You can DOWNLOAD Microsoft has announced that as part of its commitment to accessibility, Skype is offering real-time call transcriptions from today. The transcribed DNA message, or RNA transcript, is used to produce  proteins. Transcription is the transfer of genetic information from a) DNA to RNA b) tRNA to mRNA c) DNA to mRNA d) mRNA to tRNA 4. These proteins bind to specific short sequences in DNA. Again, a section of DNA double helix is uncoiled and only one of the DNA strands serves as a template for RNA polymerase enzyme to guide the synthesis of RNA. Targeting. Transcription is defined as the synthesis of RNA from a DNA template. The key difference between transcription and translation in DNA is that transcription is the production of an mRNA sequence which contains the genetic code encoded in the coding sequence of the gene while translation is the production of a functional protein using the genetic code encoded in the mRNA sequence.
