Transcription is the process by which genetic information from DNA is transferred into RNA. DNA sequence is enzymatically copied by RNA polymerase to produce a complementary nucleotide RNA strand.
Transcription factor
Transcription factors are proteins that directly regulate the gene transcription machinery.

transcription
the synthesis or RNA from a DNA template; in retroviruses, it is the synthesis of DNA from an RNA template; can also include the synthesis of DNA from a DNA template (replication) ...
Transcription = DNA → RNA
Translation = RNA → protein
Taken together, they make up the "central dogma" of biology: DNA → RNA → protein.
Here is an overview.
Transcription is the synthesis of mRNA from a DNA template.
It is like DNA replication in that a DNA strand is used to synthesize a strand of mRNA.
Only one strand of DNA is copied.
transcription
noun
It is the process of transcribing or making a copy of genetic information stored in a DNA strand into a complementary strand of RNA (messenger RNA or mRNA) with the aid of RNA polymerases.
Transcription
Transcription is the process of making an RNA copy of a gene sequence.

reverse transcription Process of transcribing a single-stranded DNA from a single-stranded RNA (the reverse of transcription); used by retroviruses as well as in biotechnology.
Transcription only requires one strand of the DNA double helix. This is called the coding strand. The transcription starts with initiation.
Transcription start site
Site within a gene where transcription of RNA begins.
Terminator
The site on a DNA sequence at which transcription and DNA replication stops. Cf. origin.
Transcription of mRNA from the lac operon will be high.

Transcription factor
sometimes, interactions between different proteins. Proteins called transcription factors bind to DNA sequences, known collectively as regulatory elements, located near the coding region of the gene in question
(Fig. 1).
An unregulated promoter that allows for continual transcription of its associated gene. (See Promoter.) Contiguous (contig) map.
5' - end -- the end of a polynucleotide with a free (or phosphorylated or capped) 5' - hydroxyl group; transcription/translation begins at this end.
Transcription terminator A short base sequence found at the 3' end of a gene which causes the RNA polymerase to stop transcription.
TransfectionA general term to describe the introduction of recombinant or vector DNA into host cells.
Usually associated with transcription-initiation regions of (housekeeping) genes transcribed at low rates that do not contain a TATA box.
The replication process of HIV is associated with a very high mutation rate because reverse transcription does not allow for correction of errors in nucleotide incorporation.
Chromosomes are unwound when they are "working" (taking part in transcription or replication).
dsRNA silencing A method used to induce post-transcriptional silencing of a target gene with the intention of generating a 'knock out' mutant phenotype.
It is not clear whether this claim is a simple fabrication or whether it is an erroneous transcription from another source.
Examples include binding sites for transcription factors and splicing machinery.

Activation domain The structural region of a transcription factor that facilitates transcription in some manner. See also DNA-binding domain.
Active site A specific region of an enzyme that binds the substrate and carries out catalysis.
A regulatory region a short distance upstream from the 5' end of a transcription start site that acts as the binding site for RNA polymerase. A region of DNA to which RNA polymerase binds in order to initiate transcription.
Control elements: DNA sequences in genes that interact with regulatory proteins (such as transcription factors) to determine the rate and timing of expression of the genes as well as the beginning and end of the transcript.
The fourth stage of prophase 1 of meiosis, following the pachytene stage, in which there is continued shortening and thickening of the chromosomes. Final gene transcription is completed, after which diakinesis occurs.
This also has the advantage that little effort is required to pull the two halves apart for replication, when the DNA is copied, and for transcription, when the DNA message is read.
