1. the transfer of information.
2. the synthesis of RNA using a DNA template catalyzed by an RNA polymerase; the base sequences of the RNA and the DNA template are complementary.

Transfer of genetic code information from one kind of nucleic acid to another, especially with reference to the process by which a base sequence of messenger RNA is synthesized (by an RNA polymerase) on a template of complementary DNA.

1. The act or process of transcribing.
2. Genetics The synthesis of messenger RNA from a DNA template through the formation of base pairs, resulting in a transfer of genetic information that codes for amino acid sequences composing proteins.

transcriptionthe formation of RNA from a DNA template. The RNA may be rRNA or tRNA which are used directly, or mRNA which is translated into protein (see PROTEIN SYNTHESIS). The process can be divided into a number of steps (see Fig. 301 ):
- (a) the DNA double helix unwinds.
- (b) only one DNA POLYNUCLEOTIDE CHAIN serves as a template (the CODING STRAND or sense strand) in any one region, although both chains will act as templates in different locations.
- (c) the enzyme RNA polymerase catalyses the synthesis of an RNA molecule from RIBONUCLEOTIDES with bases complementary to the DNA base sequence, starting at the transcription start site on DNA. Growth of the RNA chain is from 5′ to 3′, the same as in DNA synthesis.
- (d) transcription continues until a transcription terminator signal is reached.
- (e) in eukaryotes the new RNA molecule (transcript) leaves the DNA of the nucleus and moves to the cytoplasm, where it will function as TRANSFER RNA, MESSENGER RNA or RIBOSOMAL RNA. In prokaryotes the new RNA molecule is synthesized in the cytoplasm.
- (f) the two chains of the DNA molecule reanneal to restore the duplex as transcription proceeds.
