Introduction

Biochemical techniques DNA to Protein Introduction On this essay I will explain how Deoxyribonucleic acid DNA, stores all of our genetic information and the processes of transcription and translation which expressed genetic information. DNA is an extremely long slim macromolecule made up of many different deoxyribonucleotide subunits. Each DNA molecule is made up of two very long polymers linked by hydrogen atom and coiled in the shape of a double helix. Each of this two polymers contain many structures called nucleotide. Which broken down in three parts: deoxyribose ( a five carbon sugar) a phosphate group and a nitrogenous base. There are four crucial different nitrogenous bases that present in DNA: thymine, cytosine, adenine and guanine. These bases are the foundation of the genetic code. Sometime represented as T, C. A. G. this bases always pair up in the same way, adenine forms a bond with Thymine and cytosine bonds with guanine as shown in the below diagram. ...read more.

The sequence of these nucleotides that determines the sequence of amino acids and the protein that is being assembled by the ribosome.[2] This different from of RNA work together in living organism to synthesis protein, messenger or mRNA is a copy of the information carried by a gene of the DAN and the role of mRNA in the cell is, to move the information contained in DNA to the translation machinery. Transfer RNA (tRNA) synthetases play a major role in translation during protein synthesis working as adaptor by recognize a triplet on the mRNA through a region called an anticodon and carry a covalently attached amino acid corresponding to that triplet in the genetic code. Since there are three bases and four possible nucleotides there can be up to 64 (4x4x4) possible tRNA molecules. Ribosomal RNA is the central component of the ribosome. The function of rRNA in protein synthesis is to provide a mechanism for decoding mRNA into amino acids and to interact with the tRNA during translation by providing peptide activity. ...read more.

Conclusion

Ribosomes are made of a small and large subunit which surrounds the mRNA. In translation messenger RNA ( mRNA) decoded to produce a specific polypeptide according to the rules specified by the genetic code. During this process the use of mRNA sequence is to guide the synthesis a chin of amino acid that form a protein. Translation proceeds in four phases: activation. Initaiation, enlogation and termination. Generally, one of the primary function of RNA is to facilitate the translation of DNA into protein. And also transfer the genetic code need for the creation of protein from the nucleus to the ribosome. This process prevents the DNA from having to leave the nucleus, so it stays safe. Without RNA proteins could never be made. [3] Reference: 1) Advanced Biology for you. Michael Roberts; Michael Reiss, Grace Monger.
