Question

what is a transcription and show the diagram of a transcription

Answer 1

transcription is the formation of mRNA on DNA templates the process take place in presence of DNA dependent RNA polymerase in this process genetic information from DNA is copied into RNA therefore the process is called transcription.

diagram from book you can take

Answer 2

Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairsof nucleotides as a complementary language. During transcription, a DNA sequence is read by an RNA polymerase, which produces a complementary, antiparallel RNA strand called a primary transcript.
