DNA has four nitrogen bases adenine, thymine, cytosine, and guanine and for RNA instead of thymine, it has uracil. Another thing is that DNA is missing an oxygen.
DNA and RNA
However, whereas DNA molecules are typically long and double stranded, RNA molecules are much shorter and are typically single stranded. RNA molecules perform a variety of roles in the cell but are mainly involved in the process of protein synthesis translation and its regulation. RNA is typically single stranded and is made of ribonucleotides that are linked by phosphodiester bonds. A ribonucleotide in the RNA chain contains ribose the pentose sugar , one of the four nitrogenous bases A, U, G, and C , and a phosphate group. The subtle structural difference between the sugars gives DNA added stability, making DNA more suitable for storage of genetic information, whereas the relative instability of RNA makes it more suitable for its more short-term functions. The RNA-specific pyrimidine uracil forms a complementary base pair with adenine and is used instead of the thymine used in DNA.

This is a comparison of the differences between DNA versus RNA, including a quick summary and a detailed table of the differences. This table summarizes the key points:. Also, RNA is found in prokaryotes , which are believed to precede eukaryotes. RNA on its own can act as a catalyst for certain chemical reactions. The most likely answer for this is that having a double-stranded molecule helps protect the genetic code from damage. If one strand is broken, the other strand can serve as a template for repair.
DNA stands for Deoxyribonucleic Acid. The sugar portion of DNA is 2-Deoxyribose. The sugar portion of RNA is Ribose….. Save my name and email in this browser for the next time I comment. RNA stands for Ribonucleic Acid.
Nucleic acid , naturally occurring chemical compound that is capable of being broken down to yield phosphoric acid , sugars, and a mixture of organic bases purines and pyrimidines. Nucleic acids are the main information-carrying molecules of the cell , and, by directing the process of protein synthesis , they determine the inherited characteristics of every living thing. DNA is the master blueprint for life and constitutes the genetic material in all free-living organisms and most viruses. RNA is the genetic material of certain viruses, but it is also found in all living cells, where it plays an important role in certain processes such as the making of proteins.
Viruses are obligatory intracellular pathogens and completely depend on their hosts for survival and reproduction. The strategies adopted by viruses to exploit host cell processes and to evade host immune systems during infections may differ largely with the type of the viral genetic material.

DNA deoxyribonucleic acid is the genomic material in cells that contains the genetic information used in the development and functioning of all known living organisms. DNA, along with RNA and proteins, is one of the three major macromolecules that are essential for life. Within the nucleus of eukaryotic cells, DNA is organized into structures called chromosomes. The complete set of chromosomes in a cell makes up its genome; the human genome has approximately 3 billion base pairs of DNA arranged into 46 chromosomes. DNA consists of two long polymers of simple units called nucleotides, with backbones made of sugars and phosphate groups joined by ester bonds. These two strands run in opposite directions to each other and are therefore anti-parallel. Attached to each sugar is one of four types of molecules called nucleobases bases.
Он не мог понять, как до него не дошло. Росио - одно из самых популярных женских имен в Испании. В нем заключено все, что ассоциируется с представлением о молодой католичке: чистота, невинность, природная красота. Чистота заключена в буквальном значении имени - Капля Росы. В ушах зазвучал голос старого канадца.
What are the key differences between DNA and RNA?
В чем дело? - Беккер не рассчитывал, что все это займет так много времени, и теперь опаздывал на свой обычный субботний теннисный матч. Часовой пожал плечами. - С вами хочет поговорить начальник шифровалки. Она сейчас будет. - Она? - Беккер рассмеялся. Он не заметил в АНБ ни одного существа женского пола. - Вас это смущает? - раздался у него за спиной звонкий голос.
Уверен, ты догадаешься сама, - сказал Стратмор. - Он не очень любит Агентство национальной безопасности. - Какая редкость! - саркастически парировала Сьюзан. - Он участвовал в разработке ТРАНСТЕКСТА.
А вы пробовали сделать ему искусственное дыхание? - предположил Беккер. - Нет. Мы к нему не прикасались.
Мидж отвернулась. Фонтейн стоял очень прямо, глядя прямо перед. У Бринкерхоффа был такой вид, словно он вот-вот лишится чувств.
