Ch 21: Nucleic Acids & Proteins

About This Chapter

Bring to mind what you know about nucleic acids and proteins by looking at this chapter. Before you take a biology exam, you need to feel secure in your knowledge of these topics, and our lessons can help build your confidence by giving you an extensive recap of biological processes and terms.

Nucleic Acids & Proteins - Chapter Summary

In this chapter, get acquainted with nucleic acids and proteins. Whether you need a quick review of vocabulary words or a thorough explanation of key concepts, use these lessons as your go-to resource. Our lessons describe the properties of nucleic acids and proteins, and the lessons will also review important related concepts.

As you make your way through the chapter, you will go over concepts like the necessity of proteins, the chemistry of proteins, and the structure of the DNA molecule. Our instructors also show you the roles of the various types of RNA. By completing the chapter, you will have gained the knowledge to do the following:

  • Describe the structure and function of nucleic acids
  • Identify the significance of the proteome and protein functional diversity
  • Determine the function and structure of proteins
  • Define peptide bonds, polymerization, and amino acids
  • Compare the characteristics and structure of the 20 amino acids
  • Explain the four orders of protein structures
  • Point out differences between DNA and RNA
  • Offer examples of the various types of polymerization

Before you commit to using our study materials, recognize that we hire only the most qualified instructors available. These are teachers who have thorough knowledge of biology concepts and related topics within the sciences. Our instructors also have years of experience as educators, so they know how to use different approaches to teach students of all levels.

Nucleic Acids: Function & Structure

1. Nucleic Acids: Function & Structure

In this lesson, we will explore what nucleic acids are, including the oozing bodily fluid they were first found in, what makes them unique from other types of biological molecules, and why DNA is called the 'blueprint of life.'

Protein Functional Diversity & the Proteome

2. Protein Functional Diversity & the Proteome

In this lesson, we'll be looking at the functional diversity of the proteome. We'll explore what the proteome is and some of the common functions seen across this diverse group of macromolecules.

Proteins I: Structure and Function

3. Proteins I: Structure and Function

We need our proteins, not just as a major food group but for the many useful roles that they play in our bodies. In our introductory lesson to proteins, you'll learn about the many functions we rely on them to perform.

Proteins II: Amino Acids, Polymerization and Peptide Bonds

4. Proteins II: Amino Acids, Polymerization and Peptide Bonds

In this lesson, we'll take a deeper look at amino acids. You'll learn what makes a peptide, and what separates a protein from other kinds of amino acid bonds.

Proteins III: Structure and Characteristics of the 20 Amino Acids

5. Proteins III: Structure and Characteristics of the 20 Amino Acids

How do amino acids form the intricate polypeptide chains found in proteins? It's a matter of chemistry. Join glycine, a special amino acid, as she sizes up the other amino acids.

Proteins IV: Primary, Secondary, Tertiary and Quaternary Structure

6. Proteins IV: Primary, Secondary, Tertiary and Quaternary Structure

How is progressing through higher order protein structures like crafting an essay? In this lesson, you'll explore everything from quaternary structures to denaturation as we show how the different structures are intertwined.

What is DNA? - Structure, Overview

7. 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.

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

8. 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.

What is Polymerization? - Definition, Types & Examples

9. What is Polymerization? - Definition, Types & Examples

In this lesson, learn about the process of polymerization. Explore the two major types, common polymers, and some of the chemistry involved with this biologically and commercially important chemical reaction.
