Transcription is the process of copying a segment of DNA into RNA for the purpose of gene expression. Some segments of DNA are transcribed into RNA molecules that can encode proteins, called messenger RNA (mRNA). Other segments of DNA are transcribed into RNA molecules called non-coding RNAs (ncRNAs).
Transcription (linguistics), the representations of speech or signing in written form Orthographic transcription, a transcription method that employs the standard spelling system of each target language; Phonetic transcription, the representation of specific speech sounds or sign components; service and software
Transcription in the linguistic sense is the systematic representation of spoken language in written form. The source can either be utterances ( speech or sign language ) or preexisting text in another writing system .
Several cell function specific transcription factor proteins (in 2018 Lambert et al. indicated there were about 1,600 transcription factors in a human cell [41]) generally bind to specific motifs on an enhancer [22] and a small combination of these enhancer-bound transcription factors, when brought close to a promoter by a DNA loop, govern the ...
Transcription and transposition errors are found everywhere, even in professional articles in newspapers or books. They can be missed by editors quite easily, just as they can be created quite easily. The most obvious cure for the errors is for the user to watch the screen when they type, and to proofread.
All these steps involve a series of interactions to initiate and complete the transcription of DNA in the nucleus of eukaryotes. Certain factors play key roles in the activation and inhibition of transcription, where they regulate primary transcript production. Transcription produces primary transcripts that are further modified by several ...
Other transcription factors differentially regulate the expression of various genes by binding to enhancer regions of DNA adjacent to regulated genes. These transcription factors are critical to making sure that genes are expressed in the right cell at the right time and in the right amount, depending on the changing requirements of the organism.
Transcription can also be studied at the level of individual cells by single-cell transcriptomics. Single-cell RNA sequencing (scRNA-seq) is a recently developed technique that allows the analysis of the transcriptome of single cells, including bacteria . [ 25 ]
