In virology, the term transcription is used when referring to mRNA synthesis from a viral RNA molecule. The genome of many RNA viruses [a] is composed of negative-sense RNA which acts as a template for positive sense viral messenger RNA - a necessary step in the synthesis of viral proteins needed for viral replication.
Schematics of RT-LAMP amplification, exemplified for SARS-CoV-2 detection. Reverse transcription loop-mediated isothermal amplification (RT-LAMP) is a one step nucleic acid amplification method to multiply specific sequences of RNA. It is used to diagnose infectious disease caused by RNA viruses.
Transcription was originally a process carried out manually, i.e. with pencil and paper, using an analogue sound recording stored on, e.g., a Compact Cassette. Nowadays, most transcription is done on computers. Recordings are usually digital audio files or video files, and transcriptions are electronic documents.
General transcription jobs, specifically remote transcription positions, typically involve transcribing audio and video files into a written document or electronic document in a variety of fields.
t. e. Eukaryotic Transcription. Eukaryotic transcription is the elaborate process that eukaryotic cells use to copy genetic information stored in DNA into units of transportable complementary RNA replica. [1] Gene transcription occurs in both eukaryotic and prokaryotic cells. Unlike prokaryotic RNA polymerase that initiates the transcription of ...
Template-switching polymerase chain reaction (TS-PCR) is a method of reverse transcription and polymerase chain reaction (PCR) amplification that relies on a natural PCR primer sequence at the polyadenylation site, also known as the poly (A) tail, and adds a second primer through the activity of murine leukemia virus reverse transcriptase. [1]
t. e. Transcription is the process of copying DNA into RNA, usually mRNA. Bacterial transcription is the process in which a segment of bacterial DNA is copied into a newly synthesized strand of messenger RNA (mRNA) with use of the enzyme RNA polymerase. The process occurs in three main steps: initiation, elongation, and termination; and the end ...
The polypeptide chain then folds and is post-translationally modified. Protein biosynthesis (or protein synthesis) is a core biological process, occurring inside cells, balancing the loss of cellular proteins (via degradation or export) through the production of new proteins. Proteins perform a number of critical functions as enzymes ...
