Nucleic Acids

Largest molecules made by organisms. They store the info a cell needs to make proteins.

1. DNA- Genetic material. Template for all proteins. Controls RNA.

2. RNA- Smaller genetic material. Directs protein synthesis.


Nucleic acids contain both nitrogen (N) and phosphorus (P) which helps to identify them.

Nucleotide: The building block of all nucleic acids. You put many nucleotides together to make DNA. All nucleotides are made of 3 parts, a phosphate molecule (P), a 5 carbon sugar, and a nitrogen base. The nitrogen base provides the genetic code.

The diagram below shows a nucleotide in its molecular form. Nucleotides are building block forms of all nucleic acids.
