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. Phosphate Group: Definition & Explanation
This humble group of atoms (phosphorus surrounded by oxygen) can carry energy, shape your cell membranes, and help form the backbone of your DNA. Learn what a phosphate group is and how it does these important jobs.
