Who's it for?
This chapter of our high school biology tutoring solution will benefit any student who is trying to learn about DNA and RNA and earn better grades. This resource can help students including those who:
- Struggle with understanding chemical structure of nucleic acids, complementary base pairing, double helix structure, types of RNA or any other DNA and RNA topic.
- Have limited time for studying
- Want a cost effective way to supplement their science learning
- Prefer learning science visually
- Find themselves failing or close to failing their Nucleic Acids: DNA and RNA unit
- Cope with ADD or ADHD
- Want to get ahead in high school biology
- Don't have access to their science teacher outside of class
Why it works:
- Engaging Tutors: We make learning about DNA and RNA simple and fun.
- Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
- Consistent High Quality: Unlike a live biology tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about nucleic acids on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Describe the chemical structure of nucleic acids.
- Explain complementary base pairing in DNA.
- Discuss the double helix structure of DNA.
- Understand the differences between DNA and 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: 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.
5. Base Pairs: Definition & Types
Nitrogenous bases pair with each other using hydrogen bonds. Learn how base pairs keep DNA together and how they help RNA take on useful shapes. Afterwards, you can test your knowledge with a quiz.
6. Cytosine: Structure & Definition
Cytosine is one of the bases that spell out genes in your DNA. It is so versatile that it's been called the 'wild card' of nucleic acids. Learn about the structure and functions of the letter 'C' in DNA's alphabet!
7. Hydroxyl Group: Definition & Structure
A hydroxyl group is a pair of atoms that is commonly found in organic compounds, such as sugars and alcohols. Learn more about the importance of this group and quiz yourself at the end.
8. Thymine: Structure & Definition
This lesson will describe the definition and structure of thymine as it relates to the formation of DNA. Also, there will be a small discussion about key facts that separate thymine from the other bases used to form the DNA helix.
9. Uracil: Definition & Structure
The overall structure of RNA and DNA consists of four nitrogenous bases that compose the backbone of their strands. One of these bases is known as uracil, and is found only in RNA. We will examine uracil's structure and function in this lesson.
10. What is Deoxyribonucleic Acid? - Definition & Structure
In this lesson, you will learn what deoxyribonucleic acid is and where it gets its name. Also this lesson will help you discover the major components and basic structure of deoxyribonucleic acid.
