Transcription is carried out by a DNA-dependent RNA polymerase that copies the sequence of a DNA strand into RNA. To begin transcribing a gene, the RNA polymerase binds to a sequence of DNA called a promoter and separates the DNA strands.
DNA replication is the process by wich one double helix of DNA is dublicated into two identical double helices which are also identical to the mother DNA. The process is carriâ¦ed by specific enzymes. RNA transcription is the process by which a messanger RNA copy of the active strand of a DNA helix is made. This process is carried by different enzymes and the result is a single strand of mRNA.
