What is DNA

• Deoxyribonucleic Acid

• Made of:

  • Phosphate groups

  • Deoxyribose sugars

  • Nitrogenous Bases

• A series of nucleotides creates a long-stranded molecule

• Code for ALL life; from us to the bacteria that make us sick!

• ​Molecule resides in the nucleus of eukaryotic cells and freely float in prokaryotic cells

​

What is DNA?

Each nucleotide contains a Phosphate, sugar, and nitrogenous base.

​Some text here about the topic of discussion.

What is a nucleotide?

These alternate to form the ladder-like backbone of DNA​

What does the sugar and phosphate group do?

Nitrogenous bases are the "code" part of DNA and/or RNA. Their order is what tells the cell what to make and how to do it. 4 bases found in DNA; in RNA U replaces T.

BASES include:

Cytosine

Thymine (DNA ONLY!)

Guanine

Adenine​

​ Uracil (RNA ONLY!!)
