic Acids - Chapter Summary
This chapter offers a look at biological molecules, including DNA and RNA. You'll re-examine their structural components and analyze the differences between these two nucleic acids. The video lessons in this chapter will also allow you to review the functions of nucleotides and pyrimidines. When you use the lessons as study tools, you can become better-prepared to take the TExES Life Science examination. The chapter might help you with:
- Explaining the chemical composition of phosphodiester bonds and nucleic acids
- Understanding complementary base pairing
- Discussing the functions of guanine, cytosine, thymine and adenine
- Discussing double-helix structure and the hereditary molecule
- Comparing the structural components of DNA and RNA molecules
Well-educated lesson instructors outline the fundamentals of nucleic acids so that you can address the material with confidence when you sit for the TExES Life Science examination. The lessons are designed to be informative and user-friendly. You can study anywhere as long as you have access to Web-ready technology. Use the video tags to locate information right away and submit your questions on nucleic acids to the experts. Take the self-assessment tests to gauge your progress.
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: Discovery, Facts, Structure & Function in Heredity
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.
