The translation is performed by a large complex of functional RNA and proteins called ribosomes. The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide.
Eukaryotic translation is the biological process by which messenger RNA is translated into proteins in eukaryotes. It consists of four phases: initiation, elongation, termination, and recapping. It consists of four phases: initiation, elongation, termination, and recapping.
Retroviruses were shown to have a single-stranded RNA genome and to replicate via a DNA intermediate, the reverse of the usual DNA-to-RNA transcription pathway. They encode a RNA-dependent DNA polymerase (reverse transcriptase) that is essential for this process. Some retroviruses can cause diseases, including several that are associated with ...
Transcription is the process by which the information contained in a section of DNA is replicated in the form of a newly assembled piece of messenger RNA (mRNA). Enzymes facilitating the process include RNA polymerase and transcription factors. In eukaryotic cells the primary transcript is pre-mRNA. Pre-mRNA must be processed for translation to ...
Synthesis of RNA typically occurs in the cell nucleus and is usually catalyzed by an enzyme—RNA polymerase—using DNA as a template, a process known as transcription. Initiation of transcription begins with the binding of the enzyme to a promoter sequence in the DNA (usually found "upstream" of a gene).
Small nuclear RNAs found in some species of nematode worms, thought to be involved in mRNA trans-splicing snoRNA: small nucleolar RNA multiple families: snRNA: small nuclear RNA multiple families: snRNP: small nuclear ribonucleic proteins - SPA lncRNA 5' small nucleolar RNA capped and 3' polyadenylated long noncoding RNA - SRP RNA: signal ...
In 2019, a team sequenced RNA from the skin of a 14,300-year-old wolf that was preserved in permafrost, but the latest research is the first time RNA has been retrieved from an animal that is now ...
The pre-mRNA lacks structures that the messenger RNA (mRNA) requires. First all introns have to be removed from the transcribed RNA through a process known as splicing. Before the RNA is ready for export, a Poly(A)tail is added to the 3' end of the RNA and a 5' cap is added to the 5' end.
