Protein Synthesis Transcription And Translation
Protein synthesis is defined as ââ¬Å"The creation of proteins by cells that uses DNA, RNA, and various enzymes.â⬠The synthesis of proteins takes two steps: transcription and translation. Transcription takes the information that is coded in DNA and codes it into mRNA, which heads out of the cellââ¬â¢s nucleus and into the cytoplasm. During translation, the mRNA works with a ribosome and tRNA to synthesize proteins. When trying to understand the process of protein synthesis, basic terms are necessary. DNA is the backbone of life as we know it. DNA stands for deoxyribonucleic acid and it is necessary to life on earth. The basic unit of DNA is called a nucleotide which is also known as a base. DNA is a double stranded helix that is made of these bases. DNA makes thousands of proteins using only four different basis. These bases are labeled as A, T, G, and C. These letters stand for adenine, thymine, guanine, and cytosine. These bases make pairs. A Pairs with T and G pairs w ith C.The same goes for RNA except thymine is replaced with uracil and RNA is single stranded. A continuous strand of DNA is called a gene. Genes are used to make functioning strands of RNA or proteins. The first step in protein synthesis is transcription which is when the cell makes an RNA copy of the information from DNA in the nucleus. The first step of transcription is called initiation. This is when the RNA polymerase binds to the promoter which contains the transcription start point. The polymerase bindsShow MoreRelated Protein Synthesis Essay772 Words à |à 4 PagesProtein Synthesis Protein synthesis is one of the most fundamental biological processes. To start off, a protein is made in a ribosome. There are many cellular mechanisms involved with protein synthesis. Before the process of protein synthesis can be described, a person must know what proteins are made out of. There are four basic levels of protein organization. The first is primary structure, followed by secondary structure, then tertiary structure, and the last level is quaternary structureRead MoreEssay about protien synthesis1605 Words à |à 7 Pages Protein Synthesis The Expression of a Gene nbsp;nbsp;nbsp;nbsp;nbsp;The process of Protein Synthesis involves many parts of the cell. Unlike other similar productions, this process is very complex and precise and therefore must be done in proper sequence to work effectively. The slightest error during this process could cause the action to experience difficulty or even fail. For example, in the production of starch, glucose molecules are combined to be stored and eventually utilized as usableRead MoreDna Is The Amazing Structure Known As A Double Helix910 Words à |à 4 Pagesbut also protein synthesis. Protein synthesis happens in the cytoplasm on the ribosomes. Transcription is the process of making an RNA copy of a gene sequence. This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes. Translation is the process of translating the sequence of a messenger RNA (mRNA, also the process of transcription), molecule to a sequence of amino acids during protein synthesisRead MoreGene expression is the process of protein formation. Proteins are the molecules that are900 Words à |à 4 PagesGene expression is the process of protein formation. Proteins are the molecules that are responsible for enabling us to live. They carry out majority of the processes that are important for life, as they include enzymes, transcription factors and the various cell machinery. Indeed, without proteins, life may not be a possibility. Gene expression cannot be carried out without a nucleic acid sequence, also known as DNA in humans. DNA is a double stranded molecule comprising of a sugar-phosphate backboneRead MoreGene Expression in Eukaryotes696 Words à |à 3 Pagesexpression in eukaryotes can be broken down into three stages. These stages include Transcription, RNA processing, and Translation. These steps are similar to gene expression in prokaryotes but RNA processing is specific to gene expression in eukaryotes. Transcription Transcription happens in the cell nucleus. This is where DNA can be found. For example you can use DNA as instructions to make certain things such as proteins, but, these instructions are in a different language and you do not understandRead MoreDescribe How Bacteria Decode Its Genetic Information to Produce Proteins?1510 Words à |à 7 Pagesits genetic information to produce proteins?
