RNA and DNA are both molecules containing the genetic information that is necessary for life. Both molecules are composed of nucleotides, which are chemical structures consisting of a sugar, a phosphate and a nitrogenous base. Nucleotides are linked by alternating sugar and phosphate bonds.Know More
Though the general structure of the nucleotides in both RNA and DNA is the same, there is a key difference. Each molecule contains a different type of sugar. The sugar in RNA is ribose, while the sugar in DNA is deoxyribose. The full names of DNA and RNA, deoxyribonucleic acid and ribonucleic acid, are derived from the different type of sugar in each molecule.
The alternating sugar and phosphate bonds create long strands in both DNA and RNA. The molecules differ in the number of strands making up each. DNA is double-stranded, shaped like a ladder with rungs between both sides. RNA is single-stranded.
The function of DNA is the storage of genetic information. DNA is located in the nucleus and must remain there. RNA travels from the nucleus through the cell's cytoplasm to the ribosome. It carries the information from the DNA to the ribosome so that it can be decoded to make proteins.
Genetic information is coded by using the chemicals adenine, guanine, thymine and cytosine in DNA. RNA uses the same chemicals as DNA to store genetic information, with the exception of thymine. RNA replaces thymine with a chemical called uracil.Learn more about Molecular Biology & DNA
RNA, or ribonucleic acid, is a family of biological molecules that function in gene synthesis, regulation and expression. Along with DNA, RNA plays an active role in transcribing and translating genes and proteins that make up the human body.Full Answer >
Ribonucleic acid, also known as RNA, is found almost exclusively in the cytoplasm of cells, although at times it can created in the nucleus of the cell. RNA is a major biological macromolecule that is required for life.Full Answer >
The process of assembling a protein from RNA is called translation. A strand of messenger RNA, or mRNA, travels from the nucleus of a cell to the ribosomes, the site where proteins are assembled.Full Answer >
The four bases found in RNA are guanine, cytosine, adenine and uracil. Typically, these four bases are abbreviated and listed as G, C, A and U. RNA, which stands for ribonucleic acid, is a molecule that is made up of one or more nucleotides.Full Answer >
