Learn about DNA base pairs. Discover the 4 bases of DNA and how they pair up, how many hydrogen bonds connect the two bases, and how RNA base pairings differ.

This lesson will explain nitrogenous bases, types of bases, and complementary base pairs in both DNA and RNA. It will also cover the rules of base pairing and provide examples.

Learn about the structure of DNA base pairs. Identify the molecular structure of DNA, study DNA diagrams, and discover the contributions of the Human Genome Project.

Learn about the DNA bases adenine, thymine, guanine, and cytosine. Discover which bases pair with each other, known as DNA complementary bases and what they do.

Learn all about DNA base pairs in this engaging video lesson. Understand their structure and specific pairings, followed by a quiz to test your knowledge.

Nitrogenous Base Pairs The nitrogenous bases connect in groups of two, called complementary pairs, using hydrogen bonds. Nitrogenous bases pair in this way because DNA is double-stranded.

Draw and label a short DNA segment with the following terms: nucleotides, base pairs, sugar-phosphate backbone, 3'-end, 5'end, phosphodiester bonds, and hydrogen bonds.

Learn how to write complementary DNA sequences, and see examples that walk through sample problems step-by-step for you to improve your chemistry knowledge and skills.

1. Complementary base pairing in DNA assures that only one of the following base pairs exists in DNA. Select the correct base pair.

If you want to pass this short quiz, you'll need to understand bases, bonds and the structure of DNA and RNA. Each question has a multiple-choice list of potential answers.
