RNA is the acronym for ribonucleic acid. It is a nucleic acid that is responsible for transferring genetic information from DNA in order to synthesize proteins according to the functions and characteristics indicated. RNA is present in the cytoplasm of eukaryotic and prokaryotic cells. Also, the RNA is composed of a simple chain that can sometimes be duplicated. It is made up of bonded nucleotides that form chains. Each nucleotide consists of: a sugar (ribose), a phosphate group and 4 nitrogen bases (adenine, guanine, uracil and cytosine).
RNA carries the genetic information of DNA for the synthesis of the necessary proteins. That is, the RNA copies the information of each DNA gene and then goes to the cytoplasm, where it binds to the ribosome to direct protein synthesis.
RNA begins to be studied in 1868 by Friedrich Miescher, also, he was the first person to investigate DNA and promote the study of nucleic acids. The international abbreviation is RNA for its acronym in English for ribonucleic acid. Click to see more definition.
In reference to the above, we can distinguish the interaction of various types of RNA in genetic expression, among which we have:
- Messenger RNA(mRNA): known as coding RNA, it has the genetic code that determines the scheme of amino acids to form a protein;
- RNA transfer(tRNA): is responsible for carrying amino acids to ribosomes in order to incorporate them into the process of protein synthesis, likewise, it is responsible for encoding the information that messenger RNA possesses to a protein sequence and, finally,
- Ribosomal RNA(rRNA): it is part of the ribosomes and acts in the enzymatic activity, it is responsible for creating the peptide bonds between the amino acids of the polypeptide in the protein synthesis process.
It is also worth mentioning ribozyme, which is a type of RNA with a catalytic function capable of carrying out its self-duplication when there is an absence of proteins. This characteristic is of great importance, since it has to do with the hypothesis that RNA was one of the first forms of life, prior to DNA, and that it allowed the first cell to form, since it contains stored genetic information and can self-duplicate.
RNA and DNA
Between ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) there are differences in their structure and function. RNA groups its proteins in a single helix while DNA groups them in a double helix. The nucleotides that make up the RNA are made up of ribose, a phosphate group and four nitrogenous bases: adenine, guanine, cytosine and uracil.
The nucleotides that form the DNA, on the other hand, are made up of deoxyribose, a phosphate group and four nitrogen bases: adenine, guanine, cytosine and thymine, and it is always found in the nucleus. In reference to its functions, the DNA selects, stores and saves the genetic code, in turn, the RNA transmits the genetic code stored by DNA, that is, it serves as a messenger.
- Key West, Florida - At the southeastern end of the Florida Keys is Key West Island, the southernmost point of the continental United States. If you visit this unique place, you will surely be absolutely enchanted by its beauty, just as the writer Ernest Hemingway was in the past. Right at Key West Airport, you may be a little […]
- Breckenridge, Colorado - In the US state of Colorado, the Breckenridge resort is located in the Rocky Mountains, which together with six other areas form the Summit Country ski area. Copper Mountain, Keystone, Frisco, Dillon, Silverthorne and Leadville are nearby. Sufficient snow cover ensures quality skiing from the beginning of November to the end of April. Nevertheless, snow […]
- What does Diary Stand for? - From the Latin diarĭum, the word diary refers to that which corresponds to every day. For example: “Daily physical activity is recommended for health”, “It is not good to eat hamburgers every day”. On the other hand, a daily is a newspaper that is published every day. It is a printed publication that presents news […]
- What does Detractor Stand for? - In the Latin word “detractor” is where the etymological origin of the term detractor is found, which is composed of the following parts: The prefix “from-“, which is used to indicate “direction from top to bottom” or “away”. The word “tractus”, which can be translated as “dragged”. The suffix “-tor”, which is equivalent to “agent”. […]
- What does PLAN Stand for? - The dictionary of the Royal Spanish Academy (RAE) defines design as an idea, an intention or a purpose that is carried out based on one ‘s own or another ‘s will. A design, therefore, can be a command. Let’s see some example sentences in which these aspects of this word can be appreciated: “By design […]
- What does Fainting Stand for? - The verb to faint is used with reference to causing or suffering a fainting spell (a fainting). The action can be linked to a decrease in strength or loss of consciousness. For example: “When performing intense physical activity, certain precautions must be taken so as not to faint”, “I want to make something clear: our […]
- What does Melt Stand for? - The verb to melt could come from the Latin reterĕre, which alludes to the friction that wears something down. The notion refers to the dissolution of a solid element through the application of heat, which turns it into a liquid. For example: “If you don’t hurry, your ice cream will melt”, ” Global warming could […]
- What does Civil Law Stand for? - The law is inspired by principles of justice and allows the development of laws that regulate the functioning of a society. Civil, on the other hand, refers to what is related to citizens or cities. It is known as civil law that which is responsible for governing the private links that people establish between them. […]
- What does Demand Stand for? - The notion of demand refers to a request, request, plea or request. The one who demands requests that something be given to him. For example: “The kidnapper demands a million pesos to free the hostages”, “The demand for dairy products has grown in recent years”, “The government demands a greater effort from companies to prevent […]
- What does Traditional Tale Stand for? - A story is a fictional story whose length is reduced. Traditional, on the other hand, is that which is linked to tradition (custom or habit). The notion of traditional story refers to the narration whose authorship is generally unknown, which is transmitted from generation to generation orally.
