Comparison chart | DNA | RNA | Definition: | A nucleic acid that contains the genetic instructions used in the development and functioning of all known living organisms | RNA, single-stranded chain of alternating phosphate and ribose units with the bases adenine, guanine, cytosine, and uracil bonded to the ribose. RNA molecules are involved in protein synthesis and sometimes in the transmission of genetic information. | Job/Role: | Medium of long-term storage and transmission of genetic information | The main job of RNA is to transfer the genetic code need for the creation of proteins from the nucleus to the ribosome. this process prevents the DNA from having to leave the nucleus, so it stays safe.

Transcription is the beginning of the process that ultimately leads to the translation of the genetic code into a peptide or protein.
Three types of RNA are transcribed from DNA: * Messenger RNA (mRNA) * Ribosomal RNA (rRNA) * Transfer RNA (tRNA)
Messenger RNA is a copy of the genetic information that was transcribed from the DNA.
This copy is brought to the ribosome and “decoded” by tRNA and rRNA. Ribosomal RNA (rRNA) is part of the structure of ribosomes, the cellular protein factories where peptides are built. Transfer RNA (tRNA) brings to the ribosome the amino acids that mRNA coded for.
Translation
Ribosomes (which contain rRNA) make proteins from the messages encoded in mRNA.
Each three nucleotide group, called a codon, encodes one amino acid. This is the genetic code. In other words, the triplet code of genetic instructions for a polypeptide chain is ‘written’ in the DNA as a series of 3-nucleotide ‘words.’
These genetic instructions are brought to the ribosome by mRNA, decoded by rRNA, and tRNA brings the amino acid monomers that were coded for in the base triplet of mRNA. Amino acids are monomers that, when linked together with peptide bonds, ultimately become a protein molecule, the end product of
The small ribosomal subunit, amongst other things, is initiates the engagement of the mRNA and is responsible decoding the genetic information during translation [4].
This a brief written report on the role of DNA, RNA and transmission on information within a cell to create amino acids.
3) As a ribosome moves along the mRNA, the genetic message is translated into a protein with a specific amino acid sequence.
Ribonucleic acid (RNA): It is a single nucleic acid supported by adenine, guanine, cytosine and uracil supported by ribose sugars. mRNA, rRNA and tRNA.
After the DNA has been turned into mRNA a process called translation occurs and it turns the mRNA into tRNA.
Translation is a task that makes ribosomes synthesize proteins utilizing mRNA transcript made during transcription. In the begining of this task mRNA attaches it self to a ribosome so that it can be reveal a codon (three nucleotides).
A gene is a region of a nucleic acid that contains hereditary biological information. For all cells, the nucleic acid is double stranded DNA, and it provides information for synthesis of RNA, and into protein, which is then expressed as hereditary traits in human.
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
It provides a base triplet, a sequence of three bases on one of the strands of DNA, that code for one amino acid. The sequence of base triplets on DNA molecules determines the order of the amino acids on the protein chain. In the first phase of transcription, the first process of protein synthesis that occurs in the nucleolus, a portion of a DNA molecule unwinds and serves as a template. Free nucleotides floating in the nucleoplasm pair up with their complimentary bases on the DNA strand.
There is some redundancy in the code as most of the amino acids may be encoded by more than one codon. Moreover, the code can be expressed as RNA or DNA codons with the former being used during translation (i.e. creation of proteins) after acquiring its sequence of nucleotides from the latter during transcription (i.e. copying of DNA into mRNA).
During the process of transcription, the information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus. Both RNA and DNA are made up of a chain of nucleotide bases, but they have slightly different chemical properties. The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.
1) How does RNA differ from DNA? According to the video, RNA is made of nucleotide building block, but is a single stranded. DNA often exists as a double stranded molecule made of four building blocks called nucleotides. RNA contains Uracil as DNA contains Thymine.
Proteins are the building blocks of the cells. Without them our cells would not have the genetic code they need to build up our bodies. Proteins are synthesised or made in the ribosome with the help of DNA and RNA. DNA is a double helix, or a twisted ladder shape, found in the nucleus and contains the genetic code for organisms. RNA is found in the nucleus or in ribosomes and is composed of the nucleotides ribose, phosphate group, and nitrogenous base. While in the nucleus, the RNA copies the genetic code from the DNA and then it leaves the nucleus to go to a ribosome to pass the genetic code to the protein. These two processes are called transcription and translation.
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.
DNA, or deoxyribonucleic acid, is considered a genetic material that organisms inherit from their parents after reproduction (Simon, E.J. (2017). Biology: The Core (2nd Edition). Retrieved from https://etext.pearson.com). This acid, DNA, is what instructs RNA, or ribonucleic acid, to produce proteins. Moreover, both DNA and RNA are nucleic acids, which are information storage molecules that contain instructions, both of these nucleic acids contain some common features as well as differences. After RNA is directed to make proteins, the manufacturing of proteins is controlled and then proteins preform the majority of a cell’s functions (Simon, E.J. (2017). Biology: The Core (2nd Edition).
