Compare And Contrast Rna And Anti-Codons

3) As a ribosome moves along the mRNA, the genetic message is translated into a protein with a specific amino acid sequence.

Transcription is the formation of an RNA strand from a DNA template within the nucleus of a cell. There are four nucleotides of DNA. These are adenine, cytosine, guanine and thymine. These nucleotides are transcribed to form messenger ribonucleic acid (mRNA) consisting of nucleotides made of adenine, cytosine, guanine and uracil. This transcription from DNA to mRNA happens by an RNA polymerase II. This newly created mRNA is read in the 5' to 3' direction in sets of 3. These sets are called codons. Each mRNA also has a cap and end. On the 5 prime side is a methylated guanine triphosphate and on the 3 prime is a poly A tail. Messenger RNA then moves to the cells cytoplasm and through the cells ribosomes for translation. Messenger RNA is matched to molecules of transfer RNA (tRNA) in the ribosomes to create amino acids. These amino acids subsequently form an amino acid chain. (Osuri, 2003) A visual representation of this can been viewed in figure 3.

The four nucleotide of RNA are Adenine and Uracil, Guanine and Cytosine. 18. You can find DNA in the nucleus of a cell. DNA contains all the information that is needed to produce proteins. 19.

Since DNA has the instructions for making protein we usually wonder how is it able to make ribosomes if DNA is stored within the nucleus. This is when a handy tool comes in called transcription and copies the DNA into mRNA so it can be reached outside of the cell.

Transcription is the process of using DNA to make template RNA strain. RNA polymerase is one the most important enzyme for transcription which happens inside of the nucleus. This enzyme binds to DNA by a promoter and unwinds DNA into 2 separate strands such as template strand and coding strand. RNA polymerase moves along the template strand, copying one strand into a molecule of RNA. The enzyme is transcribed until it hits a stop codon, then the RNA strand releases from the DNA and the transcription ends.

Transcription is where I translate the list of nitrogenous bases in the mRNA at the cell's ribosomes. I want to tell you what a codon is and tell you my five other journeys. A codon is where each three nitrogenous bases in an mRNA that helps a specific amino acid added to me the protein butterfly. My adventure begins when a ribosome comes together to an mRNA in the cell's cytoplasm. Then on my journey my BFF codon goes throught the ribosome, tRNA shares with the amino acid to the ribosome. My other friend anticolon does a great job of putting three nitrogenous bases in tRNA to help the codon in mRNA. My third adventure was where tRNA bring a type of amino acid; then she breaks the code in the mRNA into a guide of amino acids. Following is my second to last adventure was when my friend ribosome and rRNA makes the amino acid together. My last adventure was the funnest because this is the part where I turned into a protein butterfly. :) Here is how the ending goes: My other friend protein chain goes raises til the ribosome gets a end codon on the rRNA. After that ribosome leaves equally mRNA and me the protein

Transcription is a process in which genetic information from DNA is encoded onto messenger RNA, by unwinding the DNA and splicing exons and introns and coding them onto the mRNA so the DNA itself is not used directly. Translation is a process by which ribosomes reads the mRNA to determine the amino acid sequence of the protein.

Compare and contrast DNA and RNA. Discuss why humans did not evolve with one central repository of DNA, but rather it is replicated throughout the body?

Inside each and every cell in your body is a strange chemical called deoxyribonucleic acid, better known as DNA. DNA is a double-helix structure that is made up of billions of nucleotides. They are adenosine, thymine, cytosine, and guanine, abbreviated A, T, C, and G, respectively. “The information content resides in those chemical bases arranged within the interior, where A always pairs with T, and C always pairs with G” (Collins 6). These base pairs are lined up in a pattern as rungs on the DNA “ladder”. A gene is a section of base pairs in the strand of DNA. The smallest genes span about a few hundred base pairs, and the largest

Transcription is where DNA is transcribed into RNA which then can be pass to the ribosome’s to act as a template for protein synthesis. Before transcription can begin DNA must unwind and the two halves of the molecule much come apart so exposing the base sequence. This process begins when a region of a two DNA strands is unzipped by enzyme called RNA polymerase attaches to the DNA molecule at the imitation site.

The formation of a protein begins in the genes, which contain the basic building information for all parts of living organisms. There are four DNA nucleotides that make up genes: A, T, C, and G. A codon is any arrangement of three of these nucleotides. Each triplet of nucleotides codes for one amino acid. First transcription will begin in the nucleus where mRNA will transcribe the DNA template. During both transcription and translation, there are three steps. The first step in transcription is initiation where RNA polymerase separates a DNA strand and binds RNA nucleotides to the DNA. RNA nucleotides are the same as DNA ones except that U replaces the T. The second is just the elongation of the mRNA. The third step of transcription is termination. This occurs when RNA polymerase reads a codon region and the mRNA separates from the

material of some viruses. RNA molecules are like DNA. They have a long chain of

Illustrated in figure 2 is transcription, which is broken down into three stages. First the RNA polymerase binds to the DNA at a promoter region, this promoter region contains sequences which allow binding of the RNA polymerase. The second stage of transcription is elongation, as the DNA is unwound the RNA polymerase forms the singled stranded mRNA molecule. Like with DNA, the RNA is made of nucleotide bases with the exception that instead of thymine there is uracil. As the RNA polymerase forms the mRNA, complementary bases pair up guanine with

Protein Synthesis Protein Synthesis is the process whereby DNA (deoxyribonucleic acid) codes for the production of essential proteins, such as enzymes and hormones. Proteins are long chains of molecules called amino acids. Different proteins are made by using different sequences and varying numbers of amino acids. The smallest protein consists of fifty amino acids and the largest is about three thousand amino acids long. Protein synthesis occurs on ribosomes in the cytoplasm of a cell but is controlled by DNA located in the nucleus.

One of the fundamental discoveries of the 20th century was that DNA was the genetic code’s physical structure (Watson & Crick, 1953) and, since then, many studies have disclosed the complicated pattern of regulation and expression of genes, which involve RNA synthesis and its subsequent translation into proteins.
