DNA and RNA are used to direct the activity of cells.

Cells look and function a certain way because of directions contained in the DNA.

They have 3 Parts:

Here is what they look like all put together:

Nucleic acids are linked together to form long chains, and DNA is made of two parallel chains:

These parallel chains have a twist to them so DNA is often called a Double Helix.

Making DNA molecules:
