Ch 32: TExES Science 7-12: Nucleic Acids & Enzymes

About This Chapter

The Nucleic Acids & Enzymes chapter of our TExES Science 7-12 study guide and preparation course is your next step to succeeding on your exam. Our lesson plans are tailored to the TExES examination and feature short video lessons led by subject experts and self-assessment quizzes.

TExES Science 7-12: Nucleic Acids & Enzymes

In this chapter you'll review information about nucleic acids and enzymes. We'll go over their chemical structure, the difference between DNA and RNA, the function of enzymes and other topics. The Nucleic Acids & Enzymes chapter covers:

  • Chemical structure of nucleic acids and phosphodiester bonds
  • Adenine, guanine, cystosine, thymine and complementary base pairing
  • Double helix structure and hereditary molecule
  • Differences between DNA and RNA
  • Different types of RNA
  • The function of enzymes
  • Coenzymes, cofactors and prosthetic groups
  • Enzymatic reactions

Our expert instructors will help you prepare for the nucleic acids and enzymes topics you might come across on the TExEs Science 7-12, since our lesson plans are designed specifically with the test in mind. Plus, with our convenient video tags and accurate transcripts, you can learn at your own pace and never have to worry about missing any information.

DNA: Chemical Structure of Nucleic Acids & Phosphodiester Bonds

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.

DNA: Adenine, Guanine, Cytosine, Thymine & Complementary Base Pairing

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.

DNA: Discovery, Facts, Structure & Function in Heredity

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.

Differences Between RNA and DNA & Types of RNA (mRNA, tRNA & rRNA)

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.

The Function of Enzymes

5. The Function of Enzymes

Have you ever used a drill to accelerate building something that only requires a screwdriver? It went a lot faster, didn't it? In this lesson, you'll learn how that drill is a lot like an enzyme.

Coenzymes, Cofactors & Prosthetic Groups: Function and Interactions

6. Coenzymes, Cofactors & Prosthetic Groups: Function and Interactions

Some enzymes require helpers to recognize a substrate or complete a reaction. These helpers include cofactors, coenzymes, and prosthetic groups, which are required for some enzymes' functions.

Enzymatic Reactions: Inhibition and Regulation

7. Enzymatic Reactions: Inhibition and Regulation

Enzymes are generally not allowed to run uncontrolled in a cell. While they are useful in catalyzing reactions, there is a time and place for everything. In this lesson, we'll discuss enzyme activators and inhibitors that regulate these reactions positively and negatively, respectively.
