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.

The 3 Types of RNA and Their Functions

RNA, in one form or another, touches nearly everything in a cell. RNA carries out a broad range of functions, from translating genetic information into the molecular machines and structures of the cell to regulating the activity of genes during development, cellular differentiation, and changing environments. RNA is a unique polymer. It can also bind specific proteins or small molecules, and, remarkably, RNA can catalyze chemical reactions, including joining amino acids to make proteins. Genes that are copied—"transcribed"—into the instructions for making individual proteins are often referred to as "coding genes. Several key classes of RNA molecules help convert the information contained in the cell's DNA into functional gene products like proteins. Messenger RNAs mRNAs are copies of individual protein-coding genes, and serve as an amplified read-out of each gene's nucleic acid sequence.

Ribonucleic acid RNA occurs in different forms within organisms and serves many different roles. Listed here are the types of RNA, grouped by role. Abbreviations for the different types of RNA are listed and explained. From Wikipedia, the free encyclopedia. See also: Category:RNA.

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. Holley in

 Что-что. - Как это тебе нравится. Он аккуратно размазал приправу кончиком салфетки. - Что за отчет. - Производственный.

Сьюзан была убеждена, что это невозможно. Угрожающий потенциал всей этой ситуации подавил. Какие вообще у них есть доказательства, что Танкадо действительно создал Цифровую крепость. Только его собственные утверждения в электронных посланиях.

Пока техники тщетно старались отключить электропитание, собравшиеся на подиуме пытались понять расшифрованный текст.

Role of RNA in Biology

 - Если Танкадо ничего не заподозрил, нам придется ответить на ряд вопросов. - Как у нас со временем, Джабба? - спросил Фонтейн. Джабба посмотрел на ВР. - Около двадцати минут.

Она села и начала, подобно пианисту-виртуозу, перебирать клавиши Большого Брата. Бринкерхофф посмотрел на мониторы, занимавшие едва ли не всю стену перед ее столом. На каждом из них красовалась печать АНБ. - Хочешь посмотреть, чем занимаются люди в шифровалке? - спросил он, заметно нервничая. - Вовсе нет, - ответила Мидж.  - Хотела бы, но шифровалка недоступна взору Большого Брата.
