Who's it for?
This chapter of our college microbiology tutoring solution will benefit any student who is trying to learn biology basics and earn better grades. This resource can help students including those who:
- Struggle with understanding DNA, RNA, biological molecules, isotopes, cell transport or any other basic biology topic
- Have limited time for studying
- Want a cost effective way to supplement their biology learning
- Prefer learning biology visually
- Find themselves failing or close to failing their biology review unit
- Cope with ADD or ADHD
- Want to get ahead in microbiology
- Don't have access to their biology teacher outside of class
Why it works:
- Engaging Tutors: We make learning biology basics 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 microbiology tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn biology basics for microbiology on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Learn the chemical structure of nucleic acids and phosphodiester bonds.
- Explain complementary base pairing in DNA.
- Describe the double helix structure of DNA.
- Explain the differences between DNA and RNA.
- Understand the functions of enzymes.
- List the major elements of biological molecules.
- Discuss the relationship between isotopes and average atomic mass.
- Learn how to track biological molecules using radioactive isotopes.
- Understand active and passive transport in cells.
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. Function of Enzymes: Substrate, Active Site & Activation Energy
In this lesson, we'll learn how enzymes function to lower the activation energy of a chemical reaction. Enzymes bind to their substrates to perform all kinds of important and essential cellular processes, as well as processes that help you enjoy a slice of pizza!
6. Major Elements in Biological Molecules: Proteins, Nucleic Acids, Carbohydrates & Lipids
Bacterial cells have complex macromolecules built from simple molecules. In this lesson, we will look at the major elements in the building blocks of proteins, nucleic acids, carbohydrates, and lipids.
7. Isotopes and Average Atomic Mass
When you drink a glass of water, you are actually drinking a combination of heavy water and light water. What's the difference? Is it harmful? This video will explain the difference between the two types of water and go into detail on the significance of the different isotopes of elements.
8. How Radioactive Isotopes Track Biological Molecules
Radioactive isotopes can be used to track atoms and label biological molecules. This lesson explores how this can be applied to microbiology to learn more about the way a cell works.
9. Passive Transport in Cells: Simple and Facilitated Diffusion & Osmosis
A cell membrane is selectively permeable - not permeable to everything. In this lesson, we'll talk about methods of passive transport along a concentration gradient, including simple and facilitated diffusion and osmosis.
10. Active Transport in Cells: Definition & Examples
In this lesson, we'll learn how substances are transported across the cell membrane against the concentration gradient. This might seem like an uphill battle for the cell, but all it takes is a little chemical energy and a few integral membrane proteins to kick off some active transport!
11. Macromolecules: Definition, Types & Examples
In this lesson you will explore macromolecules. You'll be interested to learn that these very large molecules are made up of smaller 'building block' units, and that they are in plastics, textiles, and even in you!
12. What Are Chromosomes? - Definition, Function, Types & Structure
In this lesson, you'll find out why primates look so human while learning about the different types of chromosomes and how they work. You'll also get a chance to see what a chromosome looks like and discover how many genes are found in the human body.
