examples of nucleic acids

This determination, in the 1990's, has lead to increased research regarding these genes and their mutations in an effort to reduce the risk of acquiring breast cancer. The nucleic acids DNA and RNA differ in composition and structure. Each nucleotide that makes up a nucleic acid is comprised of phosphoric acid, sugar (5-carbon), and nitrogenous base. In addition, they contain a high level of proteins and dietary fiber. A nucleotide contains 3 components: a nitrogenous base, a phosphate group and a 5-carbon sugar. The polymers have backbones made of phosphate and sugar combined by ester bonds. If it is deoxyribose, then its polymer is DNA. DNA is composed of a phosphate-deoxyribose sugar backbone and the four nitrogenous bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Mutations of the genes BRCA1 and BRCA2 have been linked to causing breast cancer.

Rarely, adult onset Tay-Sachs will begin in one's 30's or 40's; but, many times it is not fatal. While certainly not as debilitating as some other genetic diseases, color blindness is also a result of mutation of genes on DNA. The Difference Between Purines and Pyrimidines. Nucleic acids are so vital in the body that if any form of mutation occurs, it can be fatal. DNA is made up of two polymers that are formed by smaller units called nucleotides. Information is encoded by the sequence of the 4 neuclobases. Thymine Definition, Facts, and Functions.

Nucleic Acids - Structure and Function. The most common nucleic acids in nature are DNA and RNA. Nucleic acids are composed of nucleotide monomers linked together. Understanding the Double-Helix Structure of DNA. Similar to what happens with protein and carbohydrate monomers, nucleotides are linked together through dehydration synthesis. Examples of such fishes are salmon, tuna and sardines. Nucleic acids include DNA and RNA. When DNA is transcribed into an RNA transcript during DNA transcription, guanine pairs with cytosine (G-C) and adenine pairs with uracil (A-U). If it is deoxyribose, then its polymer is DNA. DNA commonly exists as a double-stranded molecule with a twisted double-helix shape. In DNA, the five-carbon sugar is deoxyribose, while ribose is the pentose sugar in RNA. All Rights Reserved, Model of chemical bonds as examples of nucleic acids.

How Are They Connected?

If the sugar is ribose, then its polymer is RNA.
If a mutated gene is inherited, the likelihood of acquiring Alzheimer's by the age of 65 is very high. The many examples of nucleic acids including RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) are composed of monomers called nucleotides. A genetic code is used to read the information and elaborates the arrangement of amino acids in proteins. Current time: 11/03/2020 02:21:43 am (America/New_York)

Nucleic acids are macromolecules that store genetic information and enable protein production. This means that the 5′-phospho… It helps in building up your DNA.

Alzheimer's Disease is another disease caused by mutation of genes in one's DNA. Nucleic acids and proteins are definitely the most essential biological macromolecules. Fruit is a great source of nucleic acids. The differences are listed as follows: DNA is commonly found in its three-dimensional, double-helix shape. Presenilin-1, Presenilin-2, and APP are three genes that are known to contribute to the onset of Alzheimer's.
DNA holds the genetic information which is important in the functioning and development of all living things. The Differences Between DNA and RNA. Nucleotide strings are strung together in a particular sequence, which is a mechanism that enables storage and transmission of both genetic and hereditary information through protein synthesis. Why Are Your Nails Splitting Down Middle. Memory usage: 1436.56KB, 8 Easy Remedies to Remove Dandruff Quickly, Coconut Milk for Hair: 8 Ways to Get the Benefits. For this reason, the name was modified to its present name - nucleic acid. Copyright © 2020 LoveToKnow. The base pairing causes RNA to fold, forming various shapes. These macromolecules store the genetic information that determines traits and makes protein synthesis possible. When there is damage to the mitochondrial DNA, tissues and organs can begin to deteriorate causing painful and sometimes fatal conditions. Last Updated 03 November, 2020. When there is damage to the mitochondrial DNA, tissues and organs can begin to deteriorate causing painful and sometimes fatal conditions. While RNA does not take on a double-helix shape like DNA, this molecule is able to form complex three-dimensional shapes. Interestingly, some nucleotides perform important cellular functions as "individual" molecules, the most common example being adenosine triphosphate or ATP, which provides energy for many cell functions. These components are found in DNA and RNA of every living thing on the planet. Down Syndrome is another condition that is caused by a mutation of a gene in the DNA. In the past several decades, great strides have been made in medicine in understanding and diagnosing Down Syndrome. The main function of RNA is to convert the genetic information encoded in the genes into amino acid sequences of proteins. DNA Definition and Structure. Johann Friedrich Miescher (1844-1895), a Swiss biochemist, discovered nucleic acids in 1869. There are several conditions that can result from mutations of nucleic acids. Cystic Fibrosis is an inherited disease that affects the secretory glands that are responsible for producing mucus and sweat.
