DeoxyriboNucleic Acid
4

It is found inside the cell of every living organism.
5
What does DNA do?

DNA Structure
A double helix (twisted ladder)
Sugar phosphate backbone
Nucleotides: ATGC
A and T connect
C and G connect

8
Amino Acids
"Building blocks" that when put together make proteins
There are 21 amino acids
9
DNA sends out RNA to outside nucleus
RNA (RiboNucleic Acid)
RNA is only 1 strand!
RNA then makes proteins, which helps build cells.
10
The difference in structure
RNA does not have AT, CG
What is not has is AU, CG
The T is replaced by U (Uracil)
