The Biology of mRNA: Structure and Function

Her laboratory uses Proteomic, RNomic and biochemical approaches to study the regulation, dynamics and functional niches of RNA maturation pathways and their implications in neurodegenerative diseases. His laboratory uses single molecule and super-resolution microscopy approaches to study different aspects of gene expression in single cells, including RNA transport and localization, lncRNAs function and mRNP organization.

Messenger RNA

In molecular biology , messenger RNA mRNA is a single-stranded molecule of RNA that corresponds to the genetic sequence of a gene , and is read by a ribosome in the process of synthesizing a protein. This process is slightly different in eukaryotes and prokaryotes , including that prokaryotic RNA polymerase associates with DNA-processing enzymes during transcription so that processing can proceed during transcription. In addition, the RNA is unable to form structures from base-pairing. This pre-mRNA usually still contains introns , regions that will not go on to code for the final amino acid sequence. These are removed in the process of RNA splicing , leaving only exons , regions that will encode the protein. This exon sequence constitutes mature mRNA.

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 RNA typically is a single-stranded biopolymer.

Metrics details. A challenge in regulating mRNA processing is how to recognize the actual mRNA processing sites, such as splice and polyadenylation sites, when the sequence content is insufficient for this purpose. The regulatory role of this RNA structure feature is further confirmed by experimental validation. We also identify an RNA structure feature comprising two close-by single-stranded regions that is specifically associated with both polyadenylation and alternative polyadenylation events. We successfully identify pre-mRNA structure features associated with splicing and polyadenylation at whole-genome scale and validate an RNA structure feature which can regulate splicing.

In vivo nuclear RNA structurome reveals RNA-structure regulation of mRNA processing in plants

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.

 - Нет. Хейл сжал ее горло. - Если вы вызовете службу безопасности, она умрет. Стратмор вытащил из-под ремня мобильник и набрал номер. - Ты блефуешь, Грег.

Ее снова сжали уже знакомые ей стальные руки, а ее голова была намертво прижата к груди Хейла. - Боль внизу нестерпима, - прошипел он ей на ухо. Колени у Сьюзан подкосились, и она увидела над головой кружащиеся звезды. ГЛАВА 80 Хейл, крепко сжимая шею Сьюзан, крикнул в темноту: - Коммандер, твоя подружка у меня в руках. Я требую выпустить меня отсюда.

 Подожди минутку! - махнул он рукой, словно прося ее остановиться.

Потом изобразил смущенную улыбку. - Неужели это так заметно. - Как ее зовут? - Женщина лукаво подмигнула. - Меган, - сказал он печально. - Я полагаю, что у вашей подруги есть и фамилия.

СЛЕДОПЫТ ЗАПУЩЕН Сьюзан знала, что пройдет несколько часов, прежде чем Следопыт вернется. Она проклинала Хейла, недоумевая, каким образом ему удалось заполучить ее персональный код и с чего это вдруг его заинтересовал ее Следопыт. Встав, Сьюзан решительно направилась подошла к терминалу Хейла.

Лет пятнадцати-шестнадцати. Волосы… - Не успев договорить, он понял, что совершил ошибку. Кассирша сощурилась. - Вашей возлюбленной пятнадцать лет.

Он очень о многом ей не сказал - о многих вещах, которых теперь стыдился. Она была его иллюзией, его живой фантазией. Он мечтал о ней по ночам, плакал о ней во сне.
