PBS DNA Keychain - What is a Nucleic Acid? Nucleotide? Nitrogenous base?

Nucleic acids are large biomolecules that allow organisms to transfer genetic information from one generation to the next.


There are two types of nucleic acids:
  1. deoxyribonucleic acid (better known as DNA) and 
  2. ribonucleic acid (better known as RNA). 
Nucleic Acids:  Nucleic acids are composed of nucleotide monomers linked together.

Nucleotides contain three parts:
  1. A Nitrogenous Base 
  2. A Five-Carbon Sugar 
  3.  A Phosphate Group 

Nucleotides are linked together to form polynucleotide chains. Nucleotides are joined to one another by covalent bonds between the phosphate of one and the sugar of another. These linkages are called
phosphodiester linkages. Phosphodiester linkages form the sugar-phosphate backbone of both DNA and RNA. 

Adenine = B4!!  These include vegetables, Brewer’s yeast, eggs, fresh fruits, whole grains in breads and oats, + raw honey

Humans are suppose to eat
  • Carbohydrates
  • Proteins
  • Fats
  • Nucleic Acids  helps make DNA, RNA and ATP when linked with ribose
