The structure of RNA is a single-stranded molecule made up of basic units called nucleotides that contain a nitrogenous base, a five-carbon sugar and a phosphate group. Although there is only one strand of RNA, as opposed to the two stranded double helix of DNA, it does...
Ribonucleic acid, known as RNA, is composed of a combination of four different nucleotides: adenine, uracil, guanine and cytosine. Each nucleotide primarily consists of a ribose sugar (five-carbon ring) and a phosphate group.
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.
There are three main types of RNA. They are messenger RNA (mRNA), ribosomal RNA (rRNA) and transfer RNA (tRNA). These three types of molecules perform different functions in gene coding and regulation.
DNA and RNA are nucleic acids, which are also considered polymers. Deoxyribonucleic acid is used to create ribonucleic acid that, in turn, contains the primary sequence of amino acids needed to make proteins.
RNA is important to cells because it relays information encoded in DNA to tiny organs within the cell, called ribosomes, which produce protein according to the RNA's instructions. RNA is thus vital to the basic functioning of the cell.
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.
