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.
As mentioned earlier, however, there are three fundamental differences that account for the very different functions of the two molecules. RNA is a single-stranded nucleic acid. RNA nucleotides have a uracil base instead of thymine. Their phosphates, sugars, and bases show the same bonding patterns to form nucleotides and their nucleotides bind to form nucleic acids in the same way.
3.4A: DNA and RNA
DNA deoxyribonucleic acid and RNA ribonucleic acid are very similar molecules that serve very different functions. DNA is responsible for long term storage of the genetic code. It resides in the nucleus of eukaryotic cells. RNA, on the other hand, is responsible for several important processes including transporting the genetic information found in DNA to other sites in the cell where it can be used to make proteins. It is found in the cytoplasm of a cell. Each one is made up of nucleotides.
What is the difference between DNA and RNA
Although, both are different in structure, function and nature. It is genetic material of prokaryotes as well as eukaryotes. And transfers information from one generation to another. Consequently, it produces different traits or phenotypes to perform different functions. However, RNA as a genetic material only found in some of the viruses called retrovirus but not as the genetic material of us. Still, it performs unique functions in other prokaryotes and eukaryotes.
DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is found in the nucleus of eukaryotes and in the chloroplasts and mitochondria. In prokaryotes, the DNA is not enclosed in a membranous envelope, but rather free-floating within the cytoplasm. The entire genetic content of a cell is known as its genome and the study of genomes is genomics. In eukaryotic cells, but not in prokaryotes, DNA forms a complex with histone proteins to form chromatin, the substance of eukaryotic chromosomes.

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.
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.

DNA is a deoxyribonucleic acid and is a hereditary material in all living organism. It is located in the nucleus of cell which is known as nuclear DNA. Do you know who had reported first time nucleic acids in - Friedrich Miescher from nuclei of pus cells. How Genetics define the hereditary characteristics of human? It occurs inside the nucleus of cell and some cell organelles but it plants it is present in mitochondria and plant cell. It has two nucleotide strands consisting of phosphate group, five carbon sugar stable deoxyribose 2 and four nitrogen bases. It is single stranded consisting of phosphate group, five carbon sugar less stable ribose and four nitrogen base.
RNA , abbreviation of ribonucleic acid , complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA deoxyribonucleic acid as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides nitrogenous bases appended to a ribose sugar attached by phosphodiester bonds, forming strands of varying lengths. The ribose sugar of RNA is a cyclical structure consisting of five carbons and one oxygen. The structure of the RNA molecule was described by R.
Перечень этой бесценной информации был нескончаем. Всяческие вторжения, способные повредить американской разведке, абсолютно исключались. Конечно, офицеры АНБ прекрасно понимали, что вся информация имеет смысл только в том случае, если она используется тем, кто испытывает в ней необходимость по роду работы. Главное достижение заключалось не в том, что секретная информация стала недоступной для широкой публики, а в том, что к ней имели доступ определенные люди. Каждой единице информации присваивался уровень секретности, и, в зависимости от этого уровня, она использовалась правительственными чиновниками по профилю их деятельности.

Понимаю. - В голосе звонившего по-прежнему чувствовалась нерешительность. - Ну, тогда… надеюсь, хлопот не. - Отлично. Он обедает там сегодня с одной из наших сопровождающих.
Так вот какова месть Танкадо. Уничтожение ТРАНСТЕКСТА. Уже несколько лет Танкадо пытался рассказать миру о ТРАНСТЕКСТЕ, но ему никто не хотел верить.
Он проявил редкую наблюдательность. - Но ведь вы ищете ключ к шифру, а не ювелирное изделие. - Конечно. Но я думаю, что одно с другим может быть связано самым непосредственным образом. Сьюзан отказывалась его понимать.
