All About DNA

By: Kaleb Baker

What is DNA?

DNA- a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.

Everyone has DNA. It is on our bodies. DNA is made up of nucleotides (a building block of DNA), which we as humans also have. Its structure is a double helix formed by base pairs attached to a sugar-phosphate backbone.

What does DNA do?

DNA is all over our bodies. DNA is something that everyone has, everyone has different DNA, even from the same family.


Heredity is the passing of traits from one family member to the other.

Replication is the process of making two of the same DNA molecules.

Protein Production is the process of producing proteins.

What is RNA?

RNA (Ribonucleic Acid) is a polymeric molecule.


3 types of RNA are (mRNA) (tRNA) (Ribosomal RNA)


RNA carries information from DNA to the Ribosome.
