Steps Of Protien Synthesis

Protein synthesis is the steps taken to create a protein. It starts in the nucleus of the cell. The double helix of DNA is ripped open in half by helicase and the free floating nucleotides for RNA come in and create messenger RNA or mRNA, for a specific section or gene of DNA. mRNA is made up of adenine, cytosine, guanine and uranine. The mRNA then travels outside of the nucleus and meets up with ribosomal RNA aka rRNA. This is more commonly known as a ribosome. The rRNA "reads" the mRNA and for every three bases on the mRNA it finds the complimentary bases on the tRNA (transfer RNA). The tRNA carries amino acids which connect into a chain as the rRNA continues reading the mRNA. When the mRNA tells the rRNA to stop reading it, the rRNA breaks off leaving a string of amino acids which then fold up into a protein.
