Transcription (biology) - Wikipedia
Transcription is the process of duplicating 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). Both DNA and RNA are nucleic acids, composed of nucleotide sequences. During ...
Transcription in Biology – Steps, Functions, Regulation
Transcription is the first step of gene expression, making an RNA copy of a specific segment of DNA by the enzyme RNA polymerase. The RNA transcript carries the genetic instructions from DNA to the ribosome, where proteins are synthesized during translation. Transcription is a fundamental process in all living cells and occurs in both prokaryotes and eukaryotes, although the mechanisms and ...
Transcription | Definition, Steps, & Biology | Britannica
Transcription of any one gene takes place at the chromosomal location of that gene, which is a relatively short segment of the chromosome. The active transcription of a gene depends on the need for the activity of that particular gene in a specific cell or tissue or at a given time.

Transcription - National Human Genome Research Institute
Transcription, as related to genomics, is the process of making an RNA copy of a gene’s DNA sequence. This copy, called messenger RNA (mRNA), carries the gene’s protein information encoded in DNA. In humans and other complex organisms, mRNA moves from the cell nucleus to the cell cytoplasm (watery interior), where it is used for synthesizing the encoded protein.

Learn about transcription, through which the DNA sequence of a gene is transcribed (copied out) to make an RNA molecule.
Stages of transcription: initiation, elongation & termination (article ...
Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.
