How does transcription differ from DNA replication? How is it the same? What is the role of complementary base-pairing in each? If a section of the DNA strand to be transcribed is CTAATGT, what is the corresponding section of the mRNA? *PLEASE SIMPLIFY*© BrainMass Inc. brainmass.com October 9, 2019, 4:24 pm ad1c9bdddf
Transcription is RNA synthesis and takes place on a DNA strand template to make some type of RNA: either rRNA, mRNA or tRNA. All of these RNAs are used for protein synthesis. Therefore, transcription is needed for translation. Translation is another word for protein synthesis.
DNA replication is DNA synthesis and takes place in order to double the amount of DNA in the nucleus so that when the nucleus divides in mitosis each new nucleus will have the right amount (usually the diploid number)of DNA.
