Ribonucleic acid (RNA) is a polymeric molecule that is essential for most biological functions, either by performing the function itself (non-coding RNA) or by forming a template for the production of proteins (messenger RNA). RNA and deoxyribonucleic acid (DNA) are nucleic acids.

3 天之前 · Ribonucleic acid (abbreviated RNA) is a nucleic acid present in all living cells that has structural similarities to DNA. Unlike DNA, however, RNA is most often single-stranded. An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA.

2023年7月29日 · Ribonucleic acid (RNA) is a molecule that is present in the majority of living organisms and viruses. It is made up of nucleotides, which are ribose sugars attached to nitrogenous bases and phosphate groups. The nitrogenous bases include adenine, guanine, uracil, and cytosine.

2024年4月21日 · Ribonucleic acid (RNA) is typically single stranded and contains ribose as its pentose sugar and the pyrimidine uracil instead of thymine. An RNA strand can undergo significant intramolecular base pairing to take on a three-dimensional structure. There are three main types of RNA, all involved in protein synthesis.

2025年3月27日 · RNA, complex compound of high molecular weight that functions in cellular protein synthesis and replaces DNA as a carrier of genetic codes in some viruses. RNA consists of ribose nucleotides and the nitrogenous bases adenine, guanine, cytosine, and uracil. Learn about the structure, types, and functions of RNA.

Nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), carry genetic information which is read in cells to make the RNA and proteins by which living things function. The well-known structure of the DNA double helix allows this information to be copied and passed on to the next generation.

1 天前 · Each nucleotide in RNA consists of a sugar (ribose), a phosphate group, and a nitrogenous base. There are four nitrogenous bases in RNA: adenine (A), uracil (U), cytosine (C), and guanine (G). These bases are similar to those in DNA, except that thymine (T) in DNA is replaced by uracil (U) in RNA. This difference may seem small, but it has ...

3 天之前 · Adenosine deaminase acting on RNA (ADAR)-mediated RNA base editing offers a safer alternative to genome editing for specific clinical applications because of nonpermanent editing of targets.

RNA consists of four nitrogenous bases: adenine, cytosine, uracil, and guanine. Uracil is a pyrimidine that is structurally similar to the thymine, another pyrimidine that is found in DNA. Like...

2025年3月25日 · Co-transcriptional base pairing has the potential to regulate all eukaryotic RNA processing steps that begin and are often completed during transcription, including pre-mRNA splicing, RNA editing and modification, and 3′-end cleavage. 8, 9 Recent work has established that base pairing is dynamic in living cells, and RNAs can populate multiple structural states while sharing identical ...
