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: an overview of DNA transcription (article) | Khan Academy
Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go ...

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 the processes of transcription and translation in cells, including how genetic information is converted into proteins.
Transcription and translation - Student Academic Success
Transcription and translation are the processes that turn the instructions found in genes into the proteins they encode. Information is transcribed from DNA into RNA and then translated into protein structure.
10.3: Steps of Transcription - Biology LibreTexts
Step 3: Termination Termination is the ending of transcription, and occurs when RNA polymerase crosses a stop (termination) sequence in the gene. The mRNA strand is complete, and it detaches from DNA. This video provides a review of these steps. You can stop watching the video at 5:35.
