deoxyribonucleic acid


DNA is a self-replicating material in nearly all living organisms. It is located in the nucleus of the cell. DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide includes nitrogen-containing nucleobase—either guanine (G), adenine (A), thymine (T), or cytosine (C) also a deoxyribose and a phosphate group. The structure of DNA is a double helix formed by base pairs.
DNA is used to make proteins. Proteins are the complex molecules that do most of the work in our bodies.

Heredity- Passing of traits to offspring from its parents.
DNA Replication- Process of producing two identical replicas from one original DNA molecule.
Protein Production- A few genes produce other molecules that help the cell assemble proteins.


RNA is a nucleic acid that is generally single stranded and plays a role in transferring information from DNA to protein-forming system of the cell. There are three types of RNA including; mRNA- messenger RNA, tRNA- transfer RNA, and rRNA- ribosomal RNA. RNA serves for the purpose of making proteins for any part of the body in need.
