Transcription
The first step that occurs is a process known as transcription. Here the information on the DNA is written down onto a different molecule called the RNA. This molecule acts as a messenger to carry the information to other parts of the cell.

Translation
The next step is called translation. In this step the cell organelles called ribosomes come into play. These ribosomes act as translators by translating the messenger's code into the proper protein format or a chain of amino acids that form the building blocks of the protein. Each amino acid is formed by combining three bases on the RNA.

Deoxyribonucleic acid (DNA) is the genetic code which ensures that daughter cells inherit the same characteristics as the parent cells
DNA is the code from which all protein is synthesised
All prokaryotes, eukaryote and some viruses have DNA
All DNA code is composed from four nucleotide bases, Adenine Cytosine, Guanine and Thymine.

DNA also contains all the genetic coding which is used to control functions, behavior and development of an organism. DNA is also used as a long term storage device to store the genetic instructions. These instructions must be correct so the DNA can make an exact copy of itself.
The function of DNA in a cell is to code the way proteins turn genes on or off.
the function of DNA is to make the proteins

DNA carries the codes for proteins. However, the actual protein differs a lot from the codes present on the DNA. The basic steps include:

Transcription
The first step that occurs is a process known as transcription. Here the information on the DNA is written down onto a different molecule called the RNA. This molecule acts as a messenger to carry the information to other parts of the cell.

Translation
The next step is called translation. In this step the cell organelles called ribosomes come into play. These ribosomes act as translators by translating the messenger's code into the proper protein format or a chain of amino acids that form the building blocks of the protein. Each amino acid is formed by combining three bases on the RNA.

Modification and folding
The third step is modification and folding and structuring of the final protein and sending it to the required areas in the body. ...more
