It is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA).
Translation is the process by which a protein is synthesized from the information contained in a molecule of messenger RNA (mRNA). Transcription. Definition. 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 is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes. Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase. The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation. Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template. 3. : the process of constructing a messenger RNA molecule using a DNA molecule as a template with resulting transfer of genetic information to the messenger RNA — compare translation 2, reverse transcription. — tran·scrip·tion·al \-shnəl, -shə-nəl\ adjective. — tran·scrip·tion·al·ly adverb. Medical Definition of TRANSCRIPTION. : the process of constructing a messenger RNA molecule using a DNA molecule as a template with resulting transfer of genetic information to the messenger RNA—compare reverse transcription, translation.
