DNA

DeoxyriboNucleic Acid

What is DNA?

DNA carries all the genetic information of an organism.

It is found inside the cell of every living organism.

What does DNA do?

DNA helps make proteins

It tells your cells what to do.

It also determines the genes passed down to offspring.

DNA Structure

A double helix (twisted ladder)

Sugar phosphate backbone

Nucleotides: ATGC

A and T connect

C and G connect

Amino Acids

"Building blocks" that when put together make proteins

There are 21 amino acids

DNA sends out RNA to outside nucleus

RNA (RiboNucleic Acid)

RNA is only 1 strand!

RNA then makes proteins, which helps build cells.

The difference in structure

RNA does not have AT, CG

What is not has is AU, CG

The T is replaced by U (Uracil)
